Bolted Bonnet Gate Valves, API 602, ASTM A105N, 1 IN, CL300

Our Bolted Bonnet Gate Valves Manufacturer produces high-performance forged gate valves in compliance with API 602 standards. These valves are made from carbon steel ASTM A105N, ensuring durability and strength. With a 1-inch diameter (DN25) and a pressure rating of Class 300 LB (PN50), they are designed for reliable performance in demanding applications. The valves feature RF flanged ends for secure and easy installation, and they are manually operated for precise control.

Forged Steel 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 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 a precisely engineered torque value, with the body-bonnet joint further secured by strength welding. This dual protection mechanism (body, bonnet threads, and strength weld) effectively guards against leakage. The fully guided wedge design minimizes wear on seating surfaces. Additionally, optional features include double packing, leak-off connection, live-loading, and a packing blowout mechanism for easy removal of old packing.
