Frequently Asked Questions

Is the 91B80 valve compatible with my Gardner Denver compressor?

The 91B80 valve is designed for Gardner Denver air compressors that require this exact solenoid valve part number. It is commonly identified as a two-way, normally open solenoid valve with a 1/4 inch connection and a 120-volt, 60 Hz coil. Compatibility should always be confirmed by matching 91B80 in your parts manual and verifying your compressor model, serial number, voltage, and valve configuration before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility.

What does the 91B80 valve do?

The 91B80 is an electrically operated solenoid valve used to control pneumatic airflow within a compatible Gardner Denver compressor control system. When electrically energized or de-energized, it changes the valve position to regulate airflow through the connected circuit. This valve helps:

  • Control pneumatic signal airflow
  • Support proper compressor loading and unloading functions
  • Coordinate airflow with the electrical control system
  • Maintain reliable compressor pressure control
  • Support consistent operation during demand changes

What does normally open mean for the 91B80 valve?

The 91B80 is commonly listed as a normally open valve, meaning its airflow passage remains open when the solenoid coil is not energized. Applying electrical power changes the valve position according to the compressor control sequence.

The replacement valve must match the original:

  • Normally open configuration
  • Two-way valve design
  • 120-volt, 60 Hz electrical rating
  • 1/4 inch connection size
  • Required airflow direction

Installing a valve with the wrong configuration or voltage may prevent the compressor control system from operating correctly.

Is this an OEM part?

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

What are the signs that the 91B80 valve needs replacement?

Common symptoms include:

  • Compressor does not load or unload correctly
  • Irregular compressor cycling
  • Air leaking from the valve body or connections
  • Solenoid coil does not energize
  • Valve remains stuck open or closed
  • Unusual buzzing or excessive heat from the coil
  • Unstable control pressure
  • Damaged wiring, terminals, or valve threads

These symptoms can also be caused by wiring, pressure switches, blocked control lines, or other pneumatic components, so the 91B80 should be tested before replacement.

How difficult is it to install?

Installing the 91B80 is generally a moderate maintenance task because it involves both the compressor’s electrical and pneumatic control systems. Before installation, the compressor should be:

  • Fully shut down
  • Electrically isolated and locked out
  • Completely depressurized
  • Cooled to a safe working temperature
  • Verified with a meter to ensure electrical power is disconnected

Do you carry other parts for Gardner Denver?
