The Hyvair C20-6FS-7 is a 3/8 in inline check valve with female SAE O-ring boss (ORB) ports, part of the C20 Series. It allows flow in one direction and blocks reverse flow.
SAE ORB ports seal with an O-ring on the male fitting rather than on the threads, which makes them a common choice for leak-resistant hydraulic connections. The steel body is rated to 3000 psi (210 bar) working pressure and 180°F.
The standard cracking pressure is 7 psi, with other cracking settings available. Low cracking pressure means low pressure drop through the valve, which matters in sensitive control circuits and instrumentation lines.
In service, the valve prevents reverse flow and system back-drain, protecting pumps, actuators and downstream components. The compact form suits mobile hydraulics, industrial machinery and instrument protection lines where a small 3/8 in check valve has to hold up to full system pressure. Install it with standard male SAE ORB fittings and confirm flow direction before startup.
