Gate valve

· Design

Cast steel gate valves are designed and manufactured to provide maximum service life and dependability.

All gate valves are full ported and meet the design requirements of American Petroleum Institute standard AP1600&API 6D, British standard BS1414&BS EN 1984 and generally,conform to American Society of Mechanical Engineers standard ASME B16.34.

Valves are available in a complete range of body/bonnet materials and trims.

· Ranges of materials

Standard body/bonnet materials include nine grades of carbon, low alloy and stainless steels. 

For special applications they can be supplied in other grades of alloy and stainless steel. 

There’s a full range of trim materials to match any service.optional packing and gasket materials are available for a full range of service conditions.

Operation Live Load Packing OS&Y BB End Connections
Large handwheels for easy operation.also avaliable with gearing.motor actuators, pneumatic or hydraulic actuators for more difficult services. In services requiring frequent cycling or withhighpressure/temperature variations,live loading extends the service life between maintenance periods byrequiring less stments. Belleville springs are employed to provide constant packing gland stress. Outside screw and yoke. Cast steel gate valve yoke integral with bonnet for 150Lb-8", 600Lb-6", 900Lb-4"&small. Welding bonnet and pressure seal bonnet in services requiring frequent cycling or with high pressure/temperature variations. A choice of flanged, RTJ flanged or buttwelding end for piping flexibility.
Yoke sleeve Lantern Ring And Double Packing Set Body-to-Bonnet Joint Stem Wedge
Extra long thread engagement between yoke sleeve and stem provide long thread life. Valves of sizes larger than 150Lb-12", 300Lb-10",600Lb-6", 900Lb/1500Lb/2500Lb-4" are regularly provided with roll bearing yokes. lantern ring with leak-off fitting connection and double packing stack is optionally avaliable for critical services. A flat face gasket joint is used in the
150lb valves. A male and female joint
is used in 30olb to 60olb valves.ring
joint is used in the body to bonnet
connections in 90olb & higher
rated valves.		 All wedge gate valves are provided with upset forged T-head stems. By forging the T-head,the stem at the stem-wedge connection is stregthened,this design also allows the wedge possibility of a bent stem jamming the wedge. Integral guide rib faces assure self-centering of wedge. Flexible wedge gate valve has a one- piece, twin-disc wedge, which is designed so that each half flexes independently. Avaliable in solid, flex split and his designs.
