Description
Delta Elektrogas VMR 60 Safety Solenoid Valves is a fast opening single-stage solenoid valve, normally closed (open when energized). This type of device is suitable for air or gas blocking and releasing controls, required in gas power burners, atmospheric gas boilers, industrial kilns and other gas-consuming appliances.
Delta Elektrogas VMR 60 Function and Application
The VMR type valve is a safety shutting device using the 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 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
