Chicago Pneumatic C106 Thermal Valve Kit - 2200599825
A compressor thermal valve opens when the oil gets hot to let coolant/oil flow through the cooler before the oil is sent back into the sump tank. This prevents the compressor from overheating. If your compressor is consistently shutting down on high temp and your oil is full, more than likely this valve needs to be replaced.
It is recommended to replace the thermal valve every two years or 8,000 hours of operation. This valve was used on a variety of Chicago Pneumatic air compressors, including the QRS10, QRS15, QRS25 and QRS30 rotary screws.
This 2200599825 thermal valve part number is also commonly shown as 2200 5998 25 and 2200 5998 25. The description may also read Thermostatic Valve Kit. This is an OEM part that was also used on several Atlas Copco and Quincy air compressors.
