43-3 - 3-way general process temperature regulator

The Type 43-3 self-operated temperature regulator is designed to work in all general industrial applications. This temperature regulator is an unbalanced three-way valve design with flanged, threaded, and welding end connections.

Temperature regulator with mixing or diverting valve designed for plants heating or cooling with liquids, consisting of an unbalanced three-way valve with a control thermostat containing a set point adjustment ring, a capillary tube, and a temperature sensor which functions according to the adsorption principle.

In mixing service when the temperature rises, port A opens and port B closes. In diverting service when the temperature rises, port A closes and port B opens.
