The Z2S10-2-3X/V SO30 is a check valve in the Z2S Check Valves series manufactured by Bosch Rexroth for hydraulic automation where load holding and leakage prevention are required. The valve uses a sandwich plate design, so it fits between subplates without extra piping. A nominal size of 10 aligns with the ISO 4401-05-05-0-05 porting pattern and the NFPA T3.5.1 D05 manifold interface, making it compatible with common CETOP 5 mounting surfaces. Both service lines A and B are blocked when pilot pressure is absent, and pilot-operated release allows controlled bidirectional flow when commanded. The poppet lifts at a cracking pressure of 3 bar, and internal passages withstand working pressures up to 350 bar, supporting high-pressure machine circuits.
The valve carries a maximum flow capacity of 160 l/min to accommodate medium-sized actuators without inducing excessive pressure drop. FKM seals are installed to maintain leakage integrity when exposed to standard hydraulic oils. The required oil cleanliness is ISO 4406 20/18/15, so filtration must limit particulate contamination to that level. No external pilot ports X or Y are provided, simplifying manifold layouts, and position monitoring hardware is not included, so downstream controls must infer spool status from pressure feedback. The unit can be mounted in any orientation, giving designers flexibility in stack assembly.
