Our 3-way Mixing and Diverting Valves (M/Ds) have internal port switching devices that automatically mix or divert fluids in proportion to temperature in any fluid system. They come standard in bronze and stainless steel housings with NPT sizes from 1/2″ to 2″. Adjustable and pre-calibrated models are available. All valves are factory tested.

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.
