The SV30GA4-4X/V/12 check valve is produced by Bosch Rexroth as part of the Hy-Check Valves series. It is installed in hydraulic automation circuits to block reverse flow and open when pilot pressure is available. The valve has a nominal size of 32 that determines its passage area for medium to high flow rates. Its housing withstands a maximum operating pressure of 315 bar for use in high-pressure systems. A cracking pressure of 10 bar ensures the poppet lifts only after the inlet reaches that value. The control area A1 measures 5.72 cm², defining the hydraulic force acting on the poppet. A built-in pre-opening feature reduces pressure peaks during initial flow. Connection is made through threaded ports that follow the UNF/UN profile specified in ANSI/ASME B1.1, and the unit weighs 10 kg, which must be supported by the manifold or piping.
The valve operates with hydraulic fluids whose viscosity ranges from 2.8 to 500 mm²/s, covering most mineral oil grades. Fluid temperature may vary between −15 and +80 °C, and the same −15 to +80 °C ambient range applies for versions sealed with FKM. It carries a maximum flow capacity of 550 l/min to serve high-volume lines. The pilot stage responds to pressures from 5 to 315 bar, and 19.27 cm³ of oil is required at port X to shift the poppet. Pilot oil returns internally, so no external drain is needed. System cleanliness must reach ISO 4406 class 20/18/15 to protect internal surfaces.
