DVD Foot Valves are used to prevent back flow of the medium from the suction pipe of pumps; when the pump is turned off.
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 Foot Valve operates in a fast way and closes silently.
Moreover, with the filter function, it prevents residuals from entering the pipeline and harming the pump or other crucial devices.
DVD Foot Valve body is in globe design to minimize the head loss, and can be installed in vertical position with the direction of flow upwards.
