Product Detail

Check Valve

Working Pressure: 2000~20000PSI
Material Grade: AA~FF
Temperature Grade: LU
Product Specification Level: PSL1~PSL4
Performance Requirement: PR1,PR2
Brand: Wise Channel

Check valve realize seal between valve core and body by fluid pressure, the higher the fluid pressure, the better sealing. The cavity could contain pressure in pipes all the time.

The body is made of forging allow steel, with good mechanical property, pressure endurance. Safety and reliability.

Bonnet is connected with valve body with bolts. It has seals on bonnet and inner wall of body. Fitting space between bonnet and body is designed to zero so as to minimize loading on bolts and the corrosive of bolts and   holes.

Carbide sealing surface has good anti-abrasion and corrosion resistance, the material of valve core is fabricated of anti-sulfide steel, the other parts are made with method of limiting hardness, the valve is suitable for H2S service.
