ThermOmegaTech’s 3-way Mixing and Diverting Valves (M/D) 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 or heat exchanger, or bypass it to a reservoir or 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, the M/D’s will proportion the flow from two inlet ports to produce the desired outlet port temperature.

In diverting applications, the M/D’s will divert or switch the inlet flow to either of the two outlet ports depending on fluid temperature.

Completely self-actuating, these valves require no external power source to operate simplifying installations and reducing costs. Available standard in bronze and stainless steel housings with NPT sizes from 1/2″ to 2″. Customized temperature, materials, and port positions available upon request. Adjustable and pre-calibrated models are also available.
