Silent Type

DVD Silent Check Valves are designed to have drip tight sealing in case of back flow.

Moreover, the valve disc is soft seated, which guarantees complete closure.

Due to its spring mechanism, closure of the valve is obtained before back flow reaches the valve, thereby minimizing the surge conditions.

As a result, DVD Silent Check Valve operates in a fast way and closes silently.

DVD Silent Check Valve body is in globe design to minimize the head loss, and can be installed in any position, flow up or flow down.
