The HSZ16B207-3X/05-AS200-BS200M00 sandwich plate belongs to the HSZ Sandwich Plates series from Bosch Rexroth and is intended for modular hydraulic automation stacks. An integrated M-SR cartridge check valve allows free flow in one direction while blocking reverse flow until the circuit reaches its 1.0 bar cracking pressure. The mounting type is a sandwich plate, so the unit is clamped between adjacent valve layers without additional brackets. Six internal ports—P, A, B, T, X, and Y—route pressure, return, and pilot lines through the stack to simplify manifold design. Code 00 indicates no external connections, which reduces piping and potential leak paths. NBR seal material provides compatibility with common hydraulic oils and maintains tight sealing under temperature changes.
The plate withstands a maximum operating pressure of 315 bar, making it suitable for high-pressure industrial circuits. A direct-operated DBD pressure relief valve discharges excess fluid when system pressure rises, protecting downstream components. Port A is safeguarded at a preset 200 bar, and port B is likewise limited to 200 bar, keeping both actuator lines within identical limits. Each relief setting uses a set screw adjustment, enabling service personnel to fine-tune pressure thresholds without removing the plate from the stack. These pressure control features work alongside the check valve and sealed internal passages to maintain stable, leak-free operation in automated hydraulic machinery.
