Wafer Type Rubber Coated Check Valve
Wafer Type Dual Plate Check Valve
The wafer check valve is a one-way valve with a wafer connection, and it consists of the body, disc, stem, spring and other parts. This industrial valve is mainly used in water supply and drainage systems for high-rise buildings, industrial processes and urban construction. It is particularly useful for narrow places due to being shorter than traditional check valves.
Advantages
With a specially treated coating layer on the surface, our wafer check valve exhibits superior corrosion resistance and has an extremely long service life.
The valve body adopts a two-piece design to avoid direct contact with fluids, greatly expanding its application range.
This wafer type check valve's body is manufactured from cast iron or cast steel in order to obtain excellent corrosion resistance, expanding its service life.
The valve disc is spring loaded, and has a short shutoff stroke, which reduces the risk of a hazardous water hammer.
Our wafer check valve can also be customized in appearance to satisfy individual needs.
