The VMR type valve is a fast opening solenoid valve that is normally closed.
When the coil is not energized the spring works on the disc keeping the gas passage closed. When the coil is powered the valve opens. When power is switched 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 kilns and in all gas equipments which use gas solenoid valves (qualified for continuous service – 100% ED). Suitable for high-frequency switching systems.
