The HSZ06A433-3X/PRDB-LDN-K1UG24N9K4M01 sandwich plate is produced by Bosch Rexroth for the HSZ Sandwich Plates series, serving as a pressure-reducing and directional control element in hydraulic automation stacks. It incorporates a 3/2 spool valve to switch flow paths when energized, and the 24 V DC solenoid suits common machine control voltages. Coil power of 22 W keeps heat generation manageable while still delivering reliable actuation force. A DIN EN 175301-803 (2+PE) connector simplifies wiring and maintains standardized pin assignment. The concealed manual override identified as N9 allows service technicians to shift the spool without energizing the coil. Set pressure option Code D is preset to 14 bar at the factory so the plate can limit circuit pressure immediately after installation. A hex socket setscrew marked L provides fine external adjustment of the regulated value when tuning the system on site.
The casting measures 170 mm in length, 70 mm in height, and 44 mm in width, dimensions that fit within standard CETOP 06 stacking envelopes. An MG 1/4 port size aligns with typical pilot lines and minimizes adapter requirements during assembly. NBR sealing is selected for compatibility with conventional mineral hydraulic fluids and to resist compression set during continuous duty. The total weight of 4.5 kg permits manual handling while providing sufficient mass to stabilize the manifold against vibration. The rectangular footprint leaves room on adjacent faces for mounting additional valve slices, and straight flow paths are machined through the body to keep pressure drop low in multi-station systems.
