Product Description Usage: Apply a gas water heater, combustion heater, BBQ gas appliance, dryer apparatus for control components. How it works: Thermocouple and solenoid valve for supporting the use of the composition of gas with flame failure safety device, the thermocouple is to provide micro-power sensor, solenoid valve to control the device with the Department of thermocouple tip heated by the flame When the cold end and hot end temperature difference between the thermoelectric power due, thus creating a closed loop current, so that solenoid valve in the external and common role of magnetic fields, is pull the state, gas flow, when the flame goes out, the thermocouple rapid loss of potential, loss of suction valve being reset under the action of compression spring to close the gas line, which play a security role. Scope: Natural gas, liquefied petroleum gas, artificial gas.
