The Thermostatic Mixing/Diverting Valve is designed to maintain or proportion flow based on temperature in mixing or diverting applications. In mixing applications where a controlled temperature outlet is required, the thermal mixing valve (M/D) will modulate between the hot and cold inlet feeds (ports “B” and “C”) to mix your fluid to the desired specified temperature exiting the “A” port. In diverting applications where the fluid must be directed from one section of a system to another, the thermal diverting valve (aka thermal bypass valve) will modulate inlet fluid temperature and 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.
