HSZ22B187-3X/M00

The HSZ22B187-3X/M00 sandwich plate is produced by Bosch Rexroth as part of the HSZ Sandwich Plates series. It serves as an interface element within hydraulic automation, allowing valve sections to be stacked without external pipes. The design follows the sandwich plate format so that internal passages align directly between adjoining modules. Fluid access is handled through the integrated P, A, B, T, X, and Y ports, giving supply, work, return, and pilot lines dedicated channels. The assembly tolerates operating pressures up to 315 bar, supporting systems that require stable medium-pressure performance. There are no external connections, which simplifies mounting by keeping all flow paths contained inside the plate body.

The plate measures 225 mm in length, 117 mm in width, and 140 mm in height, defining the overall footprint for manifold designers. The height value also fixes the stack thickness, ensuring predictable spacing between clamped components. An NBR seal set is used, giving resistance to standard hydraulic oils and securing leak-free joints between neighboring plates. The length dimension maintains uniform port alignment across the stack, while the width keeps the centerlines consistent for bolt patterns. These dimensional and sealing features support reliable operation under hydraulic load and reduce assembly time in modular builds. The material choice assists long service intervals by retaining elasticity over repeated pressure cycles.
