Figure 5-2 – OIL MIXING VALVE (THERMOSTATIC) HARDWARE

The valve mixes cooled and hot oil, prior to delivery to the oil filter and oil injection line, to maintain a system
discharge temperature of 203º F. At startup, the mixing valve is on full bypass mode. As system heat load
increases with ambient temperature or load, the mixing valve sends more oil flow to the cooler to maintain
adequate compressor discharge temperature.

See Figure 5-3, for pressure dew point trends at various combinations of operating pressures and saturated
ambient air temperatures.
