Product Details:

Single Disc Check valves are defined as the mechanical device which allows the flow of fluid to go in only one direction. Single Disc Check valves work by the differential pressure and fluid flow opening the hinged discs and compressing the spring. When the flow begins to slow down the spring gradually assists in the closing of the valve. The spring loading effectively prevents the slamming (also known as water hammer) associated with other check valves.
