Rovel gate valves by Officine Meccaniche Parenti that belong to this series are defined double acting to indicate the type of command which, in absence of pressure, stays in the position in which it is. By the actioning, it is possible to switch the valve causing the closing or opening of the fluid flow.
In order to work correctly, it is necessary a minimum pressure differential (opening and closing without electric feeding). Excellent performances also in presence of low working pressures.
