Forged Steel Gate Valves are designed and manufactured in strict compliance with international standards such as API 602, ASME B16.34, DIN 3202, or equivalent. These valves feature a compact yet extremely sturdy design, making them ideal for high pressure and high-temperature applications. An optional Solid CoCr Alloy Wedge ensures low friction and extends the valve's service life. The packing rings are pre-compressed to 4000 psi, providing a high-integrity seal.
For welded bonnet valves, the bonnet is threaded in and torqued to a specified value, and the body-bonnet joint is strength-welded, offering double protection against leakage (body, bonnet threads, and strength-weld). The fully guided wedge reduces wear on seating surfaces, enhancing durability.
Optional designs are available, including double packing, leak-off connection, live-loading, and a packing blowout feature for easy removal of old packing.
