Custom Forged Gate Valve, API 602, ASTM A105N, Bolted Bonnet

Key Specifications / Features

The China Custom Forged Gate Valve Supplier offers a range of Forged Steel Gate Valves that are designed to meet API 602 standards and are made from ASTM A105N forged steel. These valves feature a bolted bonnet design, ensuring durability and reliability in high-pressure applications. They are available in customized sizes and pressure ratings, with RF (Raised Face) flanged ends for secure connections. The valves are suitable for a variety of industrial applications, including those involving water, gas, oil, and other media.

Forged Steel Gate Valves are meticulously designed and manufactured in strict accordance with international standards such as API 602, ASME B16.34, DIN 3202, or equivalent. These valves feature a compact yet extremely robust design, making them ideal 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 highly reliable 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 (body, bonnet threads, and strength-weld). The fully guided wedge reduces wear on seating surfaces. Optional designs are available with double packing, leak-off connection, live-loading, and a packing blowout feature for easy removal of old packing.
