Subsea Check Valve


Bolted bonnet, full spin from the tilt valve, non-metallic or

metallic seal. Valve and seat sealing surface using cobalt-based

alloy Stellite surfacing, high hardness, wear resistance, high 

temperature resistance, corrosion resistance, good anti-friction 

performance and long life. The valve chamber using pressure 

self-tight sealing structure, the higher the pressure seal cavity 

the better the performance. The valve pin rotation around the 

outside of the seat, reducing violent shock occurs when closed.
