Frequently Asked Questions

What is the Sullair Thermal Valve Kit Replacement - 02250124-404?

The Sullair Thermal Valve Kit Replacement - 02250124-404 is the replacement thermal valve element used in compatible Sullair rotary screw compressor fluid cooling systems.

Compatibility should always be confirmed by checking your manual and verifying the model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 02250124-404 thermal valve element do?

The thermal valve element helps regulate compressor fluid temperature by controlling whether lubricant flows through the oil cooler or bypasses it.

When the compressor fluid is cold, the thermal valve allows more oil to bypass the cooler so the machine can reach operating temperature. As fluid temperature approaches the valve’s operating range, the valve changes position and directs more lubricant through the oil cooler.

This helps:

  • Bring the compressor up to operating temperature efficiently
  • Prevent excessive compressor fluid temperature
  • Maintain proper lubricant viscosity
  • Reduce condensation risk
  • Support proper airend lubrication
  • Protect the compressor cooling system

What temperature is the 02250124-404 thermal valve set for?

The 02250124-404 is documented with a 160°F setting. This corresponds to approximately 71°C.

What are signs that the 02250124-404 may need to be replaced?

Possible symptoms include:

  • Compressor fluid temperature running unusually high
  • Compressor consistently operating too cool
  • Temperature fluctuating abnormally
  • High temperature shutdowns
  • Oil cooler not warming when expected
  • Oil cooler warming too quickly after a cold start
  • Excessive condensation in the compressor fluid
  • Varnish or sludge in the thermal valve area

These symptoms should be diagnosed alongside the cooler, fluid level, hoses, and thermal bypass manifold.

Is this an OEM part?

This is an OEM-equivalent replacement thermal valve kit designed to meet the same performance standards as the original Sullair thermal valve kit.
