Is the 02250144-327 thermal valve kit compatible with my Sullair compressor?
The 02250144-327 thermal valve kit is designed for select Sullair compressor applications that require this exact part number. Compatibility should always be confirmed by matching the part number in your compressor’s parts manual or by verifying your 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 a thermal valve do?
A thermal valve helps regulate the oil temperature inside the compressor by controlling whether oil flows through the cooler or bypasses it. This allows the compressor to reach proper operating temperature quickly and maintain stable conditions during operation. Thermal valve kits are designed to support proper lubrication, reduce oil foaming, and protect internal components.
Why is it important to replace a faulty thermal valve?
A faulty thermal valve can cause the compressor to run too hot or too cold, which can lead to poor lubrication, moisture buildup, or reduced efficiency. Replacing the thermal valve helps maintain proper oil temperature control and supports more reliable compressor operation.
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 valve kit.
What are the signs that the thermal valve needs to be replaced?
Common signs include overheating, low operating temperature, excessive moisture in the system, or inconsistent performance. If the compressor is not maintaining stable operating temperature, the thermal valve may need to be inspected and replaced.
How difficult is it to install?
Thermal valve replacement is a mechanical maintenance task that involves removing the existing valve assembly and installing the replacement kit. Because this component is part of the compressor’s oil and cooling system, the machine should always be shut down, isolated, and depressurized before performing service.
