API 6D Swing Check

Forum’s PBV® swing check valves are a trusted choice for oil and gas operations around the world, encouraging full, unobstructed flow at regular pressures. Under low-pressure conditions, the valve provides tight closure that offers a cost-effective, low-maintenance solution to prevent backflow. Our swing check valves are fully manufactured and tested to American Petroleum Institute (API) 6D and American National Standards Institute (ANSI) B16.34 specifications.
