Components of the Typical Check Valve (3) Inlet (4) OutletThe check valves are used to allow air to flow in one direction only. Air will enter the check valve through inlet (3). The air will force a spring in the body into compression and the valve will open. Air under pressure is now free to flow through the check valve.Air that is entering the check valve through outlet (4) will push the valve against a seat in the body. The flow of air is stopped.
