Features

The valve flap of the lift check valve is disc-shaped and rotates around the shaft of the valve seat passage. Because the valve passage is streamlined, the flow resistance is smaller than that of the butterfly check valve, which is suitable for low flow rate and Large-caliber occasions where the flow does not change frequently, but it is not suitable for pulsating flow, and its sealing performance is not as good as that of lifting. The butterfly check valve is divided into three types: single-valve, double-valve and multi-half. These three forms are mainly divided according to the valve diameter. The purpose is to prevent the hydraulic shock from being weakened when the medium stops flowing or reverses.
