The Hyvair C20-20FS-70 is a C20 series inline check valve with a steel body and 1-1/4 in (SAE-20) female SAE straight thread O-ring boss ports. Flow moves freely one way and is blocked the other way. The valve is rated to 3000 psi maximum operating pressure.
Cracking pressure is 70 psi (4.8 bar) at 1 gpm. The check will not open until inlet pressure reaches that level. Compared with a light spring check, a 70 psi setting holds the line closed against low pressure and only passes flow once upstream pressure builds.
The O-ring boss ports use straight threads with an O-ring seal at the port face. Fittings seal without thread sealant and can be removed and reinstalled during maintenance. A flow direction arrow on the body shows the free flow direction for installation.
Specify petroleum based fluid in the ISO VG32 to 68 range. Maximum fluid temperature is 180 °F, and cold start viscosity should stay at or below 250 SUS. Recommended filtration is 10 micron, which keeps contamination away from the seat so the valve can close tight in the reverse direction.
