AWP Thermostatic 3 way valves

Devices to keep the oil temperature of compressors and circuits at a constant level.

AWP 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 outlets are fitted with flanges as per DIN EN 1092-1, in the compression phases PN 25, PN 40, PN 63 and/or flange to ASME B16.5 150lbs, 300lbs. Welding end and solder end types are also available upon request. When the warm oil reaches the thermostatic control units, the latter expand and reveal a gap opening for the cold oil. Thus the warm oil (e.g. from the oil separator) and the cooled oil (e.g. from the oil cooler) start to mix. This keeps the oil temperature at the outlet of the thermostatic 3-way valve more or less constant.
