Frequently Asked Questions

Is the 91B143 solenoid valve compatible with my Gardner Denver compressor?

The 91B143 is a Gardner Denver two-way, normally open solenoid valve for compatible air compressor control systems. Compatibility should always be confirmed by matching 91B143 in your compressor manual and verifying the model, serial number, voltage, port configuration, and wiring connection before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 91B143 solenoid valve do?

The 91B143 is an electrically operated valve that controls airflow within the compressor’s pneumatic control system. A normally open solenoid valve allows airflow through its normal, de-energized position and changes flow when electrical power is applied.

Depending on the compressor configuration, it may help control:

  • Load and unload operation
  • Control-air routing
  • Venting or pressure-release functions
  • Inlet valve control
  • Compressor start and stop sequencing

Why is replacing the 91B143 important?

A properly functioning 91B143 helps maintain:

  • Reliable pneumatic control operation
  • Consistent loading and unloading
  • Proper pressure release when required
  • Stable compressor cycling
  • Reduced risk of control-related faults

A failed or sticking solenoid valve can interrupt control airflow and contribute to operating issues such as improper loading, pressure remaining in the system, air leaks, or erratic cycling.

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 91B143 solenoid valve may need replacement?

Common symptoms can include:

  • Compressor failing to load or unload correctly
  • Air leaking from the valve or control tubing
  • Irregular compressor cycling
  • Pressure remaining in the system after shutdown
  • Faults related to pneumatic control operation
  • Solenoid coil not energizing
  • Clicking without proper valve movement
  • Damaged wiring, connectors, or valve body
  • Failed continuity or voltage testing

These symptoms can also be caused by control-air leaks, damaged tubing, wiring faults, a failed relay, or another valve issue, so the full control circuit should be inspected before replacing the 91B143.

How difficult is it to install?

Installing the 91B143 is generally a moderate maintenance task because it involves both electrical wiring and the compressor’s pneumatic control circuit.

Before service, the compressor should be:

  • Fully shut down
  • Electrically locked out
  • Completely depressurized
  • Cooled to a safe working temperature
  • Verified so no stored air pressure remains in the control lines

Installation typically involves documenting wire and tubing locations, disconnecting the original valve, installing the replacement 91B143, reconnecting the control lines and wiring, and checking for leaks and proper valve operation after startup.

Do you carry other parts for Gardner Denver?

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.
