The Hyvair C20-16FS-70 is a steel inline check valve from the C20 series, built with 1 in (SAE-16) female SAE straight thread O-ring boss ports. Flow passes freely in one direction. Reverse flow is blocked. The valve is rated for a maximum operating pressure of 3000 psi.
O-ring boss ports seal with an O-ring on the fitting that compresses against the port face, instead of relying on tapered threads. The joint can be made up without thread sealant, and the straight thread lets you position the fitting before tightening.
Cracking pressure is 70 psi (4.8 bar) at 1 gpm. The check stays seated until inlet pressure reaches that point, then opens for forward flow. A higher cracking pressure like this keeps the valve closed against low upstream pressure. A flow direction arrow on the body marks the free flow path for installation.
Run the C20-16FS-70 on petroleum based fluid, ISO VG32 to 68. Keep fluid temperature at or below 180 °F and cold start viscosity at or below 250 SUS. Filter the system to 10 micron to protect the seat and keep the check closing cleanly.
