Gardner Denver Thermal Valve Replacement - 90AR1179

Maintain proper compressor oil temperature and dependable cooling performance with the Gardner Denver Thermal Valve Replacement - 90AR1179, a 160°F thermostatic valve designed for compatible Gardner Denver rotary screw compressors. This valve helps regulate lubricant flow through the cooling circuit so the compressor can warm up properly while still receiving adequate cooling as operating temperature increases. Replacing a sticking, worn, or failed thermal valve can help correct overheating, unstable oil temperatures, and poor cooling performance.

  • 160°F Thermal Valve: Gardner Denver documentation identifies 90AR1179 as the standard 160°F thermal valve for compatible compressor applications.
  • Controls Oil Cooling Flow: Helps regulate when compressor lubricant is routed through the cooler to maintain proper operating temperature.
  • 1 Inch, 150 PSI Design: Gardner Denver identifies the valve as a 1 inch aluminum thermal valve rated to 150 PSI.
  • OEM Compatible Replacement: Built as a replacement for Gardner Denver part number 90AR1179 to support proper fitment and dependable temperature regulation.

Frequently Asked Questions

What is the Gardner Denver Thermal Valve Replacement - 90AR1179?

The Gardner Denver Thermal Valve Replacement - 90AR1179 is a thermostatic valve used in the compressor oil circuit.

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 90AR1179 thermal valve do?

The 90AR1179 helps maintain the proper operating temperature of the compressor lubricant. Depending on oil temperature, the valve directs oil either:

  • Through the oil cooler for additional cooling
  • Through the oil bypass circuit while the lubricant is still warming up
  • Between the two paths as necessary to maintain the intended operating temperature

This temperature regulation is important for proper lubrication and overall compressor performance.

What is the temperature rating of the 90AR1179 thermal valve?

The 90AR1179 is the 160°F standard thermal valve in documented Gardner Denver applications. 

How can I tell if my thermal valve may need to be replaced?

A malfunctioning thermal valve can interfere with normal oil temperature regulation. Possible symptoms may include:

  • Compressor oil temperature running unusually high
  • Compressor taking too long to reach normal operating temperature
  • Oil continuously bypassing the cooler
  • Oil being routed through the cooler when it should still be warming
  • Temperature related shutdowns or alarms
  • Irregular lubricant temperature during otherwise normal operation

Because similar symptoms can also be caused by restricted coolers, low lubricant levels, airflow problems, or other cooling system issues, the thermal valve should be properly diagnosed before replacement.

Is this an OEM part?

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

Do you carry other parts for Gardner Denver?

Absolutely. We stock a range of air filters, oil filters, separators, synthetic oils, and many other maintenance parts for Gardner Denver equipment. If you don’t see what you need, just ask and we’ll help you find it.

How do I know which oil to use in my Gardner Denver compressor?

Stationary rotary screw compressors may have specific oil requirements that differ from reciprocating or portable units. To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Gardner Denver Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
