Devices to keep the oil temperature of compressors and circuits at a constant level.
TR THERMOSTATIC 3-WAY VALVES
GEA thermostatic 3-way valves are used in the oil management systems of compressors and circuits. They automatically control the temperature of the oil flow within defined tolerances based on the thermal linear deformation of the integrated thermostatic control elements. The inlets and the outlet are equipped with flanges as per DIN EN 1092-1, in pressure stages PN 25, PN 40, PN 63 and/or flanges as per ASME B16.5 150lbs, 300lbs. Welding ends and brazed ends are also available upon request. When the warm oil reaches the thermostatic control units, they expand and open a gap for the cold oil. The warm oil (e. g. from the oil separator) and the cooled oil (e. g. from the oil cooler) now start to mix and thereby maintain an almost constant oil temperature at the outlet of the thermostatic 3-way valve.
