API 6A Standard Swing Lift Type Check Valve Anti Corrosion 3 1/8" 5000psi

The API 6A swing lift type check valve provides one-way flow control and prevents reverse flow in high-pressure oil and gas applications. With a 3 1/8" bore size and 5000psi working pressure, this valve is designed for wellheads, tubing heads, casing heads, and manifolds.

The unique swing-lift design ensures rapid response to flow reversal, enhancing system safety. Constructed with anti-corrosion materials and hard-faced sealing surfaces, it delivers exceptional durability in sour gas and other harsh environments.
