Application
The valve flap of the lift check valve is disc-shaped and rotates around the shaft of the valve seat passage. The flow passage is streamlined and the flow resistance is smaller than that of the butterfly check valve. It is suitable for low flow rate and flow. Frequently changing large diameter applications, but not suitable for pulsating flow, the sealing performance is not as good as 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.
