ASTM A105N Gate Valves, API 602, 1/2 Inch, 2500 LB, SW Ends

Key Specifications / Features

The China ASTM A105N Gate Valves Supplier offers high-quality gate valves designed to meet API 602 standards. These valves feature a forged carbon steel body, ensuring strength and durability. With a 1/2 inch size (DN15), they are rated at Class 2500 LB and PN420, making them suitable for high-pressure applications. The valves are manually operated and come with socket welded ends for secure and efficient installation.

Forged Steel Gate Valves are engineered and produced in strict adherence to international standards such as API 602, ASME B16.34, DIN 3202, or equivalent. These valves feature a compact yet extremely robust design, making them suitable 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.
