Definition of Ferrule High-Pressure Check Valve

The ferrule high-pressure check valve is specifically designed for high-pressure fluid systems that require reliable non-return performance and secure connections without welding. Its core feature lies in the ferrule-type connection structure. Through the ferrule (compression sleeve), a tight seal is formed between the valve and the pipeline, which offers the advantages of quick assembly/disassembly and reusability.

Technical Parameters of Ferrule High-Pressure Check Valve

Application Fields of Ferrule High-Pressure Check Valve

Oil industry, petrochemical industry, semiconductor industry, pharmaceutical industry, natural gas industry, chemical industry, metallurgy industry, power industry, nuclear power industry, light industry, environmental protection industry, scientific research field, food industry, shipbuilding industry

Structural Features of Ferrule High-Pressure Check Valve

Materials suitable for sour gas environments meeting NACE MR0175/ISO 15156 are available (note: "MRO175" corrected to industry-standard "MR0175")

Hard-sealed elastic buffer valve seat, no noise, and effective non-return function

The check valve adopts a needle-type sealing design; the O-ring only serves as an auxiliary grinding seal, which effectively solves the problem of valve seal aging and extends the service life of the valve

Each valve undergoes a 22 MPa gas strength test, a 1 PSI seal test, and a cracking test before leaving the factory
