HSZ10A611-3X/M00

The HSZ10A611-3X/M00 hydraulic sandwich plate belongs to the HSZ Sandwich Plates series from Bosch Rexroth and is intended for modular valve stacks in automated hydraulic circuits. The unit follows a sandwich plate stacking design, enabling compact integration between adjacent valve layers. With a nominal size of 10, it matches medium-flow manifold layouts common to industrial machinery. Its direct-operated arrangement, identified as design code A, allows the internal spool to respond directly to pressure changes without pilot assistance. Mounting conforms to ISO 4401 size 05, so the plate seats on standard subplates and adjoining components without machining. The porting pattern is specified as ISO 4401-05-04-0-94, ensuring that pressure, tank, and actuator passages align accurately across the stack, and all port faces comply with DIN 24340 form A, which unifies port location and bolt spacing among European hydraulic elements.

It accommodates system pressures up to 315 bar, allowing the assembly to function in high-pressure circuits such as presses and injection machines. NBR seals designated by code M are installed to provide oil compatibility with common mineral-based fluids while retaining elasticity over temperature changes. Surface protection is achieved through a Fe/Zn8/Cn/T0 zinc coating in accordance with DIN 50979, resisting corrosion during prolonged exposure to hydraulic oil and moist air. Because the line connection code is 00, the plate has no external threaded ports; all flow paths are internal to the stack, reducing leak points. There are no pilot ports, so actuation forces are delivered directly through the main passages without auxiliary control lines.
