Product Description

CHECK VALVE

 

1.This product design and manufacturing completely meet the requirement of API Spec 6A Wellhead assembly and X'mas tree specification,often used for kill manifold.

2. The body is forged alloy steel.

3.Bonnet and body are connected by stud,seals are for bonnet and insider of wall body,which shall ensure sealing performance reliable.

4. Valve core and body sealing surface are welded by hard alloy,which can be used in the environment containing H2S..

 

Check Valves are important part of wellhead equipment and widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety.

 

Flapper Check Valves - Clapper check valves are designed for well service applications such as fracturing, cementing and acidizing. The flapper check valve is placed in the treating line to allow flow to the well but isolates and back flow to go upstream in the valve. This provides a safety device at various locations in the flow line and assure that pressure and fluid can not backup into the manifold or into pumps.
