The Hyvair C20-16FP-70 is a C20 series inline check valve with a steel body and 1 in female NPT ports. It passes flow freely in one direction and blocks flow in the reverse direction, keeping fluid from running back through the line. Maximum operating pressure is 3000 psi.
Cracking pressure is 70 psi (4.8 bar), measured at 1 gpm. Cracking pressure is the inlet pressure needed to unseat the check and start forward flow. At 70 psi, the valve stays closed until upstream pressure builds past a firm spring setting, which suits circuits where the check should hold back flow until that threshold is reached.
The 1 in female NPT ports accept male tapered pipe thread fittings. A flow direction arrow on the body shows which way the valve passes flow, so orientation is clear when you install it.
For fluid, use petroleum based oil in the ISO VG32 to 68 range. Maximum fluid temperature is 180 °F, and cold start viscosity should not exceed 250 SUS. Recommended filtration is 10 micron, which keeps contamination off the seat so the check can close fully.
