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.
