Swing check valve

Swing check valve

The disc of the swing check valve is disc-shaped and rotates around the rotating shaft of the seat channel. Because the channel in the valve is streamlined and the flow resistance is smaller than that of the lift check valve, it is suitable for large diameter occasions with low flow rate and constant flow change, but it is not suitable for pulsating flow and its sealing performance is inferior to that of the lift check valve. The swing check valve is divided into three types: single valve type, double valve type and multi valve type. These three types are mainly divided according to the diameter of the valve. The purpose is to prevent the hydraulic impact from weakening when the medium stops flowing or reverses.
