FAQ: How Do Solenoid Valves Work?

The Operation of a VMR Solenoid Valve

You use them to safely shut-off the gas in your combustion system, but how do solenoid valves work? We’ve put together a video to demonstrate. We hope you enjoy it!

The Elektrogas VMR is a fast-opening, fast-closing safety shut-off solenoid valve.
This model has proof of closure. Elektrogas proof of closure devices use a two-tone LED as a visual indicator. Green means this valve is closed.
Safety shut-off valves are normally closed. Power must be applied to open the valve.
When power is applied, the copper coil becomes an electromagnet. This model has a blue LED to indicate power is applied.
Once magnetized, the shuttle rises against the force of the inlet pressure, and the force of the spring.
The valve opens, allowing gas to flow through the system.
When power is removed, the force of the spring closes the valve in less than one second.
Valve tightness is aided by the inlet pressure. The flow of gas is stopped.
Apply power to open the valve again.

Other Elektrogas solenoid valves include the VMR..OTN, VML, and VMM
