The Wacker Neuson is a genuine OEM Relief Valve Assembly designed for RD7 and RD11 series walk-behind tandem rollers. Sourced directly from Wacker Neuson, this part meets the same specifications as the component installed at the factory, ensuring correct hydraulic pressure regulation across compatible machine configurations. Verified fitment covers the RD7H-ES, RD7H-S, RD7-RAW, RD11A, RD11V, and RD11AEC models, including both EU and standard variants. When hydraulic system integrity is critical to compaction performance, using the correct OEM replacement is the straightforward choice.
Key Features
- Genuine OEM Hydraulic Specification — Calibrated to the exact pressure relief threshold required by the RD7 and RD11 hydraulic drive circuits, preventing over-pressurization without sacrificing drive force.
- Direct-Fit Replacement — Engineered to install into the existing hydraulic circuit mounting point with no rework to lines, fittings, or ports.
- Broad RD7 and RD11 Series Coverage — Compatible with RD7H-ES, RD7H-S, RD7-RAW, RD11A, RD11V, and RD11AEC tandem roller configurations, including EU-spec variants.
- Protects Hydraulic Components Downstream — A correctly functioning relief valve prevents pump cavitation and motor overload; a failed or incorrectly rated valve can cause progressive damage across the entire hydraulic circuit.
- Hydraulic System Safety — Proper pressure relief is critical to operator safety and machine integrity; an out-of-spec valve risks uncontrolled pressure spikes in the drive and vibration circuits.
A relief valve assembly regulates maximum hydraulic pressure within the machine's drive and vibration circuits. When hydraulic pressure rises above the designed operating threshold — due to load, temperature, or a blockage — the relief valve opens to divert fluid back to the reservoir, protecting pumps, motors, and hoses from damage. On a tandem roller like the RD7 or RD11, where both drum drive and vibratory systems depend on stable hydraulic pressure, a worn or failed relief valve can cause erratic drum speed, loss of vibratory force, or sudden pressure surges that damage downstream components. Replacing a faulty relief valve assembly promptly restores predictable hydraulic behavior and protects the broader system.
