Normally closed (NC) – Valve opens only when energised
Sizes available: DN50 to DN150 and 1/4 to 2 BSP or NPT
Voltage options: 12vDC or 24V, 110V, 230V AC/DC
Manual flow control reset, extra pressure test ports and closed position micro switch options available on select models
Max working pressure: 200m bar up to 6 bar (depending on model)
Approvals: EN161, CE, optional ATEX for hazardous zones
Ideal Applications for VMR Valves
Industrial gas burners and combustion systems
Heating plants and commercial boiler rooms
Gas emergency shut-off and safety interlocks
Process gas control systems
Gas valve trains and control manifolds
The fast-closing mechanism is critical in preventing gas leaks, backflows, or flame failures, ensuring maximum safety in demanding environments.

Product Overview
The Elektrogas VMR series is a cutting-edge, auto-reset fast-opening failsafe closed gas safety valve.
This valve operates on a power-to-open/power-off mechanism that automatically closes the valve in the event of a power failure, enhancing safety by preventing gas leaks.
Certified to EN161 Class A standards, the VMR valve is suitable for use with air, natural gas, and other non-aggressive gases, as well as more challenging gases like propane, coke oven gas (COG), and biogas.
The VMR series is designed to meet the highest safety standards, with special versions available featuring epoxy coatings for added protection against aggressive gases, including coke oven gas and biogas containing hydrogen sulphide traces.
The VMR gas solenoid valves are ideal for a wide range of applications, including gas-powered burners, gas boilers, industrial kilns, and other critical gas appliances where stringent safety protocols are paramount.

Key Features and Specifications
Pressure Range:
Suitable for gas systems operating at pressures from 0 to 200 millibars, with options for 360 millibar and 6 bar pressure settings to accommodate varying system requirements.
Media Compatibility:
Designed for use with air and natural gas, the VMR valve also offers options for biogas (Option J) and coke oven gas (COG) (Option K), making it versatile for different industrial environments.
Certifications:
The VMR valve is EN161 Class A Group 2 certified, with CE registration 0063AQ1350 by GASTEC and SIL3 certification per IEC EN 61508 Intercert certificate no. C-IT.AB86.B.04357, ensuring compliance with global safety standards for gas control systems.
Seals:
The valve features NBR-based rubber seals, certified to EN549 for gas applications, ensuring a secure and durable seal under varying pressure conditions.
Open/Close Time:
Ultra-fast opening and closing response, with an open/close time of less than 1 second, ensuring prompt action in critical gas safety situations.
Coil Specifications:
The VMR valve is equipped with a 100% duty-rated coil, offering long-lasting reliability and performance. The coil is housed in an IP54-rated terminal box with M20x1.5 threads (EN50262) and a PG9 cable gland. Options for an IP65-rated coil and a low-power coil (L) are available for energy efficiency. The valve can be supplied ATEX Ex-proof, suitable for Zones 2 and 22 per the 94/9/EC Directive, ensuring safe operation in explosive environments (Category II 3 G, D protection Ex n A II T4 X, Ex tD A 22 IP54 T135).
