The Bosch Rexroth HSZ 10 is a sandwich (intermediate) plate valve designed for modular hydraulic valve stacks. It is installed between the subplate and the directional control valve to add specific hydraulic logic or pressure-related functions without external piping.
This plate follows the ISO 4401-05 / CETOP 5 / NG10 mounting standard, making it fully compatible with Rexroth and other CETOP-5 directional valves.
•Used to create pressure control, logic interlocking, or flow conditioning
•Designed for stacked valve assemblies
Function Code – B035
•“B” configuration indicates logic/pressure-related control on actuator lines (A/B ports)
•Typically used for:
