Delta Elektrogas- VML Safety Solenoid Valve For gas | Safety Solenoid Valves
The VML type valve is a safety valve that is normally closed, with a fast or slow opening and an adjustable rapid section for initial gas flow. When not in the working position the spring works on the disc keeping the gas passage closed.
When the coil is powered the valve opens rapidly in the first section of the flow, then slowly, with adjust-able speed. 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 equipment which uses gas solenoid valves (qualified for continuous service – 100% ED).
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
