Product Overview
The Rexroth HSZ 06 A106-3X/M00 (Material Number: R900516519) is a precision-engineered hydraulic sandwich plate valve block designed for modular system integration within industrial hydraulic circuits. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this component belongs to the HSZ series of intermediate sandwich plates, which are mounted between a directional control valve and its subplate to provide additional flow control or circuit logic functions. The HSZ 06 size designation corresponds to a nominal NG6 (CETOP 3 / ISO 4401-03) interface, ensuring direct compatibility with standard industrial valve stacks. The “A106” flow control cartridge integrated into this block provides a fixed or adjustable throttling function, enabling precise regulation of actuator speed or flow distribution within a multi-function manifold assembly. The “3X” series designation indicates a proven, field-tested generation of Rexroth modular valve technology, while the “M00” suffix denotes the standard configuration without special options. This sandwich plate valve block plays a critical role in compacting complex hydraulic control architectures, reducing piping, minimizing leak points, and enabling rapid maintenance or circuit modification in high-demand industrial machinery.
