HSZ06A431-1X/LI3M00

The HSZ06A431-1X/LI3M00 sandwich plate belongs to the HSZ Sandwich Plates series and is produced by Bosch Rexroth for stacked hydraulic manifolds. It routes pressure, return, and pilot lines between subplates in automation circuits where compact assembly is required. An interface size of 6 aligns the plate with NG6 directional valves so that flow paths match without adapters. The porting pattern follows DIN 24340 A and ISO 4401, enabling interchange with standardized subplates worldwide. A valve side designated as F places the functional cavities on the correct face for compatible control elements. The mounting cavity type R/T-11A provides the recess needed to seat logical elements within the plate body. Physical dimensions of 140 mm in length, 44 mm in width, and 50 mm in height fit the plate into compact manifold stacks without exceeding common block envelopes.

The plate withstands a maximum operating pressure of 315 bar, allowing it to serve in high-pressure industrial power units. A Fe/Zn8/Cn/T0 coating adds a zinc layer that shields the steel body from corrosion during continuous fluid exposure. NBR seals are supplied to contain mineral oil and prevent external leakage at plate joints. The design specifies no external connection ports, identified as option 00, so all flow paths are internal to the sandwich stack. An assembled weight of 2.2 kg facilitates manual handling during maintenance or reconfiguration of modular manifolds. This pressure capacity supports servo cylinders without risk of plate deformation. Combined with the corrosion protection and internal routing, the plate maintains long service intervals under cyclic load.
