Maintain proper compressor oil temperature and dependable cooling performance with the Atlas Copco Thermal Valve Replacement - 1622706405, a 71°C thermostatic valve designed for compatible Atlas Copco oil-injected rotary screw compressors. This valve helps control when compressor lubricant is routed through the oil cooler, allowing the system to warm up properly while preventing excessive operating temperatures. Replacing a sticking or failed thermal valve can help correct overheating, unstable oil temperatures, and poor cooling performance.

  • 71°C Thermostatic Valve: Designed to regulate compressor lubricant temperature around a 71°C operating threshold in compatible applications.
  • Controls Oil Cooler Flow: Directs lubricant through the cooler as operating temperature rises to help maintain proper thermal balance.
  • Helps Prevent Overheating: Proper valve operation supports effective cooling and helps protect lubricant and internal compressor components from excessive heat.
  • OEM Compatible Replacement: Built as a replacement for Atlas Copco part number 1622706405 for compatible oil-injected screw compressors.

Help maintain proper oil temperature, efficient cooling, and dependable compressor operation with the Atlas Copco Thermal Valve Replacement - 1622706405 for compatible Atlas Copco rotary screw compressors.

Frequently Asked Questions

What is the Atlas Copco 1622706405?

The 1622706405 is a thermostatic valve / thermal valve used in the compressor oil-cooling circuit of compatible Atlas Copco oil-injected rotary screw compressors.

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 temperature is the 1622706405 thermal valve rated for?

The 1622706405 is rated at:

71°C / approximately 160°F

Atlas Copco identifies it directly as a 71°C thermostatic valve.

What does the 1622706405 thermal valve do?

The thermal valve helps regulate compressor oil temperature.

When the oil is relatively cool, the valve allows oil to bypass much of the oil cooler so the compressor can reach normal operating temperature efficiently.

As the oil heats up, the valve changes position and directs more lubricant through the cooler.

This helps maintain a suitable compressor operating temperature.

What are the signs that the 1622706405 thermal valve may need to be replaced?

Common symptoms include:

  • Compressor repeatedly shuts down on high temperature
  • Compressor oil runs hotter than normal
  • Oil cooler remains cool while compressor temperature rises
  • Compressor takes unusually long to reach normal operating temperature
  • Oil stays excessively cool during operation
  • Thermal valve sticks in one position
  • Valve reaches its scheduled maintenance interval

Diagnosis should include the complete cooling system before replacing the valve.

Is this an OEM part?

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

Do you carry other parts for Atlas Copco?

Absolutely. We stock a range of air filters, oil filters, separators, synthetic oils, and many other maintenance parts for Atlas Copco 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 Atlas Copco 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 Atlas Copco Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
