9800SERIESPlastic Diaphragm Valves Fitted With Pneumatic And Electric Actuator

SUDER

CMYK

Sude offers – Imported Diaphragm valves are with one piece rugged

body having cross ribs at flanged ends. They are available in size

range of 15mm to 100mm. Its latest inverted design diaphragm

remains unstressed while valve is in close position so it gives more

service life. The Diaphragm of these valves are available with

Neoprene, EPDM, Hyplon, Butyl, PTFE-Coated and pure PTFE. The

construction of valve with pure Teflon diaphragm, MS backing ring on

bonnet and body which provide extra support and strength.

Diaphragms valves are with deep seat allow maximum flow and

excellent flow characteristics.

Plastic Diaphragm Valves are dependent on the design, especially

suitable for highly – pure to heavily contaminated, liquid and gaseous

inert and corrosive media. Just as classical control valves also have

good control properties, especially for media which is soiled or

provided with particles.

The major areas of use are the semiconductor industry and

microelectronic and a wide variety of industrial applications e.g. water

treatment.

The valve can be manually, pneumatically and as well as electrically

operated.

Optional Features & Accessories

Valves are supplied in 'Closed' condition with single acting, double acting Actuator.

Optimal: Normally 'Open' construction, Double Acting Actuator, Electro Pneumatic valve Positioner, Valve travel Indicator with

Limit switches and LED, Proximity Switch Sensors, Stroke Limiting Mechanism, Manual Override in lieu of some accessories,

Namur 3-way and 4-way Solenoid Valves and the valves is also supplied with Electrical Actuator in case of motorised, generally

supplied in on/off construction can be supplied with servo unit for modulating application.

The valve design is abrasion – resistant and non – clogging. Slurries at low pressure that would normally clog most other valve

designs easily pass through a diaphragm valve. The valve has a top entry design, allowing in – line maintenance; it is suitable

for throttling and on / off service in applications ranging from water treatment to chemical abrasion processes. Diaphragm

valves are operated Manually, Electrically, Pneumatically. Sude offers all plastic diaphragm valves have been specifically

designed to perform in the most demanding liquid, gas and slurry applications in both ON / OFF and modulating service.

Advantages

?Body and Diaphragm sizes have co-ordinate diameters hence the fitting time is reduced because the pipe and fixing centers

remain the same. Spares inventory is also reduced.

?Optional accessories

?Electrical remote indication that the valve is in the open position

?Lockable hand wheel

?Compact, weight – saving design

?Good specific flow capability

?Body with integrated mounting facility

Installation

Sude offers flanged Diaphragm valves are designed for use with all ANSI Class 150-pipe flanges. When installing flanged

Diaphragm valves dead end service, it is recommended to install between one pipe flange and a downstream blind flange.

Soft rubber flange gaskets are required.

Be sure to allow space between the mating flanges for the end-to end length of the valve plus the minimum thickness of

the flange gasket. This will allow for proper installation, without distorting the gaskets when tightening the assembly.

Use well lubricated studs or bolts and nuts. Use metal washers for plastic flanges between nut / bolt head and the flange.

Use a torque wrench to uniformly tighten nut to approximately 10 foot pounds. Use an alternate sequence, diametrically

opposed to the previously tightened nut.

Use pipe hangers based on normal manufacturer recommendations. The valve shall not support the weight of the pipe.

Repair And Maintenance:

The most common repair required for Diaphragm Valve is the replacement of the Diaphragm itself. Fluid viscosity, chemical

make-up and the frequency of cycle can affect the service life of the diaphragm.

Replacement of the Diaphragm may be performed without removal of the valve from the system. The valve should be in

the “Open” position. Remove the bonnet bolts and washers. Remove the bonnet with the Diaphragm. The Diaphragm

should be separated from the compressor and bonnet. Rotate it counterclockwise from the compressor. When installing the

new Diaphragm, be sure that the holes in the Diaphragm align with the holes in the bonnet.

SUDE 069800SERIES

Electrical Actuator

Sude offers single phase multi turn / linear actuator in two different models which is compact having stall duty motor.

A compact stall duty synchronous motor, directly mounted on the base plate of spur gear box, drives gear train. The gear

wheel of the last stage drives a special nut with trapezoidal thread, which in turn moves the non-twistable actuator stem

upwards and down wards. The Important industries such as chemical, fine chemical, pharmaceutical & others dealing with

industrial process prefer small & medium size valves.

The special nut is, contrary to common practice followed in electric actuators, not rigidly fixed to the actuator frame, but is

mounted and held in a middle position by an arrangement of spring washers. When the valve plug, connected via the valve

stem to the actuator stem by a special coupling device, reaches the seat the “floating” nut compresses continuously the

spring package and thereby steadily increases the closing force. Due to this, valve always maintains zero leakage.

The two rigid steel rods connect the actuator with the control valve bonnet and serve in addition as travel indicator and

anti-twist devices for the actuator stem. Sude actuator is always equipped with a hand wheel, which allows manual

operation of the valve in emergencies or in case of power failure.

The high grade aluminum housing tightly sealed by an O-ring, provides an excellent protection against dirt, dust and/or

water, and conforms to protection class IP65/IP67.

The Electrical Actuator has a positioner and Transmitter possible feed back, space heater to avoid water condensation,

positioner for modulating control duty applications.

Pressure / Temperature Diagram

The pressure / temperature limits are applicable for the standard nominal pressures and a computed operating life of

25 years. The values are a guide for harmless media, to which the material of the valve is resistant. The durability of wear

and tear parts depends on the operating conditions of the application.

For temperatures below 0°C (PP < +10°C) please specify the precise operating conditions. Refer figure pressure /

temperature diagram.
