3/4" BSP Gas Solenoid Valve EN161 Normally Closed Elektrogas VMR22
The Elektrogas VMR22 is a high-capacity EN161 Class A certified gas safety solenoid valve designed for rapid shut-off and reliable control of natural gas, LPG, air and specialist fuel gases. Featuring a normally closed fail-safe design, the valve opens when energised and automatically closes within one second when power is removed, providing dependable protection for industrial gas installations and burner systems.
Manufactured from corrosion-resistant aluminium with EN549 certified NBR gas seals, the VMR22 is designed for continuous duty operation and is widely used on industrial burners, atmospheric boilers, furnaces, kilns, gas trains and process heating equipment. The integrated flow adjustment enables precise gas flow control, whilst the built-in 600-micron filter protects both the valve and downstream equipment from contamination.
