Oxygen & Chlorine Clearing & Packaging
Large handwheels for easy operation. alsoavaliable with gearing.motor actuators, pneumatic or hydraulic actuators for more difficult services.
|B)Live Load Packing
In services requiring frequent cycling or with high pressure/temperature variations,live loading extends the service life between maintenance periods by requiring 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.
Bolted bonnet, 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.
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.
|G)Lantern Ring And Double Packing Set
Lantern ring 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 300lb to 600lb valves.ring joint is used in the body to bonnet connections in 900lb & 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 onepiece, twin-disc wedge,which is designed so that each half flexes independently.avaliable in solid, flex split and his designs.
