API 6A Wellhead Flow Line Check Valve 3" x 6000 psi

Wellhead Check Valve Flange End API 6A

 

Overview of the Flow Line Check Valve

 

The flow line check valve is a kind of  non-return valve. With the metal-to-metal seal by the pressure

grows, the flow line check valve has better the sealing function. The valve chamber can bear the

pressure of the pipeline anytime and prevent liquid backstreaming by self-closing baffle. The flow line

check valve is made of alloy steel and manufactured in full conformance with API-6A Standard, the

check valve is composed by valve body, valve deck, valve seat and valve rod.
