HSZ06A660-4X/MHSU2K-D25M01

The HSZ06A660-4X/MHSU2K-D25M01 sandwich plate belongs to the HSZ Sandwich Plates series produced by Bosch Rexroth for hydraulic automation stacks. It is inserted between subplates and directional valves to introduce a fixed orifice and pressure rating without altering manifold geometry. The plate is built to size 6, so it fits valve interfaces used in compact mobile or industrial power units. A porting pattern that follows DIN 24340 A and ISO 4401 allows direct stacking with other standardized components, streamlining assembly. The maximum operating pressure is 315 bar, enabling the plate to function in high-pressure supply lines without deformation. A 2.5 mm orifice establishes a defined restriction, which limits pilot flow for controlled actuation of downstream elements.

The body measures 115 × 44 × 40 mm, so it occupies minimal space in a valve bank while still providing the required flow path. Its weight of 1.02 kg keeps the overall manifold mass low, easing installation by a single technician. Port P is positioned on side F, which helps align the main supply line with adjacent plates, and a G1/4 thread on this port accepts common BSP fittings. Port X is placed on side E for separate pilot or drain connections, and it also uses a G1/4 thread to maintain consistent tooling across ports. These physical details ensure straightforward routing and secure connections within the hydraulic circuit.
