Class 2500 LB Gate Valve, API 602, ASTM A105N, 4 IN, CL2500, PSB, SW

Key Specifications / Features

The Class 2500 LB gate valve from China is a forged carbon steel valve, designed for high-pressure applications. It features a pressure seal bonnet, is available in 4-inch (DN100) size with PN420 rating, and has SW ends. Certified to API 602 and ASTM A105N, it operates manually, ensuring reliable performance.

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 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 a precisely engineered torque value, and the body-bonnet joint is strength-welded, offering dual protection against leakage through the body, bonnet threads, and 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 for easy removal of old packing.
