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

The Firomatic HW-165 Wheel Fusible Valves & Thermal Switches Silver 12510BU is a fusible thermal safety part that controls fuel flow while providing automatic shutoff during excessive temperature conditions. Its fusible element responds to elevated heat by releasing the internal valve mechanism, interrupting the connected fuel passage when the specified thermal condition occurs in HVAC systems. A wheel-type actuator permits manual opening and closing during operation, while the thermal operation provides an additional automatic response to abnormal heat. The silver-finished body integrates into compatible fuel-line assemblies through its designated connections. Heat-activated closure adds an essential layer of protection to fuel-handling applications.
