Bolted Bonnet Gate Valve, API 602, A105N, 1 Inch, CL300, RF

Key Specifications / Features

The China Bolted Bonnet Gate Valve Supplier offers high-quality gate valves designed in accordance with API 602 and ASTM A105N standards. These valves feature a carbon steel body, ensuring durability and reliability. They are available in a standard size of 1 inch (DN25) and are rated for Pressure Class 300 LB and PN50, making them suitable for a wide range of industrial applications. The valves come with raised face (RF) flanged ends for secure and leak-free connections.

Forged Steel Gate Valves are engineered 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 robust design, ideal for high-pressure and high-temperature applications. An optional solid CoCr alloy wedge ensures low friction and extended service life. Packing rings are precompressed to 4000 psi, providing a reliable and high-integrity seal. For welded bonnet types, the bonnet is threaded and torqued to a precise value, then strength-welded to the body, delivering double protection against leakage through the threads and weld joint. A fully guided wedge minimizes wear on seating surfaces. Optional features include double packing, leak-off connections, live-loading, and a packing blowout mechanism for easy removal of old packing.
