Heater Magnet Valve and Shut-Off Valve

The Heater Magnet Valve is an electrical valve that opens and closes when the furnace needs heat. It is a safety feature. It requires a thermopile (an electrical device that measures temperature) to operate. It works with a 12 volt power source. The valve is normally closed but can be opened by turning the valve handle.

This safety feature protects the home from dangerous situations. It works by generating thermoelectric power when it is heated. The temperature difference between the two sides of the magnet valve and the gas creates a closed-loop current. When the gas is not heated properly, the magnet valve will lose its suction and the gas path will close. This valve is also used as a safety precaution to prevent fire.

The Shut-off Valve comes in dry battery and thermocouple versions. It is designed with a simple, compact design. It also features a safety shut-off function that prevents gas from flowing out when there is a problem with the appliance. This valve is commonly used in boilers and water heaters.
