High-Pressure Check Valve

Detailed product information

1. The product design complies with NB/T 47044 and ASME B16.34 standards.

2. The middle cavity of the valve body is equipped with a self-sealing pressure design (Wood seal) – the higher the pressure in the body cavity, the better the seal.

3. A rotary design with low hydraulic resistance is used.

4. The sealing surfaces of the seat and valve are made by cobalt-containing hard alloy surfacing or plasma spraying, and have high thermal stability, wear resistance, and resistance to scratches.
