Swing check valve API 6D carbon stainless steel

Check valve

self acting pipeline valves

VTC line check valves

Swing check valves for oil and gas and industrial pipeline applications where prevention of reverse flow is required to protect equipment and maintain system integrity. Swing check valves operate automatically and do not require external actuation, making them suitable for continuous pipeline service. These valves are commonly specified in transmission lines, pump discharge systems, and process pipelines.
