Weco Butterfly Valves and Actuators

BV1

Choice of operators, actuatorsAll Weco butterfly valve models canbe equipped with a wide range ofoperators and actuators.

Weco butterfly valves offer the ultimate in dependable, economical flow control.These field-proven valves are available from stock in 2 through 24-inch sizes andcan handle working pressures up to 175 psi. For pressure ratings from 176 psi upto 285 psi, consult factory. Wafer, notched, and lug-type body styles meetrequirements for new or existing flowline systems. Using a variety of materials,valve bodies, discs, stems, and seats can be individually matched to specificoperating conditions, including temperature range, type and concentration offluid, and various flow conditions. All materials meet ASTM and AISI standards.

Outstanding flow efficiencyStreamlined disc design minimizesturbulence and pressure drop forgreater flow efficiency.

Leak-proof installationRibbed seat face eliminates theneed for flange gaskets andensures leak-proof installation.

Fast, simple field repairIf a valve should need repair, itcan be completely reconditionedin the field using interchangeablestock parts.

Triple seal designAn O-ring, unders ized stem holesin the seat, and correspondingflats on seat and disc hubs providethree completely independentseals. This unique feature isolatesboth the upper and lower stemsfrom line fluid, allowing use ofstandard stem material.

Elastomer seatAn elastomer seat with two-piece,hard phenolic back-up eliminatesseat walking and allows the seatto expand under pressure, makingthe valve body the pressure con-taining component.

Self-centering discDual stem with upper and lowertangential pins allows a self-centering disc. This designprovides equal sealing pressure360 around the disc, ensuringpositive shut off and extendingservice life.

No in-line pins, screws or boltsHex drive provides positive discmovement without in-line pins, screws,or bolts.

Weco Actuator Sizing Information

Actuator Sizing Information

Required Operating Torques:

There are three torques to be considered when selectingthe proper actuator for a butterfly valve:

(1) Seating Torque - The torque required todisplace a resilient seat and effect shutoff

(2) Bearing Torque - The torque required toovercome friction forces on the valve shaftbearing surfaces

(3) Dynamic Torque - Torque due to fluid forceswhich tend to close the valve.

The torques for resilient seated valves tabulated in thissection are the sum of (1) and (2) above for various shut-off pressures. These tabulated values include a safetyfactor large enough to insure proper valve operation inmost general butterfly valve applications. Where unusualservice conditions exist (such as likelihood of seat swell-ing, or low and high temperature seat hardening), anadditional safety factor may be applicable.

Dynamic Torque

Dynamic torque is torque on the valve shaft due to thefluid forces on the valve disc. This torque is a function ofvalve diameter, pressure drop, and a torque coefficient(Ct) which varies with angle opening. Torque is calculatedby the equation:

T = CtD3P Where: T = Dynamic torque (in-lb)

D = Valve Dia. (in.)C

t= Dynamic torque coefficient

Weco Actuator Sizing Information

Actuators Sizing Torque for Weco Butterfly Valves

Dynamic torque is not usually of major concern inresilient seated butterfly valves unless the line velocityexceeds 20 fps. If line velocity exceeds this, a checkshould be made to insure that actuator output exceedsthe calculated dynamic torque. Dynamic torque shouldbe checked at 80 open for on-off applications.

Dynamic torque is of prime consideration in situationswhere line velocity is not recovered downstream of thevalve. This situation exists on installations where thereis an unlimited source and less than 6 diameters of pipedownstream of the valve. If a valve discharges to the

atmosphere, the pressure drop across the valve will beequal to the height of water above the valve for all anglesof valve opening. This pressure drop must not exceedthe pressure drop tabulated in Maximum P vs. Angle

Opening Tables for any angle. If it does, provisions mustbe made for velocity recovery by adding downstreampiping.

Actuator Sizing For Tee LinkagesFor standard tee linkage applications where oneactuator operates two butterfly valves of the same sizewith one valve opening as the other valve closes, theactuator sizing will be the same as for a single butterflyvalve application. For the actuator sizing for othertandem linkage applications, consult the factory.

Low-Torque ValvesUndercut discs are available for butterfly valve applica-tions that require lower seating torques. For completeinformation, consult factory.

Warnings and Cautions

FMC Technologies cannot anticipate all of the situations a user may encounter while installing and

using FMC products. Therefore, the user of FMC products MUST know and follow all applicable industryspecifications and practices on the safe installation and use of these products. For additional safetyinformation, refer to FMC Technologies product catalogs, product brochures, and installation, operating,and maintenance manuals, which can be accessed at www.fmctechnologies/fluidcontrol.com, orcontact FMC Technologies at 800-772-8582.

Failure to follow these safety warnings could result in death, serious personal injury, and/or severe property damage.

Never mix or assemble components, parts, or end connections with different pressure ratings. Mismatched conditions,including but not limited to that of a 2 Figure 1502 male sub end connected to a 2 Figure 602 female sub, may failunder pressure resulting in death, serious personal injury, or severe property damage.

Never use or substitute non FMC components or parts in FMC products or assemblies.

Never modify or repair FMC products in a manner not specifically directed in instructions published by FMCTechnologies.

Never strike, tighten, loosen, or attempt repairs on pressurized components or connections.

Never exceed the rated working pressure of the product.

Complete and proper make-up of components and connections is required to attain rated working pressure. Alwaysapply essential care, attention, handling, and inspection to threaded components before, during and after make-up.

Never use severely worn, eroded, or corroded products. Contact FMC Technologies for more information on how toidentify the limits of erosion and corrosion.

Never strike wing union nuts having severely flattened and extruded ears. This condition can result in flying debrisleading to serious personal injury and must immediately be addressed by either grinding off extruded material orremoving the nut from service.

Always follow safe practices when using products in overhead applications. Products not properly secured could fall.- Never exceed the load rating of lifting devices on products or lifting equipment.- Use of FMC products in suspension applications can result in over-stress conditions leading to catastrophic failure.- If externally applied loads are anticipated, consult factory.

Always follow safe practices when manually lifting and carrying products.

Always select only appropriate product and materials for the intended service:- Never expose standard service products to sour gas fluids (Refer to NACE MR-01-75). Do not interchange sour gas

with standard service components.

- Always use appropriate safety precautions when working with ferrous products in below freezing temperatures.Freezing temperatures lower the impact strength of ferrous materials.

Always follow manufacturers instructions and Material Safety Data Sheet directions when using solvents.

Always make certain that personnel and facilities are protected from residual hazardous fluids before disassembly ofany product.

Whenever leakage is detected from FMC Technologies products, remove them from service immediately to preventdeath, serious personal injury, and/or property damage.

SAFETY INSTRUCTIONS: The applications of FMC products are in working environments and systems which must beproperly designed and controlled. Safety procedures and policies MUST be clearly established by the user and followed.

Always use appropriate protective equipment.
