Check valves

Check valves

A check valve allows the medium to pass through in one direction, with the medium both opening the valve (when passing through the valve in the direction of flow) and closing it (when backflow or pressure drops). Check valves are commonly used as safety to prevent the medium from flowing back to critical components such as pumps.

A number of aspects are essential here. Some applications require a fast closure to immediately secure components. Other applications, on the contrary, require a slow closure to prevent water hammer.

Hanwel supplies check valves that meet these requirements and provide optimal control.
