AirCraft Non-Return Valve SG-COMP06-45
At a Glance: One-way check valve with threaded connection to stop air flowing back into the compressor line.
The AirCraft SG-COMP06-45 Non-Return Valve (also known as a check valve) is a small but crucial part in a compressor system. Its job is simple and brilliant: it lets air flow in one direction and blocks it from flowing back the other way. That means your system can build pressure efficiently while helping protect the compressor and associated components from backflow and pressure kick-back. If your compressor struggles to start, leaks air back through the line, or you notice pressure dropping unexpectedly after shutdown, a worn non-return valve is often the culprit. Replacing it helps restore proper pressure behaviour and smoother operation.
Fitted in the air line path where backflow must be prevented, this valve supports reliable pressure retention and correct system cycling. Match the Cat No. SG-COMP06-45 to your compressor’s parts list or existing valve for correct fitment.
