Bosch Rexroth ZDB10VP1-4X/100V sandwich pressure-relief valve

Bosch Rexroth ZDB10VP1-4X/100V is a size 10 sandwich pressure-relief valve, factory article R900596905, for modular hydraulic stacks. This pilot-operated valve provides pressure relief along the circuit P → TA. It uses one pressure-valve cartridge within the sandwich plate.

The rotary knob adjusts pressure up to the 100 bar stage endpoint. The manufacturer article lists a maximum pressure of 315.0 bar, maximum flow of 100.0 L/min and FKM seals. The limits shown are the values listed for this factory article. Later series-level ratings do not override these article-specific values.

Tank-channel pressure must not exceed 40 bar and must also respect the valve above it in the stack. Minimum setting is flow-dependent; the pressure stage is not a factory preset. Consult the applicable March 2026 series sheet for operating-fluid conditions, pressure/flow curves, exact mounting dimensions and stack-dependent mounting screws. Screws are ordered separately. The manufacturer image is representative of the series; use the execution-specific dimensional drawing for installation.
