Firomatic HW-165 Wheel For Fusible Valves & Thermal Switches Silver 12510bu

The Firomatic HW-165 Wheel Fusible Valve & Thermal Switch is a temperature-responsive control component used in compatible fuel-fired heating equipment. It interacts with connected control and fuel system assemblies when elevated temperature conditions occur within the equipment. Commonly applied in oil heating applications, it is positioned within the safety control section of HVAC systems where temperature-sensitive operation is required. It identifies this specific configuration for use with compatible equipment. Integrated with associated control assemblies, it contributes to coordinated system response during normal operating and temperature-monitoring conditions.
