Detail introduction

A - Operating: Large hand-wheels for easy operation. Also available 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 service life between maintenance periods by requiring less stments. Belleville springs are employed to provide constant packing gland stress.

C - OS&Y: Outside screw and yoke. Cast steel gate valve yoke integral with bonnet for 150lb-8”, 600lb - 6”, 900lb - 4” and smaller.

D - BB: bolted bonnet, welding bonnet and pressure seal bonnet in services requiring frequent cycling or with high pressure/temperature variations.

E - End Connections: A choice of flanged, RTJ flanged or butt-welding end for piping flexibility.

G - Yoke sleeve: 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 available for critical services.

H - Body-to-Bonnet Joint: A flat face gasket joint is used in tie 150b 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.

I - Stem: 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 strengthened.this design also allows the wedge possibility of a bent stem jamming the wedge.

J - 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, available in solid, flex split and his designs.
