ThermOmegaTech®’s 3-way Mixing or Diverting (M/D) thermostatic temperature control valves are utilized in a variety of industrial applications where precision and reliability are vital to keeping production lines and processes operating efficiently. The M/D valves provide reliable control of fluid temperatures in engines, compressors, lubrication oil cooling systems, hydrostatic drive circuits, radiators, hydraulic power units, and other systems where fluids must be mixed or diverted depending on their temperatures.

These thermostatic control valves (TCVs) have internal port switching devices that automatically mix or divert fluids in proportion to temperature in any fluid system.

These valves can operate as thermal bypass valves (TBVs) to modulate fluid temperature as they divert return flow through a cooler/ heat exchanger or bypass it to a reservoir/ bypass loop when fluid temperatures are satisfied. This action assures rapid system warm-up, accurate control of fluid temperature, and reduced back pressure in the return. They can also operate as mixing valves by adjusting the flow through ports “B” and “C” to provide the desired temperature exiting the “A” port.

In mixing applications where controlled temperature outlet is required, the mixing valve’s thermal actuator will automatically proportion the flow of hot and cold fluid from two inlet ports to produce the desired outlet port temperature.

In diverting applications where fluid must be directed from one section of a system to another, the thermal actuator of the thermostatic diverter will automatically divert or switch the inlet flow to either of the two outlet ports depending on fluid temperature.

Completely self-actuating, these mixing and diverting valves require no external power source to operate simplifying installations and reducing costs. The mixing and diverting valve’s compact design and fast response time to fluctuations in a narrow temperature range make it a foundational component in any industrial application.

Available standard in bronze and stainless-steel housings with NPT sizes from 1/2″ to 2″. Customized wide temperature range, materials, and port positions available upon request. Adjustable and pre-calibrated models are also available.
