ASTM A182 F321 Gate Valve, API 602, 1-1/2 Inch, 1600 LB, PSB

Key Specifications / Features

The ASTM A182 F321 Gate Valve Manufacturer produces forged steel gate valves in compliance with API 602 standards. These valves are made from high-quality ASTM A182 F321 material, ensuring durability and reliability in demanding applications. With a 1-1/2 inch (DN40) size and a Class 1500 LB (PN250) pressure rating, they feature an extended body and a pressure seal bonnet design. This combination provides enhanced performance and safety, making them suitable for high-pressure systems.

Pressure Seal Gate Valves are meticulously designed and manufactured to meet International Standards API 602, ASME B16.34, DIN 3202, or their equivalents. These valves feature a compact yet exceptionally robust design, ideal for high-pressure and high-temperature applications.
An optional solid CoCr alloy wedge ensures low friction and extended service life. Packing rings are pre-compressed to 4000 psi, delivering a highly reliable seal. For welded bonnet valves, the bonnet is threaded and tightened to a precise engineered torque value, with the body-bonnet joint strength-welded to provide double protection against leakage.
The fully guided wedge minimizes wear on seating surfaces, enhancing durability. Optional features include double packing, leak-off connections, live-loading, and a packing blowout design for easy removal and replacement of packing materials.
