Frequently Asked Questions

Is the 91B81 solenoid valve compatible with my Gardner Denver compressor?

The 91B81 solenoid valve is designed for Gardner Denver compressor applications that require this exact part number. Compatibility should always be confirmed by matching 91B81 in your compressor’s parts manual or by verifying your 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 91B81 solenoid valve do?

The 91B81 is a solenoid valve, which means it uses an electrical signal to open or close and control the flow of air or fluid within the compressor. Solenoid valves are commonly used in unloading, pressure control, and system regulation functions, helping the compressor operate properly and respond to control inputs.

Why is it important to replace a faulty solenoid valve?

A faulty solenoid valve can interfere with how the compressor controls airflow, pressure, or unloading functions. This can lead to inconsistent performance or improper system operation. Replacing the valve helps restore proper control response and supports more reliable compressor operation. 

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 valve.

What are the signs that the 91B81 solenoid valve needs to be replaced?

Common signs include failure to actuate, air leaks, inconsistent compressor behavior, electrical coil issues, or problems with system response during operation. If the valve is not opening or closing as expected, it should be inspected and replaced as needed. 

How difficult is it to install?

Solenoid valve replacement is generally a mechanical and electrical service task. In most cases, the old valve is removed and the replacement is installed with the correct air connections and electrical wiring. Because this part is part of the compressor’s control and pressurized system, the machine should always be shut down, isolated, and fully depressurized before service is performed.

Do you carry other parts for Gardner Denver compressors?

Absolutely. We stock air filters, oil filters, belts, valves, intercoolers, aftercoolers, lubricants, rebuild parts, and more for Gardner Denver compressors. 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.
