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.
