Frequently Asked Questions

Is the 1ABL507 discharge valve compatible with my Gardner Denver compressor?

The 1ABL507 is a Gardner Denver high-pressure discharge valve assembly used on compatible reciprocating air compressors. Always verify 1ABL507 in the compressor parts manual and confirm 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 1ABL507 discharge valve do?

The 1ABL507 controls the flow of compressed air leaving the compressor’s high-pressure cylinder.

During the compression stroke, the discharge valve opens when cylinder pressure becomes high enough to overcome downstream pressure and spring force.

It then closes to prevent compressed air from flowing back into the cylinder.

Can the compressor continue running with a damaged discharge valve?

It may continue to run, but doing so is not recommended.

A failed valve can contribute to:

  • Poor compressor performance
  • Excessive heat
  • Additional valve damage
  • Cylinder damage
  • Increased operating cost

A suspected valve problem should be inspected promptly.

What are the signs that the 1ABL507 discharge valve needs to be replaced?

Common signs include:

  • Reduced compressor capacity
  • Longer time to build pressure
  • Compressor struggles to reach normal discharge pressure
  • High-pressure cylinder runs hotter than normal
  • Abnormal valve noise
  • Air leakage through the discharge valve
  • Valve disc is cracked, warped, or damaged
  • Valve spring is broken or weak
  • Valve seat is damaged
  • Carbon or deposit buildup interferes with valve movement

Because these symptoms can also come from piston rings, inlet valves, intercooler problems, or cylinder wear, the full high-pressure stage should be inspected.

Is this an OEM part?

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

How difficult is it to install?

Replacing the 1ABL507 is generally a moderate to advanced mechanical repair because it involves opening the compressor’s high-pressure cylinder valve assembly. Because incorrect valve installation can affect compression performance or cause internal damage, this repair is best performed by someone familiar with large reciprocating compressor valve service.

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.
