Frequently Asked Questions

What is the Atlas Copco Blow Off Valve Assembly Replacement - 1623181080?

The Atlas Copco Blow Off Valve Assembly Replacement - 1623181080 is a valve assembly used on compatible Atlas Copco oil injected rotary screw air 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 does the 1623181080 blow off valve assembly do?

The 1623181080 is associated with the compressor’s pressure control and unloading system. A blow off or blowdown valve allows trapped internal pressure to be relieved when the compressor unloads or shuts down, helping reduce the pressure the compressor must work against during restart.

Its role can include helping:

  • Relieve trapped internal pressure
  • Support proper unloading
  • Reduce starting load on the motor
  • Control pressure during shutdown
  • Prepare the compressor for the next startup cycle

Why is depressurizing the compressor important during startup and shutdown?

An oil injected rotary screw compressor can retain pressure inside the separator vessel, airend, and related piping after unloading. If too much pressure remains when the motor tries to restart, the motor and drivetrain can experience excessive starting load.

A properly operating blowdown system helps reduce this trapped pressure before the next startup.

What are signs that the 1623181080 blow off valve may need to be replaced?

Possible symptoms of a worn, sticking, or leaking blow off valve can include:

  • Compressor remaining pressurized after shutdown
  • Difficult or heavily loaded restarts
  • Compressor failing to unload properly
  • Continuous air leakage
  • Pressure taking unusually long to bleed down
  • Valve failing to close after startup
  • Compressor struggling to build pressure
  • Repeated unload or blowdown related faults

These symptoms can also be caused by control solenoids, pneumatic tubing, minimum pressure valves, inlet valves, or other control components, so the complete unloading system should be diagnosed before replacing the valve.

Is this an OEM part?

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

Do you carry other parts for Atlas Copco?

Absolutely. We stock a range of air filters, oil filters, valves, synthetic oils, and many other maintenance parts to help you keep your Atlas Copco compressor running reliably. If you don’t see what you need, just ask.

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.
