A universal thermocouple ensures reliable flame detection in water heaters. It generates a small voltage when heated, keeping the gas valve open. If the flame goes out, the thermocouple cools and shuts off the gas, preventing leaks and ensuring safety.
The pin length affects response time and positioning. Long pins reach deeper into the flame for faster detection, while short pins offer stability in compact systems. Both types are designed for precise thermal feedback in flame failure systems.
These valves offer improved sealing, faster response, and higher durability. They enhance safety by ensuring immediate gas cutoff during flame failure and improve efficiency with minimal power consumption.
