Bosch Rexroth R900704216 – OEM Hydraulic Valve (Material Number) for Reliable Motion & Pressure Control

The Bosch Rexroth material number R900704216 refers to an original Rexroth hydraulic valve/valve assembly used in industrial power units, presses, machine tools, and mobile equipment. From my experience, customers use this exact material number when they need a drop‑in replacement that preserves the installed manifold pattern, flow behavior, and pressure capability—without reworking the hydraulic block or re-qualifying the machine. One thing I appreciate is the consistent Rexroth traceability; it makes maintenance cycles and audits much cleaner in many cases.

Order Placement Process and Guarantees

Key Features

• Genuine Bosch Rexroth material – Ensures correct fit and function versus the installed manifold/block without re-engineering.
• Factory-tested performance – Typically pressure and leakage are verified to Rexroth standards before dispatch.
• ISO pattern compatibility – In most cases these valves use standard ISO 4401 (CETOP) interfaces for straightforward swap-outs.
• Service-friendly design – You might notice that seals, coils (if fitted), and connectors are easy to access for quick maintenance.
• Stable operation – Rexroth’s machining and spool guidance typically deliver low hysteresis and consistent switching.
• Traceability – Material number/ID gives clear lineage for audits and PM programs.

Technical Specifications

Related or Supporting Products

• Bosch Rexroth 4WE6 series (CETOP 3) – Directional spool valves; compact footprint for flows up to approx. 60 L/min depending on spool.
• Bosch Rexroth 4WE10 series (CETOP 5) – Larger frame for higher flow; used when pressure drop needs to be reduced.
• Rexroth Z2S sandwich check valves – Often stacked under directional valves to prevent backflow in actuators.
• Coils and connectors (e.g., EG24, DIN connectors) – 24 VDC/12 VDC options; angled or straight connectors with LED/suppressor choices.
• ISO 4401 subplates – NG6/NG10 subplates with G, NPT, or SAE ports to suit existing piping standards.

If you’re replacing an existing unit, sending a photo of the nameplate or the full type code next to R900704216 helps us match coils, seals, and spool type perfectly.

Installation & Maintenance

• Environment & mounting – Install on a clean ISO 4401 subplate; ensure flatness and correct O-ring grooves. Provide enough clearance for coil/connector service (if fitted).
• Hydraulic cleanliness – Flush lines. Maintain recommended filtration and cleanliness class to avoid spool sticking and premature wear.
• Wiring – Match coil voltage and connector pinout; add surge suppression where appropriate. You might notice that miswired coils heat up quickly—check polarity on DC.
• Torque & sealing – Use specified bolt torque in a cross pattern; replace O-rings during service. NBR is typical; FKM is chosen for higher temperatures or alternative fluids.
• Routine checks – Inspect for leakage, connector integrity, oil temperature, and unusual switching noise. Functional tests after filter changes are a good practice.
• Calibration/setting – For pressure or proportional variants, verify set-points after installation and lock adjustments.

A quick customer note: one maintenance team mentioned that simply renewing the connector and O-rings with the valve swap eliminated intermittent faults they had chased for months. Small parts make a big difference, typically.
