Detailed Product Description 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 API **0 and ASME B*6.*4. Valves are available in a complete range of body/bonnet materials and trims. DESIGN SPECIFICATIONS: Wall thickness and general valve design: API **0 Test: API **8 Pressure-temperature rating: ASME B*6.*4 Face to face dimensions for butt weld and flanged valves: ASME B*6.*0 Flange design: ASME B*6.5 Butt welding design: ASME B*6.*5 PRODUCTS RANGE: Size: 2" ~ *8" Rating: ASME **0lb ~ ***0lb Body Materials: Carbon Steel, Stainless Steel Alloy Steel, Trim: API **0 Operation: Handwheel, Gear, Motor, Pneumatic. APPLICATION: Oil, Gas, Refinery, Chemical, Petrochemical, Power plant, General Industry. DESIGN FEATURES: (1) Rising Stem - easily visible open-close indication. (2) Grease Fittings - yokesleeves equipped with fittings to minimize wear and operating torque. (3) Swing Bolts facilitate - easier maintenance and packing replacement. (4) Stuffing Box - optional lantern rings and grease injectors are available. (5) Backseat - machined bonnet stem bushing provides back-up stem seal. (6) Bonnet Joint - joint design varies with ASME class rating. (7) Body - full ported, heavy duty body with API **0 wall thickness for maximum service life. (8) Seat Rings separate heavy duty, full ported rings for easy maintenance. (9) Handwheel - large handwheels for easy operation. Also available with gearing, motor actuators, or cylinder actuators for more difficult services. (*0) Yokesleeves - furnished in ductile Ni-resist or aluminum-bronze to reduce operating torque. (*1) Gland - two-piece gland/gland flange is self-aligning to eliminate stem damage from cocked gland. (*2) Stem - all Wuyou wedge gate valves are provided with upset forged T-head stems. By forging the T-head, the stem at the stem-wedge connection is strengthen
