Pressure Seal Check ValvePressure Seal check valves are designed for reliability in high velocity service applications to prevent backflow. The check valves are designed to operate in either vertical or horizontal pipe runs. Seating surfaces are hardfaced with Stellite 6 to provide high cycle capability. The swing check design offers better flow characteristics than a tilting disc design with higher flow area. The tilting disc is a non-slam design which minimizes the potential for water hammer. Pressure Seal tilting check valves feature a fitted disc that’s guided to ensure an effective tight seal and to minimize vibration.
