Parameter

○ Nominal diameter: 3/8" NPT (1/8"-1")

○ Working pressure: 6000 psig (413bar), with a maximum of 10000 PSI (689bar)

○ Operating temperature: -10°F to 625°F (-23°C to 320°C)

○ Actuation pressure: 1psig to 25 psig (0.02 to 1.7 bar)

○ Product material: 304, 316L, and other special materials

○ A variety of port types and valve body materials are available for selection

Performance

○ Materials suitable for sour gas environments meeting NACE MR0175/ISO 15156 standards are available for selection

○ Hard-sealed elastic buffer valve seat, noiseless, and effective check function

The one-way valve adopts a needle seal type, with the O-ring only serving as an auxiliary seal for grinding, effectively solving the problem of aging sealing components of the valve and extending the service life of the valve

○ Each valve undergoes a sealing test before leaving the factory, which includes a 5% test at 1.5 times the rated working pressure, a 1PSI sealing test, and an opening test

Application

The stainless steel internal thread high-pressure check valve is precisely manufactured using 316 or 304 stainless steel, featuring corrosion resistance, high temperature tolerance, and strong pressure-bearing capacity. It is suitable for high-pressure clean or corrosive medium pipelines. The internal thread connection method allows for convenient installation, reliable sealing, compact structure, and sensitive opening and closing, effectively preventing medium backflow. It is widely used in hydraulic systems, chemical equipment, instrumentation, and high-pressure gas/liquid control systems, ensuring safe and stable operation without leakage.
