The Forum/ PBV check valves are designed for reliability in high velocity service applications to prevent backflow. These check valves are designed to operate in either vertical upflow or horizontal pipe runs. Seating surfaces are hardfaced with Stellite®6 to provide high life cycle capability. The swing check design offers a higher flow coefficient than a tilting disc design with higher flow area. The tilting disc is a non-slam design.
