The Hyvair C20-20FP-70 is an inline check valve in the C20 series, with a steel body and 1-1/4 in female NPT ports. It lets flow pass in one direction and stops it in the other. The valve is rated to a maximum operating pressure of 3000 psi.
This model has a 70 psi (4.8 bar) cracking pressure at 1 gpm. Cracking pressure is the point where inlet pressure overcomes the spring and the check opens. With a 70 psi setting, the valve holds closed until upstream pressure clearly builds, rather than opening at the first push of flow.
Ports are 1-1/4 in female NPT for male tapered pipe thread fittings. A flow direction arrow on the body shows the free flow path, which makes correct installation easy to check at a glance.
Use petroleum based fluid in the ISO VG32 to 68 range. Maximum fluid temperature is 180 °F, and maximum cold start viscosity is 250 SUS. Recommended filtration is 10 micron. Holding that cleanliness level keeps particles from lodging at the seat, where they could stop the check from closing fully.
