Api 598 Stainless Steel Wafer Type Single Plate Swing Check Valve
the disc of the swing check valve is disc shaped and rotates around the rotating shaft of the seat passage. because the inner channel is streamlined and the flow resistance is smaller than that of the lifting check valve, it is suitable for large caliber situations with low velocity and irregular flow, but not suitable for pulsating flow, and its sealing performance is not as good as that of lifting type. The rotary check valve is divided into three types: single valve type, double valve type and multi half type. These three forms are mainly divided according to the valve caliber, in order to prevent the medium from stopping flow or backflow, and to reduce the hydraulic impact.
Metal seal or rubber seal.
