Description
The VMR352 is an auto-reset, fast-opening single-stage gas solenoid valve, suitable for air or gas blocking and releasing control, commonly applied in gas power burners, atmospheric gas boilers, furnaces, and other gas-consuming equipment. It is fully computer-tested, ensuring reliability, leak-tight operation, and compliance with EN161 Class A Group 2 and SIL3 IEC EN 61508 standards. All components are engineered to withstand harsh mechanical, chemical, and thermal conditions with enhanced corrosion and sealing performance.

Spare Coils
→ 230 V AC High Power – VMR1930.1415 (for VMR352 + VMR62, 6 Bar version)
→ 230 V AC – VMR1930.1416 (for VMR352, VMR42 + VMR62)
→ 24 V AC/DC – VMR1930.1452 (for VMR352, VMR42 + VMR62)

Applications: Industrial gas burners, heating systems, furnaces, and controlled air/gas systems requiring fast, reliable shut-off and precise flow control.
