Atlas Copco 2200599825 Thermostatic Valve Kit C106

The 2200599825 thermostatic valve kit (designation C106) controls lubricating oil temperature in oil-injected rotary screw compressors. The valve modulates oil flow through the cooler based on temperature, maintaining optimal operating viscosity and preventing overheating or overcooling. Kit comprises thermostatic valve element, housing seals, and installation hardware. Constructed from copper alloy and high-temperature elastomers rated for continuous compressor discharge temperatures. Direct OEM replacement for Atlas Copco part numbers 2200599825 and 2200-5998-25. Cross-compatible with Chicago Pneumatic and Quincy rotary screw compressor platforms sharing the same thermal management architecture. Recommended replacement interval: 8,000 operating hours or 24 months. Failure modes include stuck-open condition causing low oil temperature and moisture condensation, or stuck-closed condition leading to excessive discharge temperature and automatic shutdown.
