Model C:

Three way thermostatic valve

Overview

AMOT Model C 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 C 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.

 1¼CCMCU12001F1AA: 11/4'' valse high flow w/3 elements (CCM), cast iron (C), connections BSP (PL) to BS 21 (U), 120°F element (120), standard element w/buna N/Nitrile-seal (01), leak hole size 1/8'' / 3,2mm (F), leak hole number (1), no customer customizations (AA)

Operation:

The valve is supplied with the temperature element assemblies 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 (3 - 6°C) 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 (4 - 6°C) above the nominal setting.
