Class 1500 LB Gate Valve, API 602, A105N, 1 Inch, PSB, RTJ

Key Specifications / Features

The China Class 1500 LB Gate Valve Manufacturer produces high-quality Pressure Seal Bonnet Gate Valves designed to meet API 602 standards. These valves feature a forged carbon steel body made from ASTM A105N material, ensuring durability and reliability. With a 1-inch size (DN25), they are rated at Class 1500 LB and PN250, making them suitable for high-pressure applications. The valves come with a ring-type joint (RTJ) flange and are operated manually using a handwheel.

Pressure Seal Gate Valves are meticulously 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 robust construction, 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 (through body and bonnet threads as well as the strength-weld). The fully guided wedge reduces wear on seating surfaces. Optional designs are available with double packing, leak-off connections, live-loading, and a packing blowout feature, facilitating the easy removal of old packing.
