Check valves allow compressed air to flow in one direction while preventing it from flowing back. In an air system they protect the compressor from reverse pressure at shutdown, hold pressure in a receiver, and keep separate air sources from feeding into one another. Reliable one-way flow is essential for safe, efficient operation.

Selecting the correct size and pressure rating ensures a positive seal with minimal restriction. Explore related control components in our valves collection, and find the connectors to install them in our air pipe and fittings selection.
