Automatic flange type rubber check valve slip duckbill valve

ProductInformation:

ZXF rubber duckbill check valve is made of rubber, it looks like a duckbill and is a new draining valve with functions of forward inflow and reverse back stop. Based on analysis and calculation of stress, the product is made via special process with different design principles, different rubber prescription under different operating conditions. During the forward operation, water flows in from the inlet, and the lower water pressure will open the valve, the higher the water pressure is, the wider the valve is opened, and the higher the water flow is. During the back stop operation, the valve will close naturally, seal and stop. The higher the water pressure is, the tighter the valve is, the better the sealing effect. The product is widely used in draining water of municipal construction, water conservancy and sewage process so as to prevent reverse flow and reflux, it is an ideal product to replace flat valves.
