NON RETURN VALVE FOR SG COMP06/07

AirCraft Non-Return Valve For SG COMP06 & SG COMP07 (SG COMP06-03)

At a Glance: Compressor non-return (check) valve—prevents backflow and helps keep tank pressure stable.

A non-return valve (also called a check valve) is a small part with a big job: it allows air to flow into the tank, but stops it from flowing back toward the compressor head. The AirCraft SG COMP06-03 Non-Return Valve is designed for the SG COMP06 and SG COMP07 compressor range. If a compressor struggles to restart under pressure, leaks air back through the line, or loses tank pressure faster than expected, a worn check valve is often the culprit. Replacing the non-return valve helps maintain stored pressure, supports smoother cycling, and protects the compressor mechanism from backflow stress.
