The Wacker Neuson is a genuine OEM RD16 Pump Sequence Valve designed for RD16-90 and RD16-100 series tandem vibratory rollers, as well as CB14B-900 and CB14B-1000 series machines used in soil and asphalt compaction. As a factory-sourced component, part is manufactured to the exact hydraulic specifications required for proper pump circuit operation in these machines. Correct sequencing pressure is critical to consistent drum drive performance and safe machine operation on the job. Sourcing this part directly from Wacker Neuson ensures you are installing the correct valve without risk of hydraulic mismatch.
Key Features
- Genuine OEM Hydraulic Specification: — Manufactured to the precise pressure-sequencing tolerance required by the RD16 pump circuit — not a generic valve adapted for the application.
- Drop-In Hydraulic Fit: — Engineered to install directly into the existing pump assembly port with correct thread form and seat geometry for the RD16 series.
- Broad RD16 and CB14B Fitment: — Confirmed for RD16-90 and RD16-100 tandem rollers across multiple build configurations, plus CB14B-900 and CB14B-1000 soil and asphalt compactors.
- Protects Drum Drive Consistency: — A correctly functioning sequence valve maintains the hydraulic priority order that keeps both drums operating at the right pressure — a worn or stuck valve can cause uneven drum response or loss of drive.
- Hydraulic System Integrity: — In a high-pressure pump circuit, an incorrect or failing sequence valve risks pressure spikes and uncontrolled flow events; using the verified OEM part keeps the circuit operating within its designed pressure envelope.
A sequence valve in a hydraulic pump circuit controls the order and pressure threshold at which hydraulic flow is directed to downstream functions — in this case, managing the drive circuit pressure for the compaction drums on RD16 and CB14B series tandem rollers. When the valve is functioning correctly, the hydraulic system operates in the intended pressure sequence, delivering consistent and controllable drum force across the full compaction pass. When the valve wears, sticks, or fails, operators may notice erratic drum behavior, loss of drive to one or both drums, or abnormal pressure readings — all of which affect compaction quality and can place added stress on other hydraulic components.
