Check valve effects seal between valve core and body by fluid pressure. The higher the fluid pressure,the better seal effected. The cavity could contain pressure in pipes all the time.
Material Class: AA~FF
Nominal Bore: 2 1/16”～7 1/16”
Temperature class: K ~ U
Working Pressure: 2000~15000psi
Product Specification Level: PSL1~PSL4
Performance Requirement: PR1,PR2
Main features:
The body is made of forging alloy 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 is made with method of limiting hardness,the valve is suitable for H2S service.
