The Wacker Neuson Valve Plate is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, part is produced to the same exacting tolerances as the original, ensuring proper hydraulic sealing and flow control within the hydrostatic drive system. This valve plate is confirmed to fit across multiple machine configurations in the RD27 family, making it the correct choice when servicing either the RD27-100 or RD27-120. Sourcing the right part the first time keeps your roller operating at full hydraulic efficiency on the job.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to original tolerances for consistent hydraulic flow and pressure control within the hydrostatic drive system — no guesswork on port alignment or sealing surface geometry.
- Direct Drop-In Replacement — Matches the original mounting pattern and port configuration of the RD27 hydrostatic system, allowing straightforward installation without reworking surrounding components.
- Broad RD27 Family Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control variants, covering a wide range of machine configurations within the RD27 series.
- Sustained Compaction Performance — A properly functioning valve plate maintains correct hydraulic pressure to the drum drive, delivering consistent compaction force across asphalt and soil surfaces; a worn plate causes loss of drive responsiveness and erratic compaction output.
- Hydraulic System Integrity — As a critical sealing and metering component in the hydrostatic circuit, using a correctly rated OEM valve plate helps prevent internal hydraulic leakage that can lead to progressive system damage.
The valve plate is a precision sealing and flow-control component within the hydrostatic drive system of a vibratory roller. It sits at the interface of the hydraulic pump or motor, directing pressurized fluid through the correct ports while preventing internal bypass between the high- and low-pressure sides of the circuit. When the valve plate wears or becomes damaged, internal hydraulic leakage increases, which reduces drive force to the drum, causes sluggish or uneven machine response, and can accelerate wear throughout the hydrostatic system. Replacing a failed valve plate with a correctly matched OEM part restores proper hydraulic efficiency and drive performance.
