A 3-way mixing valve that operates with the use of an internal thermostatic element. As oil is circulated through the screw compressor, it picks up heat from the compressor. The hot oil is circulated past the thermostatic element inside the valve and it is also fed to a heat exchanger, which provides cold oil to the opposite side of the valve.
The thermostatic element modulates the flow of oil from the cold oil port and the hot oil port to maintain a temperature range ±10°F (±5.6°C) of the nominal temperature setting at the outlet.
