HSZ16B108-3X/AS200-BS200M00

The HSZ16B108-3X/AS200-BS200M00 sandwich plate belongs to the HSZ Sandwich Plates series and is produced by Bosch Rexroth for modular hydraulic automation. It limits system pressure in stacked valve assemblies and operates safely up to 315 bar. A direct-operated DBD relief valve vents excess pressure without pilot circuitry, and its opening point is fixed at 200 bar to protect actuators from overload. Flow channels follow the DIN 24340 A and ISO 4401 porting pattern so the plate mates with standard subplates and directional valves, supporting compact manifold construction while maintaining consistent mounting dimensions.

Pressure adjustment is carried out with a hexagon set screw, allowing maintenance staff to fine-tune the relief setting when service conditions require changes. NBR seals resist common hydraulic oils and minimize internal leakage during continuous duty cycles. The plate has no external drain or pilot connection, which simplifies installation in confined manifolds. Internal passages allow the relief function to be positioned on either Side E or Side F, giving flexibility when configuring left- or right-hand stacking arrangements within a hydraulic circuit.
