Water Heater Gas Valves

Water heater gas valves are essential components for controlling the gas supply to the pilot light in water heating systems. These valves ensure smooth ignition and steady gas flow, enabling the pilot light to heat the thermocouple and maintain consistent water temperatures. Our range of water heater gas valves is specifically designed for standing pilot applications, making them both easy to install and replace. With advanced features like the Resettable Emergency Temperature Cutoff, these valves help reduce the risk of scalding, lower labor costs, and minimize repair time, ensuring safe and efficient operation for both residential and commercial water heaters.
