VMR VMR60
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).
Functioning and application
The VMR type valve is a safety shutting device using auxiliary power supply.
When it is de-energized, the spring pushes on the seal disc, keeping the gas passage closed.
Now, the inlet chamber is under the gas line pressure which forces on the disc, increasing the
closing function and improving the seal.
When it is de-energized, the spring pushes on the seal disc, keeping the gas passage closed.
Now, the inlet chamber is under the gas line pressure which forces on the disc, increasing the
closing function and improving the seal.
When the coil is powered the valve opens rapidly, against the strength of the spring and gas
pressure. The flow may be adjusted using the regulating screw on the top (see the installation
and service instructions).
If the power supply is shut off, the valve rapidly closes, interrupting the gas flow.
pressure. The flow may be adjusted using the regulating screw on the top (see the installation

If the power supply is shut off, the valve rapidly closes, interrupting the gas flow.
