What is a rotary screw air compressor inlet valve?

The inlet valve is one of the most important and complicated parts of a rotary screw air compressor. No part of the compressor so uniquely differentiates the various manufacturers. Each has its own proprietary design for the part because it has a major impact on the performance of your compressor.

How does a compressor inlet valve work?

Here’s how that works in your compressor. The inlet valve is the gatekeeper for your compressor. It allows air into the compression chamber, opening fully when it’s in the load portion of the cycle and closing in the unload part.

When should a compressor inlet valve be set?

The adjustable inlet valve should be set to operate within the appropriate parameters when a new compressor is installed. Generally, the pressure parameters are set up at the factory, but the installation team should check the pressure to make sure the valve did not go out of adjustment during shipping. That can happen.
