The gas detector is the device that detects the presence of explosive and toxic gases in the area and timely provides the appropriate danger signal through sound means, while simultaneously activating the gas electromagnetic valve, which interrupts the gas supply in the areas where the leak has been detected.

Specifically, the gas detector contains a sensor specially designed to detect propane and butane (which make up the gas).

The gas electromagnetic valve is a device responsible for interrupting the gas supply when a leak of explosive and toxic gases is detected in the area, through the gas detector.
