The VMR type valve is a fast opening solenoid valve that is normally closed. When not energized the spring works on the seat keeping the gas passage closed. When the coil is powered the valve opens. When power is cut off the valve rapidly shuts.This type of device is suitable for gas and air blocking and adjusting controls in atmospheric burners or fan-assisted burners, in industrial ovens and in all gas equipments which use gas solenoid valves (qualified for continuous service - 100ED).
