The Hyvair C20-24FS-70 is a C20 series steel inline check valve with 1-1/2 in (SAE-24) female SAE straight thread O-ring boss ports. It allows free flow one way and blocks flow the other way. Maximum operating pressure is 3000 psi.
Cracking pressure is 70 psi (4.8 bar) at 1 gpm. That is the inlet pressure needed to push the check off its seat. With a 70 psi spring setting, the valve stays shut under light upstream pressure and opens only after pressure rises to that level.
The SAE-24 O-ring boss ports seal on an O-ring at the port face, with straight threads holding the fitting in place. Fittings go in without thread sealant and can be serviced and reinstalled. A flow direction arrow on the body confirms orientation at installation.
Use petroleum based fluid in the ISO VG32 to 68 range. Maximum fluid temperature is 180 °F, and cold start viscosity should be 250 SUS or lower. Filter the system to 10 micron. Clean oil keeps contamination off the seat, which lets the check seal completely in the blocked direction.
