The Hyvair C20-12FS-7 is a 3/4 in inline check valve with female SAE ORB ports. Steel C20 Series construction gives unidirectional flow control and non-return protection in hydraulic systems.
Ratings are 3000 psi (210 bar) maximum working pressure, a standard 7 psi cracking pressure, and 180°F (82.2°C) maximum temperature. A 70 psi cracking option is available on larger sizes.
Operating recommendations call for petroleum-based fluids, ISO VG32 to 68, with 10 micron filtration. Cold-start viscosity capability reaches 250 SUS. Following those fluid and filtration guidelines helps the valve seal consistently over its service life.
The low cracking pressure gives quick system response. In the circuit, the valve stops backflow and protects actuators and directional control components from reverse flow. Low cracking pressure also keeps pressure loss small in the forward direction, so the valve adds little restriction to the line it protects.
SAE ORB porting and the compact C20 body make installation and retrofits simple on mobile equipment, industrial power units and other hydraulic circuits that run at up to 3000 psi and need consistent sealing.
