A check valve utilizing a linear design Silent Check Valve places the disc in-line with the seat. Ball-type check valves have the least expensive form of construction but as the ball is not guided there is a tendency for leakage to occur.
Threaded ends from 1 to 3 DN 25 to DN 80.
In dynamic conditions flow The water pressure exceeds the spring tension. Fluid flowing to the right will push the ball bearing against the spring and open the valve to permit flow.

Ball Check Valves are simple and compact and commonly used on small water or wastewater pumps where economy is important. A Ball Check Valve consists of a threaded or flanged body with internal features that guide a rubbercoated ball in and out of the seat as the flow goes forward and reverse. Although manufacturers claim their check valves are leak-free in one direction of flow and allow free flow in the reverse direction a tiny scratch wear mark or imperfection on the poppet or scat will permit some leakage.
