Model E:

Three way thermostatic valve

AMOT model E thermostatic valves are available in a wide selection of sizes and settings to fill a multitude of fluid temperature control requirements. These valves may be mounted in any position and use the proven expanding wax principle to actuate the 3-way temperature element assemblies. The model E valves may be used for diverting or mixing service. They make very economical temperature limiting valves to prevent scalding in home, motel or hotel hot water supply systems. Radiant heating systems can use these valves in limiting water temperature to prevent surface cracking and over-heating of plastic piping. Other applications include electronic and battery cooling circuits, pump temperature relief valves etc.

Features and Benefits:

  • No external power source required – simple, low cost installation

  • No user setting needed – "fit and forget solution"

  • Small number of parts – simple maintenance and low cost of ownership

  • Robust design capable of high vibration and shock applications

  • Easy installation, operates in any mounting position

  • Automatic self-sensing control with positive proportional valve action


  • Engine compressors and cooling systems

  • Process control

  • Cogeneration heat recovery loops

  • Lube oil systems

  • Heat recovery

  • Lubricating oil temperature control

  • Temperature mixing and diverting

Temperature ranges:  29°C-114°C  (85°-237°F)


Materials:  House in bronze, cast iron, carbon steel or stainless steel

Tilkoblinger: Flanged or threaded


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 8-10°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 about 1/2 the total fluid flow is passing through the cooler at full load.
