Product Overview
The Rexroth DA 10-2-56/200-17/12 (R900563179) is a precision-engineered accumulator charging valve designed to automatically regulate the charging and discharging cycle of hydraulic bladder, diaphragm, and piston accumulators. Manufactured by Bosch Rexroth, this pressure control valve ensures optimal accumulator utilization by switching pump flow between accumulator charging and system supply based on preset pressure thresholds. The valve operates on a pilot-operated, differential pressure sensing principle, delivering reliable switching performance in high-pressure industrial hydraulic circuits. With a compact 10-size (NG10) design and robust construction, it is a direct-fit replacement for OEM installations requiring dependable accumulator management.

Engineering Features & Advantages
- Precision Pressure Control: Pilot-operated spool design delivers accurate and repeatable switching between accumulator charging and system supply, maintaining stable pressure thresholds across the full operating range.
- Automatic Charge/Discharge Logic: Integrated differential pressure sensing automatically diverts pump flow to the accumulator until the upper pressure setting is reached, then redirects flow to the system — eliminating manual intervention and reducing pump duty cycles.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with hardened spool and sleeve components, ensuring long service life and minimal leakage.
- Direct Fit Replacement: Precision-manufactured to original Rexroth specifications for direct replacement, minimising downtime and eliminating fitment issues.
