The HSZ06A426-1X/AALI3-BALH3M00 sandwich plate is part of the HSZ Sandwich Plates series from Bosch Rexroth and is used in hydraulic automation to link functional layers inside a manifold. Its vertically stackable design lets it sit between adjacent plates without additional fittings, and interface size 6 fixes the footprint within standard stacks. A porting pattern that meets DIN 24340 A and ISO 4401 aligns internal galleries with neighboring sections, while channels A and B are secured to control flow between those passages. The plate is produced without an external connection so every port communicates through the stack, and compact dimensions of 140 × 44 × 50 mm permit installation in space-limited power units.
The assembly tolerates operating pressures up to 315 bar for use in medium-pressure circuits, and an integrated CBC-LN valve occupies sides E and F to provide the required logic function without separate components. Its mounting cavity is R/T-11A, allowing fast cartridge exchange if service is needed. Fluid sealing relies on NBR material, while a Fe/Zn8/Cn/T0 zinc coating guards the steel body against corrosion. The plate weighs 2.3 kg for manageable handling during maintenance, and it is supplied without a locating hole so bolt placement can be chosen to match the manifold layout.
