Check & Stop Check Valves Check Valves

Check and Check Stop Valves are automatically activated locking units opened by the pressure exerted by the working medium upon the valve plate.

Check valves stop check valves are automatically activated locking units. They are opened by the pressure exerted by the working medium upon the valve plate. As soon as the flow is interrupted or the flow direction is reversed, the valve locks automatically.The built-in damping device makes this type of valve especially suitable in cases where the power requirement varies significantly. installed on the pressure or suction side of compressors, or in pipes in which only one direction of flow is permitted. GEA check valves are maintenance-free. Any defects that occur in the functional performance of the valves can be repaired.
