Single acting normally closed Valves N.C.

Rovel gate valves by Officine Meccaniche Parenti belonging to this series are called Normally Closed (N.C) to indicate the type of command in rest position. By actioning them, it is possible to switch the valve causing the opening and therefore the exit of the fluid.

In order to work correctly, they require a pressure minimum differential (opening and closing without electric feeding). They offer excellent performances also in presence of low working  pressure.
