Manualy reset solenoid valve MSV

MSV solenoid valves from Guiliani Anello are designed to isolate supply of gas to monitored facilities. They are available in two manufacturing options that differ with the operation pressure of gas lines: MSV 0.5b up to 50 kPa and MSV 6b up to 0.6 MPa and can operate with two control voltages for valve solenoids: 12 VDC or 230 V AC. The MSV valves can be installed in areas with the class of hazards from 2 to 22.
In the mode of regular operation the valve is open and enables unobstructed flow of gas. Tight shutoff of the valve resulting in isolation of gas flow is carried out against an electric signal, provided for instance by the Control Unit of the Gas Safety System. The valve can be reopened only manually after making sure that the reason for the valve triggering is eliminated.
Device structure: aluminium body and lid, actuating spring made of alloy steel, adjusting steel piston, rubber (NBR) membrane and sealing ring, other parts made of brass, aluminium or steel with galvanized coating. These shutoff valves are installed between the main valve at the gas line branch and the building entrance.
