Riello Solenoid Valve 3020437 R40 Mectron

The solenoid valve is typically used in the fuel supply line to regulate the flow of fuel to the burner's combustion chamber. When the burner is in operation, the solenoid valve receives an electrical signal to open, allowing fuel to flow to the burner. When the burner is turned off or there is a safety shutdown, the solenoid valve receives a signal to close, cutting off the fuel supply and shutting down the burner.
