Frequently Asked Questions

Is the 2204154601 check valve compatible with my Atlas Copco compressor?

The 2204154601 is an Atlas Copco check valve for compatible oil-injected screw compressor applications. Atlas Copco identifies 2204154601 as a G1/8 check valve with 6x4 connection and 0.7 nozzle for an oil-injected screw compressor. Compatibility should always be confirmed by matching 2204154601 in your compressor manual and verifying the model, serial number, valve location, thread size, tube connection, nozzle size, flow direction, and pressure circuit before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 2204154601 check valve do?

The 2204154601 allows flow in one direction while blocking reverse flow. Depending on the compressor configuration, it helps:

  • Prevent air or oil backflow
  • Support proper compressor control-system operation
  • Help maintain correct flow direction
  • Protect connected tubing, valves, and compressor components
  • Support reliable oil-injected screw compressor performance

Why is replacing the 2204154601 important?

A properly functioning 2204154601 helps maintain:

  • Correct one-way flow
  • Stable compressor operation
  • Reduced backflow after shutdown
  • Better protection for connected components
  • More reliable pressure and fluid control

A leaking, blocked, stuck, contaminated, or damaged check valve can allow reverse flow, create pressure instability, or cause abnormal compressor behavior.

What are the signs that the 2204154601 check valve may need replacement?

Common signs can include:

  • Air or oil flowing backward through the line
  • Compressor pressure bleeding down faster than normal
  • Hissing or leaking near the valve after shutdown
  • Oil carryover or scavenge-line issues in applicable systems
  • Compressor struggling to build or maintain pressure
  • Valve sticking open or closed
  • Contamination or debris found inside the valve
  • Abnormal pressure behavior after other system issues have been checked

These symptoms can also be caused by control-line leaks, minimum pressure valve issues, solenoid valve problems, scavenge-line restrictions, separator issues, or incorrect installation. Inspect the full system before replacing only the 2204154601.

Is this an OEM part?

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

How difficult is it to install?

Installing the 2204154601 is generally a simple to moderate maintenance task, depending on valve location and access.

Before service, the compressor should be:

  • Fully shut down
  • Electrically locked out if required
  • Completely depressurized
  • Cooled to a safe working temperature
  • Positioned to contain any oil or condensate released during service
  • Verified so no stored pressure remains in the connected tubing or valve body
  • Documented so tubing and flow direction can be reinstalled correctly

Installation typically involves identifying the existing valve location, marking tubing connections, removing the old valve, installing the replacement 2204154601 in the correct flow direction, checking fittings, and confirming there are no leaks after startup.

Do you carry other parts for Atlas Copco?
