FEATURES AND BENEFITS

Acclaimed as the most durable of

all resilient-seated butterfly valves

in the industry, this valve excels in

a wide variety of applications.

Cast in both wafer and tapped-lug

patterns in a wide variety of material

choices, DEMCO butterfly valves

feature a one-piece body for minimum

weight and maximum strength. The

unique stem hole design in the disc

ensures a dry stem journal and the

hard-backed seat allows ease of

installation, reliable operation, and is

field-replaceable without special tools.

DEMCO butterfly valves are available

in sizes 2 in. through 36 in.

(50 mm through 900 mm).

Engineered for long-term,

maintenance-free performance,

DEMCO butterfly valves are commonly

selected for a variety of applications

spanning a wide range of industries:

• Chemical and petrochemical

• Agriculture

• Oil and gas drilling and production

• Food and beverage

• Water and waste water

• Cooling towers (HVAC)

• Power

• Mining and materials

• Dry bulk handling

• Marine and government

Bi-directional sealing

Integral flange seal

ASME Class 150 rating

This valve provides bi-directional

sealing at full rated pressure with

identical flow from either direction.

Molded into the edge of the seat is

an integral flange seal which

accommodates ASME weld neck,

slip-on, threaded and socket flanges

as well as “stub end” type C flanges.

Body rating is ASME Class 150

(285 psi non-shock).

Wafer body diameters are designed

to self-center in ASME Class 150

flange patterns.

BUTTERFLY VALVES

FEATURES AND BENEFITS

Multiple pressure ratings

Three drop tight pressure ratings are

offered for 2 in. to 12 in. (50 mm to

300 mm) sizes.

The standard shut off pressure rating

is 200 psi, but 285 and 50 psi shut off

ratings are also available and where

drop tight closure is not required and

minimal torque is desired, a throttling

rated valve is available.

Both the 50 psi and throttling ratings

allow for smaller actuators, which can

significantly reduce overall installation

cost in automated applications.

The 14 in. to 36 in. (350 mm to

900 mm) size valves are available in

150 and 50 psi drop tight shut off

ratings as well as throttling.

Dry stem journal eliminates

potential for leakage

Hard-backed cartridge seat

The DEMCO disc is uniquely designed

with a continuous annular raised land

around the stem hole and disc edge

which presses into the seat flat at every

angular position. The resilient seat

presses back with a higher specific

force than the line pressure, preventing

leakage to the stem. In addition, two

O-ring ribs are provided in the seat

stem bore creating a triple stem seal.

In competitive stem seal designs with

boot seats, a seal is accomplished by

an interference “squeezing” on the

stem or an O-ring in the stem journal.

The potential for leakage behind the

seat is high for this competitive design.

As the disc wipes the seat, elongation

of the stem seal area allows leakage

to collect behind the seat. This

condition is eliminated by DEMCO’s

dry stem journal and hard-backed seat.

The DEMCO cartridge seat is

constructed by permanently bonding

a resilient elastomer to a rigid backing

ring. In addition to superior sealing

integrity, this design; 1) makes valve

installation easier because no special

precautions are required for disc

position. This is especially

advantageous when installing valves

with fail closed actuators; 2) eliminates

high torque and premature failure

caused by elastomer distortion as

found in other non-rigid seat designs;

3) simplifies seat replacement because

it is slip fitted into the body, with no

need for special tools.

Positively oriented disc

End-of-line service

Proper orientation of the stem/disc

connection is assured by the

rectangular drive. In 2 in. through

24 in. (50 mm through 600 mm)

size valves, the disc is permitted to

float on the stem to perfectly

center in the valve seat. This design

enhances drop tight sealing and

prolongs service life.

Lug body valves may be used in

end-of-line service, with downstream

piping removed. (Only weld neck or

socket flanges can be used for this

service). Since upstream pressure is

excluded between the flange and

the seat face by the exclusive

DEMCO flange seal design, there is

no effective force to slide the seat

downstream.

DEMCO 2 in. through 12 in. (50 mm

through 300 mm) Lug Butterfly

Valves are suitable for liquid service

up to 200 psi with downstream

piping removed (150 psi 14 in.

through 36 in.

(350 mm through 900 mm)).

Lug body valves are recommended

for isolation of pumps, control

devices or other system components

which may need to be removed for

repair or replacement.

Lug valves are also suitable for

installation at points from which

piping expansion may proceed.

Such valves are normally blanked

with blind flanges, to protect the

exposed seats until new piping is

attached.

BUTTERFLY VALVES

Series NE-I Sanitary

Other benefits:

Sizes 2 in. through 12 in. (50 mm through

300 mm), it is similar to our Series NE-I valve,

but is exclusively designed to meet the

rigorous requirements of sanitary service in

the food and beverage industry. The body is

available in bronze, stainless steel, aluminum

or electroless nickel-coated ductile iron.

FDA - approved materials are used for all

wetted parts. Handle parts are bronze and

stainless steel, permitting caustic washdown.

• DEMCO dry journal stem seal system gives

absolute assurance of sanitary butterfly

valve construction.

• Drilled passageways, a design originated by

DEMCO, vent the entire interior of the disc to

atmosphere. No closed chamber is provided

for the culture of undesirable organisms.

• Discs are produced from investment castings,

smooth and non-porous. Stem bosses are

minimized for increased flow.

• The projecting inner surface of the resilient

seat contacts and is compressed by the

mating flange to form a smooth and

uninterrupted flow way.

This positive seal between the innermost

contact of the seat and flange ensure aseptic

conditions after a piping flush.

Sanitary Features

Series NEI-T Teflon

Marine

Because of the inert, aseptic non-stick character

of Teflon, DEMCO’s NEI-T Teflon-lined butterfly

valve is ideal for “clean” lines in food and

beverage plants.

The Teflon seat consists of a virgin Teflon liner

overlaying and bonded to an elastomer cushion

(either Buna-N or EPT are available) which

provides resilience for sealing.

The Teflon liner extends over the seat faces,

completely covering and sealing the resilient

material from contact with line fluids.

DEMCO Marine butterfly valves are available

in the NE-C Lug, NE-I Lug and Wafer and NE-D

Wafer styles and conform to Title 46 of the

Code of Federal Regulations, Part 56 of the

U.S. Coast Guard’s Marine Engineering

Regulations as well as the American Bureau of

Shipping Standard including tagging per

MSS-SP-25 and testing per MSS-SP-67.

BUTTERFLY VALVES

DR PISTON ACTUATORS

DEMCO Series DR Piston Actuators consist of two opposed

pistons with integral gear racks which are coupled to a

common central drive shaft to produce rotary motion.

In the basic unit, the Body, Pistons and End Caps are

aluminum; the Central Drive Shaft is hard anodized, high

performance Aluminum Alloy 70-75. The Fasteners are

plated steel; the Seals are Buna-N. All units are totally

enclosed and use gaskets for weatherproof operation.

Carbon filled teflon guide bands support the pistons to

eliminate metal-to-metal contact during actuator operation.

As a result, piston O-rings designed for sealing are not

required to perform bearing functions.

Mounting the actuator to the valve for many popular sizes

is direct, requiring only a splined, aluminum stem adapter.

Other sizes may require the addition of an aluminum

adapter plate, but still make a closed coupled unit.

Some sizes (mostly the larger valves) will require the

traditional steel brackets/coupling mounting kit.

Consult the factory for complete data sheets showing

mounting configurations. Flatted stems are standard on

2 in. through 12 in. (50 mm through 300 mm) Butterfly

Valves (NE-C, NE-I, NE-D), whereas 14 in. through 36 in.

(350 mm through 900 mm) NF-C utilize a keyed stem.

Series DR Actuators are available as Double-Acting or

Spring Return. Double-Acting is the most economical,

requiring either air or hydraulic pressure for opening

and closing (fail last position).

Spring-Return Actuators

use compression spring(s)

to move valve in one

direction, while air

pressure moves it in

the opposite direction.

Spring Return Actuators

are used when valves

must move to a

predetermined position

upon air supply failure

(fail open or fail closed).

Position Indicator Switches*

Positioners*

Solenoid Valves*

Position Indicator Switches are available

toprovide an electrical contact closure at

open and closed positions, normally used

for On-Off service.

Independently adjustable SPDT switch

elements are arranged so that each end

of the valve travel is indicated by separate

circuit closures.

Pneumatic positioners are offered for

modulating service. The standard signal

range is 3-15 psi, and may be

generated by temperature,

pressure or level controllers.

Solenoid Valves are used to

direct supply air to the actuator

to open and close the butterfly

valve at the command of an on/off

electrical signal.

Direct attachment to the actuator through

a manifold eliminates all external piping.

Pressure connections are 1/4 NPT. Standard

voltage is 120 VAC; other voltages are

available on special order.

NEMA 4 weather proof or NEMA 7 explosion-

proof enclosures are available.

Solenoid valves are available as 3-way valves

for spring return actuators or 4-way for double

acting actuators. Four-way solenoids are

equipped with a push button manual override.

Exhaust metering valves are available to

control opening and closing speed of

the butterfly valve.

Declutchable Manual

Worm Gear Overrides

are available for size

40 through 4004 DR actuators.

Especially applicable to spring return actuators,

the handwheel can be engaged with a special

declutch lever to hold the valve in its last

position until the actuator is

returned to automatic operation.

Seal Kits consist of all

rubber seals, bushings

and guide bands required

to repair either double acting

or spring return actuators.

BUTTERFLY VALVES

GENERAL TECHNICAL INFORMATION

Pressure Rating

Vacuum Rating

End-of-Line Service

Three drop tight pressure ratings are offered for DEMCO

Butterfly Valves. Normally, 200 psi shutoff is used in

butterfly applications. However, 285 psi shutoff is

optionally available for higher pressure applications.

For smaller actuator sizing, 50 psi valves offer reduced

torque.

For throttling valves, which do not

provide drop tight closure, are available.

DEMCO Butterfly Valves will seal against

(29.9 inches of mercury). For reduced torque and

extended seat life, 50 psi discs are recommended for the

dry service conditions found in many vacuum applications.

Lug body valves may be used in end-of-line service, with

downstream piping removed.

Since upstream

pressure is excluded between the flange and the seat face

by the exclusive DEMCO flange seal, there is no effective

force to slide the seat downstream. DEMCO Lug Butterfly

Valves are recommended for service up to 200 psi

with downstream piping removed.

Lug body valves are recommended for isolation of pumps,

control devices or other system components which may

need to be removed for repair or replacement.

Lug valves are also suitable for installation at points from

which piping expansions may proceed. Such valves are

normally blanked with blind flanges, to protect the

exposed seats, until new piping is attached.

Marking

Actuation

Installation and Maintenance

Each valve is positively identified by marking and tagging

per MSS SP 25.

Positive latch handles, worm gear operators and automatic

actuators are available and totally interchangeable on the

DEMCO valve.

The DEMCO top flange is dimensionally compatible with

other competitive butterfly valves. With optional “utility

top” stem, the DEMCO valve interchanges directly with

competitive valves, allowing valve replacement without

the need for new actuation.

DEMCO Butterfly Valves are bi-directional, with identical

flow-way from either face. To install, simply close the

valve, insert between flanges and make up with studs or

cap screws. No regular maintenance or lubrication is ever

required. Disassembly is simple, for inspection or

replacement of parts.

Open the valve, remove handle or actuator, remove

tangential pins, pull out the stems and push the disc and

seat out of the body. Reassemble in reverse order, with a

small amount of general purpose non-hydrocarbon based

lubricant on the outside of stems, seat and disc flats.

Steel or cast iron flanges of either raised or flat-faced type

are suitable for use with DEMCO Butterfly Valves. Plastic

flanges are subject to damage at installation by over-

tightening the bolting and may deflect or “cup,” resulting

in flange leaks. Refer proposed plastic flange installations

to DEMCO Valve Quotations Department for review and

recommendation.

Throttling discs, with no seat interference, do not provide

a stem seal. Stem O-rings are provided for this application.

Flange gaskets assist the O-rings in 2 in. through 12 in.

(50 mm through 300 mm) valves, and must be used with

throttling discs, only.

BUTTERFLY VALVES


This nomograph gives corresponding

values for the parameters of flow

rate, valve size, disc angle and

pressure drop of DEMCO Butterfly

Valves in 1.0 specific gravity water

service at 68°F (20°C).

The lower right-hand corner of the

graph with heavy line border

represents line velocities below

15 feet per second and is normally

used for valve sizing in liquid

applications.

Butterfly Valves are economical

throttling devices. Reliable

throttling can be attained at disc

openings from 25° to 70°.

Water, with specific gravity of

1.0 and flow rate of 1200 gpm,

through 6 in. (160 mm) Butterfly

Valve.

Required: Pressure drop at full and

75° disc opening.

Project horizontally from 1200 gpm

to 6 in. (150 mm) valve curve.

Project vertically upward to full

open valve curve, then horizontally

to read 0.35 psi pressure drop.

Continue upward projection to

intersect 75° opening curve, then

horizontally to read 0.8 psi pressure

drop.

Air, with density of 0.217 lbs./cu. ft.,

flow rate of 40,000 cu. ft./hr.,

through 5 in. (125 mm) Butterfly

Valve.

Required: Pres-sure drop through

full open valve.

Disregarding change in gas

condition by pressure drop across

valve, proceed from

40,000 cu. ft./hr., as in liquid

computation, to read

15 psi pressure drop.

Convert pressure drop from water

to air by multiplying this value

times the ratio of

air-to-water densities:

To determine pressure drop for any

fluid, multiply value obtained from

the nomograph by the quotient

of the fluid density, in pounds per

cubic foot, divided by 62.4.

Water Hammer

Water hammer is a series of shocks in a piping system

caused by rapidly stopping the flow of fluid in that system.

Although it is difficult to measure pressure spikes caused

by water hammer shock with ordinary equipment,

maximum obtainable pressures caused by instantaneous

valve closure can be approximated by the following

formula:

Pressure (max) = Interrupted velocity (fps) x 58 psi/fps

In other words, pressure increases 58 psi for each foot per

second of interrupted pipe line velocity.

A pipe carrying fluid at 15 feet per second velocity will

have an instantaneous pressure increase of 870 psi under

rapid closure conditions.

The effects of water hammer are seen in a butterfly valve

as bent disc and stems, broken bodies or both.

Water hammer can be minimized or eliminated by slowing

valve closure time in accordance with the following

formula:

Time seconds =

Where:

Q = Flow in gpm.

S = Upstream pipe size in sq. ft.

P = Pressure rating of the valve in psi.

Generally, a closing time of 6 to 8 seconds is sufficient to

eliminate water hammer.

Cavitation Data

Liquid flow is accelerated as it passes through a valve in such

a manner that pressure is decreased below the vapor

pressure and bubbles form. Immediately downstream of the

valve, velocity decreases while pressure increases and the

bubbles collapse causing noise and possible mechanical

damage to the valve and piping. This is called cavitation.

Cavitation can often be identified by the noise of the

collapsing bubbles which sounds like gravel flowing in the

pipe.

Generally butterfly valves operate with high flow capacities

and at low pressure differentials and are not particularly

susceptible to cavitation.

When butterfly valves are used as control valves, one can

assure that cavitation will not occur by applying the

following simplified formula:


Pmax = K (P�

C 1- P )

V

Where:

� Pmax = Differential pressure across the valve.

K = Cavitation constant

(approximately .35 for butterfly valves).

P = Inlet pressure (psia).

P = Vapor pressure of the flowing liquid (psia).

C

1

V

Example:

What is the maximum pressure drop possible through a

butterfly valve at 100 psig inlet pressure with water at

68°F (.339 psia vapor pressure)?

Pmax = K (P�

C 1- P )

V

Under the above conditions it is possible to take a 40.03 psi

pressure drop across the valve before cavitation will begin.

Torque

The torque (turning effort) required to operate a given

butterfly valve is determined by two factors: friction of

disc and seat due to interference, and dynamic forces of

flow through the valve which tend to open or close the

valve. Actuator torque output must meet or exceed the

maximum torque requirement of the valve.

Normal Wet Opening Torque requirements due to

interference are tabulated below. Dry service will

increase opening torque significantly. Consult factory for

dry service torque requirements

The disc of a butterfly valve, in partially opened

condition, is subject to “lift” forces from passage of fluid

over its surfaces. This effect is analogous to an airplane

wing and results in an unbalanced turning force on the

disc. Dynamic torque is proportional to pressure drop

through the valve and may become significant in some

applications.

Dynamic torque typically is a maximum at about 70° disc

opening. Under high differential pressure conditions,

such torque may exceed the design strength of stems,

connections or actuators. The curves at right may be used

to calculate dynamic torque for DEMCO Butterfly Valves

and should be consulted in any case where high

differential pressure may occur during operation of a

valve.

is a general purpose elastomer compounded for

maximum hydrocarbon or petroleum resistance.

0°F to+180°F

is recommended for water service. Resistance

to saturated steam to 275°F is excellent. EPT is suitable in alkaline

solutions. EPT is not suitable for oil or hydrocarbons.

Peroxide cured +20°F to +275°F

is formulated in compliance with FDA guidelines

published in the Code of Federal Regulations, Title 21, paragraph

177.2600. This material is suitable for food service, except milk

and edible oils. Peroxide cured +20°F to +275°F

Sulfur cured -30°F to +225°F

complies with FDA guidelines and is principally

recommended for food and beverage service. It is resistant to

vegetable oils, brine and oxygen.

0°F to +180°F

offers chemical resistance comparable to black

neoprene but uses fillers other than carbon black to provide

white coloration. Physical properties are not as good as black

neoprene, and white neoprene should be used only when black

cannot be tolerated. Storage should be under low light

conditions to prevent discoloration. 0°F to +180°F

is compounded for chemical resistance and is

excellent in acids and hydrocarbons.

0°F to +180°F

is excellent at elevated temperatures and also in harsh

chemical environments. Viton is not suitable for hot water or

steam. +20°F to +300°F

is generally superior to other elastomers in

abrasion resistance and is recommended for dry material

handling. Use in oils and solvents is not recommended.

-30°F to +150°F

seats offer heat and chemical resistance to

hydrocarbons and hot water or saturated steam. Maximum

temperature capability is dependent on fluid resistance,

pressure and flow rates. +20°F to +275°F

is compounded to combine many of the better

media properties of Buna-N, EPT or Neoprene for service in

hydrocarbons, gasoline, solvents, animal oils and vegetable

oils with a wide temperature range (–30°F to 230°F). Abrasion

resistance is equal to Buna-N. Resistance to hydrogen sulfide

and carbon dioxide are superior to Buna-N. -30°F to +230°F

is Buna-N, or EPT elastomer bonded to

a virgin TFE covering providing an inert, aseptic non-stick

surface which is excellent for sanitary food service

applications. 0°F to +250°F

MATERIAL SELECTION GUIDE

The following application data is for use in determining the available material most likely to give satisfactory service and

is not meant to imply any type warranty. However, certain factors such as temperature, concentration and combinations

of chemicals may affect the fluid resistance of any material. In questionable applications, testing is always the most

positive way to determine suitability. Some materials are available in certain valve sizes and series only.

TERMS AND CONDITIONS

1. CONTRACT ACCEPTANCE:

2. QUOTATIONS AND PRICES:

3. TAXES:

4. SHIPPING SCHEDULE AND DELIVERY:

Any written or oral purchase order received

from Buyer by Cooper Cameron Corporation,

Cameron Division and Cooper Cameron Valves

("Seller”) shall be construed as a written

acceptance of Seller's offer to sell and shall be

filled in accordance with the terms and conditions

of sale set forth herein. SELLER'S ACCEPTANCE OF

THIS ORDER IS EXPRESSLY CONDITIONED ON

BUYER'S ASSENT TO THE TERMS CONTAINED

HEREIN. The terms and conditions of Seller's

proposal (if any) and acknowledgement shall

prevail over any conflicting or different terms in

Buyer's order unless Buyer notifies Seller in writing

of its objections thereto within fifteen (15) days

from receipt of Seller's acknowledgement. Buyer's

standard terms of purchase will not be considered

a counteroffer to Seller's terms and conditions of

sale. The failure of Seller to object to any provision

in conflict herewith whether contained on Buyer's

purchase order or otherwise shall not be

construed as a waiver of the provisions hereof

nor as an acceptance thereof.

All quotations are made for prompt acceptance

and any terms quoted therein are subject to

change without notice after thirty (30) days from

the date quoted unless specifically stated

otherwise on the quotation. Any product, service

capability or manufacturing capability which may

be available at the time a quotation is made is

subject to prior sale. Prices quoted are valid for

thirty (30) days unless specifically stated otherwise

on the quotation and are subject to change

without notice. The price in effect at the time of

shipment including any escalation formula will

apply, unless a valid quotation or written

agreement to the contrary exists between Buyer

and Seller. All prices shown are in U.S. dollars

and are F.O.B. Seller‘s shipping point.

Any documentation pertaining to traceability

requirements for raw materials or products or

documentation required for any routine or

special processes must be identified by the Buyer

at the time of quotation (if any) or at the time of

order placement

Any tax or other charge imposed by law on the

sale or production of goods or the performance

of services shall be paid by the Buyer, unless the

law specifically provides that such payment must

be made by Seller, in which case Buyer shall

reimburse Seller for such payment as part of the

purchase price. Custom duties, consular fees,

insurance charges and other comparable charges

will be borne by Buyer.

Shipment schedules are given as accurately as

conditions permit and every effort will be made

to make shipments as scheduled. Seller will not

be responsible for deviations in meeting shipping

schedules nor for any losses or damages to Buyer

(or any third party) occasioned by deviations in

the shipping schedule, whether due to Acts of

God, orders bearing priority ratings established

pursuant to law, differences with workmen, local

labor shortages, fire, flood, shortages or failure

.

of raw materials, supplies, fuel, power or

transportation, breakdown of equipment or any

other causes beyond Seller's reasonable control,

whether of similar or dissimilar nature than those

enumerated. Seller shall have additional time

within which to perform as may be reasonably

necessary under the circumstances and shall have

the right to apportion its production among its

customers in such a manner as it may consider to

be equitable.

Seller reserves the right to furnish commercially

equivalent or better substitutes for materials or

to subcontract the Buyer's order or portions

thereof as Seller deems necessary. In no event

shall Seller be liable for any consequential

damages for labor resulting from failure or

delay in shipment. If Buyer requires drawings,

procedures, standards or similar material for

approval, shipping schedules will be calculated

from the time such approvals are received by

Seller, since shipping schedules are based on

Seller having all required information and a

firm order from Buyer which is enterable into

production. Any hold points, witness points or

the need for inspection by Buyer's represent-

atives must be identified by Buyer at the time

of quotation (if any) and/or order placement in

order that the effect on the prices or shipping

schedules (if any) can be taken into account.

Additional inspection or testing required by

Buyer which affects normal production

sequence will be considered as extending

the shipping dates accordingly.

Seller reserves the right to impose a minimum

billing charge on all sales, change orders or

order supplements.

Terms of payment for all materials and service

are 30 days from invoice date, at net price,

provided satisfactory credit has been established.

All unpaid invoices are subject to the maximum

legal interest rate per annum commencing with

the due date.

Purchase orders once placed by Buyer and

accepted by Seller can be canceled only with

Seller's written consent and upon terms which

will save Seller from loss. No products may be

returned for credit or adjustment without

written permission from Seller's office

authorized to issue such permission.

All products of Seller's manufacture are

warranted against defects of material and

workmanship for a period of twelve (12)

months from the date of installation or

eighteen (18) months from date of shipment,

whichever period first expires, when such

products are used in the service and within

the pressure range for which they were

manufactured. In the case of products or parts

not wholly of Seller's manufacture, Seller's

liability shall be limited to the extent of its

recovery from the manufacturer of such

products or parts under its liability to Seller.

5. MINIMUM BILLING:

6. TERMS OF PAYMENT:

7. CANCELLATIONS AND RETURNS:

8. WARRANTIES:

Any repair work performed by Seller is warranted

for one year from completion of such repairs and

applies only to work performed.

If, within these specified periods, Seller receives

notice from Buyer of any alleged defect in or

nonconformance of any product or repair and if,

in the Seller's sole judgment, the product or repair

does not conform or is found to be defective in

material or workmanship, then, Buyer shall, at

Seller's request, return the part or product F.O.B.

to Seller's designated plant or service location.

Seller has no liability for removal or reinstallation

of products or equipment from below the surface

of the water. Seller, at its option and expense,

shall repair or replace the defective part or product,

or repay to Buyer the full price paid by Buyer for

such defective part, repair or product. Any

repayment of purchase price shall be without

interest.

Seller's warranty liability, including defects

caused by Seller's negligence, shall be limited to

such repair, replacement or refund, and shall not

include claims for labor costs, expenses of Buyer

resulting from such defects, recovery under general

tort law or strict liability or for damages resulting

from delays, loss of use, or other direct, indirect,

incidental or consequential damages of any kind.

Seller will not be responsible for failures of products

which have been in any way tampered with or

altered by anyone other than an authorized

representative of Seller, failures due to lack of

compliance with recommended maintenance

procedures or products which have been repaired

or altered in such a way (in Seller's judgment) as to

affect the products adversely. THIS WARRANTY IS

EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES,

EXPRESS, STATUTORY OR IMPLIED, INCLUDING THE

WARRANTY OF MERCHANTABILITY AND FITNESS

FOR PARTICULAR PURPOSE WHICH EXCEED

THE FOREGOING WARRANTY.

The products sold hereunder are not designed or

manufactured for use in or with any atomic

installation or activity. If the Buyer or ultimate

user of these products intends to use them in such

an installation or activity, Seller's Nuclear Terms of

Sale shall be part of and control this contract.

Seller will furnish Buyer with a copy of its Nuclear

Terms of Sale upon request.

Seller warrants that the use or sale of material

or apparatus sold or rented by it to Buyer

hereunder will not infringe United States' patents

of others covering such material or apparatus by

itself, and hereby agrees to indemnify Buyer against

judgment for damages for such infringement of

any such patent, provided that Buyer shall, upon

receipt of any claim for infringement of any such

patent or threat of suit for such infringement or

upon the filing of any suit for infringement, which-

ever comes first, promptly notify Seller in writing

and afford Seller full opportunity, at its option and

its own expense, to answer such claim or threat

of suit, assume the control of the defense of said

suit, and settle or compromise same in any way

Seller sees fit. Other than court-awarded

judgments as aforesaid Seller shall not be liable

for any delays, loss of use or for other direct,

indirect, incidental or consequential damages

incurred by reason of any such judgment. Seller

does not warrant that such material or

apparatus (a) will not infringe any such patent

when not manufactured by or for Seller or when

specially made in whole or in part to the Buyer's

design specification and such infringement arises

from the inclusion of such specified design or (b),

if used or sold in combination with other

material or apparatus, or if used in the practice

of a process, will not, as a result of such

combination or use, infringe any patent covering

such combination or process; and Seller shall not

be liable for and does not indemnify Buyer for

damages or losses of any nature whatsoever

resulting from actual or alleged patent

infringement arising pursuant to (a) or (b)

above.

Seller in its sole discretion shall have the right

to manufacture the products provided

hereunder as far in advance of its estimated

shipping schedule as it deems appropriate. Seller

expressly reserves the right to change or modify

the design and construction of any product in

due course of Seller's manufacturing procedure

without incurring any obligation or liability to

furnish or install such changes, modifications or

improvements to products previously or

subsequently sold.

Upon request, Seller will provide engineering

and/or technical information regarding its

products and their uses and if feasible, will

provide personnel to assist Buyer in effecting

field installations and/or field service. Any such

information, service or assistance so provided,

whether with or without charge, shall be

advisory only. In that regard, neither Seller nor

Buyer assumes any liability for the acts or

omissions of the other party except as may be

provided in these terms.

Seller hereby certifies that these products were

produced in accordance with all applicable

requirements of Section 6, 7 and 12 of the

Fair Labor Standards Act as amended and of

regulations and orders of the United States

Department of Labor issued under Section 14

thereof.

Unless otherwise agreed in writing, final

inspection and acceptance of products must be

made at Seller's plant or other shipping or

receiving point designated by Seller and shall

be conclusive except as regards latent defects.

Buyer's representatives may inspect at the

Seller's plant or shipping point during working

hours prior to shipment in such manner as will

not interfere with operations.

Delivery shall be in accordance with the

requirements in the Purchase Contract, provided,

in the event Buyer is unable to accept delivery

upon completion of the manufacture of the

Goods in accordance with such requirements,

11. SELLER'S RIGHT TO MANUFACTURE:

12. ENGINEERING AND SERVICE:

13. LABOR STANDARDS:

14. INSPECTION:

15. DELIVERY AND ACCEPTANCE:

Buyer agrees that (i) title and risk of ownership

shall pass to Buyer on date of Seller's invoice and

(ii) Buyer will make payments within thirty days

after date of such invoice. Seller shall retain

custodial risk of loss until delivery is made in

accordance with such requirements.

All prices are F.O.B. Seller's plant or other

designated shipping point.

No freight is allowed unless stated in Seller's

quotation (if any) or in a written contract which

may exist between Seller and Buyer at the time

of shipment. If Seller's quotation or a written

contract states that all or a portion of freight is

allowed, all prices are F.O.B. Seller's plant or

other designated shipping point, with most

economical surface transportation allowed. If

the quoted or contractual price includes

transportation, Seller reserves the right to

designate the common carrier and to ship in the

manner it deems most economical. Added costs

due to special routing requested by the Buyer

are chargeable to the Buyer. Under no

circumstances is any freight allowance which is

absorbed by Seller to be deducted from the

selling price. If the quoted price or contract

includes transportation, no deduction will be

made in lieu thereof whether Buyer accepts

shipment at plant, warehouse, freight station,

or otherwise supplies its own transportation.

When sales are made from the Seller's

warehouse, Seller reserves the right to charge

either actual or pro-rated freight from Seller's

principle point of manufacture to Seller's

warehouse. Buyer assumes risk of loss upon

delivery to the carrier, regardless of who pays

shipping costs.

Seller endeavors to pack or prepare all

shipments so that they will not break, rust or

deteriorate in transit, but does not guarantee

against such damage. Unless requested in

writing by the Buyer, no shipments are insured

by Seller against damage or loss in transit. Seller

will place insurance as nearly as possible in

accordance with Buyer's written instructions but

in such case Seller acts only as agent between

the insurance company and the Buyer and

assumes no liability whatsoever.

Any claims for shipping loss, breakage or

damage (obvious or concealed) are Buyer's

responsibility and should be made to the carrier.

All claims regarding shortages must be made

within thirty (30) days from receipt of shipment

and must be accompanied by the packing list(s)

covering the shipment.

Consular fees for legalizing invoices, stamping

bills of lading, or other documents required

by the laws of any country or destination are

not included in quotations or selling prices.

If instructed in writing, Seller will make

arrangements for consular documents and

declarations as agent of the Buyer, but Seller

assumes no liability whatsoever as a result of

making such arrangements. Seller assumes no

responsibility for any fines or other charges

imposed due to errors or incorrect declarations.

19. MODIFICATION, RESCISSION & WAIVER:

A. INDEMNIFICATION:

Seller agrees to indemnify Buyer and hold Buyer

harmless against any claims, demands or causes

of action for property damage or personal injury

(including death) caused by the negligent act or

omission of any employee, agent or sub-

contractor of Seller and not contributed to by

the negligence of Buyer, its employees, its agents

or any third party. Seller shall not be responsible

for the acts and workmanship of employees,

agents, contractors or subcontractors of Buyer

or any third party, nor for failure or malfunction

of any tools, materials, equipment, products,

supplies, facilities or devices not manufactured

and supplied by Seller. Buyer agrees to hold

Seller harmless from any and all losses, claims,

or damages arising from subsurface damage,

parties that this indemnity shall apply to

INSTALLATION, SYSTEM OR FACILITY INTO

WHICH SELLER'S EQUIPMENT MAY BE LOCATED

OR AT WHICH SELLER, ITS AGENT OR

SUBCONTRACTOR MAY BE PERFORMING WORK.

Seller's total responsibility for any claims,

damages, losses or liabilities arising out of or

related to its performance of this contract or

the products or services covered hereunder shall

not exceed the purchase price.

The terms herein may not be modified or

rescinded nor any of its provisions waived unless

such modification, rescission or waiver is in

writing and signed by an authorized employee

of Seller at its office in Houston, Texas.

Failure of Seller to insist in anyone or more

instances upon the performance of any of the

terms and conditions of the contract or the

failure of Seller to exercise any of its rights

hereunder shall not be construed as a waiver

or relinquishment of any such term, condition,

or right hereunder and shall not affect Seller's

right to insist upon strict performance and

compliance with regard to any unexecuted

portions of this contract or future performance

of these terms and conditions.

All orders must be accepted by an authorized

employee of Seller. The rights and duties of the

parties and construction and effect of all

provisions hereof shall be governed by and

construed according to the internal laws of the

State of Texas. Any disputes which arise under

this agreement shall be venued in the District

Court of Harris County, Texas or in the Southern
