Products Detail

The disc of the piston type check valve is in disc shape and rotates around the shaft of the valve seat passageway. Because the inner passage of the valve is streamlined and the flow resistance is smaller than that of the rising butterfly check valve, it is suitable for large diameter occasions with low flow rate and inconstant flow, but not suitable for pulsating flow. Its sealing performance is not as good as that of the lifting type. Butterfly check valve is divided into single valve, double valve and half of three types, the three forms are mainly divided according to the valve diameter, the purpose is to prevent medium stop flow or reverse flow, reduce hydraulic impact.
