Model H:

Three way thermostatic valve

AMOT Model H Thermostatic Valves are fully automatic, 3-way fluid temperature controllers for diverting or mixing applications. They are used to provide reliable control of fluid temperatures in engine water jacket and lubricating oil cooling systems. These valves are suitable for process control and industrial applications where fluids must be mixed or diverted, depending on their temperatures. They may also be applied to cogeneration systems to control temperatures in the heat recovery loop assuring proper engine cooling and maximizing heat recovery. 


Features and Benefits:

  • Positive 3-Way Valve Action

  • Completely Self-Contained

Temperature ranges: 13-116°C  (55-240°F)

Connections: Flanged

Material: Steel


The valve is supplied with the temperature element assembly factory-set to the nominal temperature setting. Temperature is sensed at Port A, which remains open to Port B (bypass) until the fluid temperature reaches a point 5-10°F below the nominal setting. As the temperature continues to rise, the sliding valve moves to close off Port B and open Port C (connected to the cooler or heat exchanger.) Port B is fully closed 8-10°F above the nominal setting. The valve continually modulates the fluid flow to maintain the nominal temperature. For optimum control, the system should be sized so that approximately one half the total fluid flow passes through the cooler at full load.
