Atlas Copco 1619733000 is the thermostatic valve element (core) with its return spring, which controls how much oil goes through the oil cooler. It is used on Atlas Copco rotary screw air compressors. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Compressor running hot
An element stuck in bypass sends hot oil straight back to the airend and the compressor trips on high temperature.
Water in the oil
An element stuck open overcools the oil, so condensate does not boil off and the oil turns milky.
Scheduled service
Atlas Copco service plans change the thermostatic element at the major services. Fit a new spring and O-rings at the same time.
Fitting tips
Vent the compressor and drain the oil below the valve housing, note the orientation of the old element, and clean the housing bore before fitting.
