The SL10PB2-4X/V check valve is produced by Bosch Rexroth within the Hy-Check Valves series and is intended to block reverse flow in hydraulic automation while opening on a pilot signal. It matches NG10 cavities and uses the ISO 5781-06-07-0-16 porting pattern, allowing direct subplate mounting without additional adapters. Rated for 350 bar, the housing tolerates typical system pressures, and a cracking pressure of 3.0 bar keeps the poppet seated until line pressure rises above that threshold. A maximum pilot pressure of 350 bar prevents overstress of internal parts, whereas a minimum pilot pressure of 5 bar is required to shift the element reliably.
The control area at port A1 is 1.33 cm² and at port A3 is 3.8 cm², establishing the differential that lifts the poppet once pilot force is applied. Pilot oil returns externally, with 2.5 cm³ of volume at port X and 2.0 cm³ at port Y to ensure quick response. An FKM seal accommodates common hydraulic fluids, and the design omits a pre-opening feature so flow begins only after the seat is fully cleared. Fluid cleanliness must meet ISO 4406 20/18/15 to avoid wear, and the assembly weight of 1.8 kg simplifies handling during installation or service.
