How does a fireplace gas valve work?
Thermocouples are passive sensors that generate an electrical current when the junction in an open circuit is exposed to a thermal gradient. The heat from the pilot flame is sensed by the thermocouple and the induced electrical charge actuates an electromagnet inside the gas valve that allows flow to the main burners.
What is a zero governor gas valve?
Zero Governor Regulator: Controls the outlet pressure of the valve with the goal of zero pressure at the outlet allowing the flow of gas to only occur with a negative pressure signal from the venture mixer. Throttle: An adjustment that defines the maximum gas flow through the gas valve at high fire.
