ROVEL shutter valves by Officine Meccaniche Parenti srl are mechanic components used to intercept, not regulate, fluids. This series is available in the versions normally closed N.C. or normally open N.O., with valve body in different materials and different pressures and flow rates.
Some models come with a knob for a possible manual acting, signaling also an "open or close" status. Other models instead have an opening that signals the "Open or Closed" status. The installation is advised where a minimum dripping is accepted. The body valve houses the mechanisms for the fluid obstruction. It is allowed the usage also as solenoid. In order to work correctly they require a minimum pressure differential (opening and closing without electric feeding). Excellent performances also in presence of low working pressure.
Technical characteristics common to all the valves models of this series
Safety hole: it signals the damaging over time of the sealing gaskets that separate the actuator from the intercepted fluid.
