Didtek Wafer Check Valve use a swinging disc to allow or block flow. Their design allows them to be fitted in extremely tight spaces – where the flanged check valve can not be used. The wafer check valves have molded bodies around the area where the disc opens up. This is the most important difference between the above two types of valve

Wafer check valves are in-line piping valves used to control fluid flow direction and reduce or fully prevent possible back flow within plumbing systems. Wafer check valves are also known as clack valves, reflux valves, non return valves and one way valves. This valve type has been engineered to automatically eliminate the fluid flow reflux that can occur whenever a process system is shutdown. These valves feature a hinged, flap-like disk (the wafer) that is used to allow and restrict liquid flow. This disk only opens in one direction and closes shut under back pressure to seal the valve against opposing fluid flow.
Wafer check valves require a minimum amount of system fluid pressure to operate. The check opens whenever upstream pressure is greater than downstream pressure and closes whenever downstream pressure exceeds upstream.
Wafer check valve quick action and simplistic operation promotes their integration into many scenarios, markets and industries. Wafer valves are often used in water handling and intake within purification, membrane systems, desalinization, wastewater treatments and aquariums.
