Pressure Seal Gate Valves are meticulously designed and manufactured in strict adherence to international standards such as API 602, ASME B16.34, DIN 3202, or their equivalents. These valves feature a compact yet extremely robust design, making them suitable for high-pressure and high-temperature applications. The optional solid CoCr alloy wedge ensures low friction and extended service life. The packing rings are precompressed to 4000 psi, providing a high-integrity seal. For welded bonnet valves, the bonnet is threaded in and torqued to an engineered torque value, and the body-bonnet joint is strength-welded, offering dual protection against leakage through the combination of body, bonnet threads, and strength-weld. The fully guided wedge design reduces wear on seating surfaces. Additionally, an optional design is available with double packing, a leak-off connection, live-loading, and a packing blowout feature, which facilitates the easy removal of old packing.
