Safety solenoid valves for air and gas, fast opening and fast closing type
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.
Features
The valves are made of aluminum alloy die-cast (or hot-pressed brass for OTN versions), with a wide range for inlet/outlet connections from DN 8 (1/4”) up to DN 150 (6”).
Sealings are made of NBR-based rubber certified for use with gas (EN 549).
Suitable for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN 437).
Special versions suitable for aggressive gases, free of non-ferrous metals and with FPM seals.
Pipe connections meet Group 2 and backpressure sealing is compliant with Class A, according to EN161 requirements.
The whole range can be provided in Ex-proof execution, for use in Zones 2 and 22, according to 2014/34/EU Directive (ATEX).
The valve is open only when energized: if, for any reason, power supply goes down, the valve closes immediately (intrinsic safe).
