The HSZ16B550-3X/M01 sandwich plate belongs to the HSZ Sandwich Plates series and is produced by Bosch Rexroth for modular hydraulic automation. It adds pressure control to a manifold by integrating a pressure reducing valve that limits downstream pressure to protect sensitive actuators. A pilot-operated DR20K element performs the regulation, and the plate is designed for systems that operate up to 315 bar. The underside follows the DIN 24340 Form A / ISO 4401 interface, allowing direct stacking between compatible size 16 stations. Circuit access is provided through P, A, B, T, X, and Y ports so designers can route supply, work, drain, and pilot lines without extra blocks.
Physical data supports straightforward installation. The steel body measures 140 × 91 × 100 mm and weighs 9.5 kg, providing a compact footprint inside power units. Ports P, A, and B use G1/4 threads, and the Y port is tapped to the same G1/4 size for unified piping. All threaded connections comply with DIN 3852-2 (ISO 228), ensuring compatibility with common tube fittings. NBR seals identified by the M01 code prevent external leakage and withstand typical hydraulic fluids during continuous duty.
