Industrial 66040-080 Three-Way Thermostatic Valve

Description:

The Thermal Transfer 66040-080 Iron Thermostatic Valve is a three-way thermostatic control valve designed to automatically regulate fluid temperature by diverting flow between a heat exchanger and bypass circuit. Commonly installed in hydraulic systems, lubrication systems, engine cooling circuits, and industrial process equipment using 1-1/2 in. NPT connections. Maintenance teams, OEMs, and industrial technicians use this thermostatic valve for equipment replacement, preventive maintenance, and maintaining consistent operating temperatures.

Applications:

The Thermal Transfer 66040-080 Iron Thermostatic Valve automatically controls fluid temperature without external power by directing flow through or around a heat exchanger. It is commonly used in hydraulic power units, diesel engines, compressors, lubrication systems, and industrial cooling applications.
