API 6A Standard Flange Connection Swing Check Valve 2 1/16" 5000psi

Product Overview

1. The API 6A swing check valve is engineered to provide reliable backflow prevention in high-pressure oil and gas applications. With a 2 1/16" bore size and 5000psi rating, it ensures safe and efficient one-way flow control in wellheads, tubing heads, and manifolds. The sealing mechanism is energized by the fluid pressure itself, delivering improved sealing performance as pressure increases. Its integral forged body guarantees excellent mechanical strength, while hard-faced sealing surfaces and sour-resistant materials provide long-term durability and corrosion resistance.
