Bellows Seal Gate Valves are designed and manufactured to meet international standards such as API 602, ASME B16.34, and DIN 3202, ensuring reliable performance in high-pressure and high-temperature applications. These valves feature a compact yet robust design, with an optional solid CoCr alloy wedge that provides low friction and extended service life. The packing rings are precompressed to 4000 psi, ensuring a high-integrity seal. For welded bonnet valves, the bonnet is threaded and torqued to an engineered torque value, while the body-bonnet joint is strength-welded, offering double protection against leakage. The fully guided wedge reduces wear on seating surfaces, enhancing durability. Optional features include double packing, leak-off connections, live-loading, and packing blowout for easy removal of old packing.
