The Wacker Neuson is a genuine OEM Check Valve designed for RD16-90 and RD16-100 tandem vibratory rollers as well as CB14B-900 and CB14B-1000 series soil and asphalt compactors. As a factory-sourced component, this Check Valve is manufactured to the exact specifications required by Wacker Neuson for these machines, ensuring proper hydraulic system function and long-term durability. Confirmed fitment spans multiple machine configurations across the RD16 and CB14B families, making part number a dependable choice for operators and service technicians working across these roller lines.
Key Features
- Genuine OEM Hydraulic Integrity — Sourced directly from Wacker Neuson, this Check Valve meets the exact flow-control and pressure-retention specs required for these roller hydraulic circuits.
- Drop-In Hydraulic Line Replacement — Engineered to match OEM port sizing and thread specifications for direct installation into the existing hydraulic circuit without rework.
- Broad RD16 and CB14B Coverage — Fits RD16-90 and RD16-100 tandem vibratory rollers as well as CB14B-900 and CB14B-1000 soil and asphalt compaction machines across multiple production builds.
- Prevents Hydraulic Backflow — A correctly functioning Check Valve maintains one-directional fluid flow, protecting pumps, motors, and actuators from pressure reversal damage that can cause costly component failures.
- Hydraulic System Safety — A failed or bypassing Check Valve can cause uncontrolled pressure spikes or loss of drive response; replacing with a verified OEM unit restores safe, predictable machine behavior.
A Check Valve is a one-way flow control component within a hydraulic circuit. Its job is to allow hydraulic fluid to pass in a single direction while blocking any reverse flow, protecting upstream components such as pumps and control valves from damaging back-pressure. In a vibratory roller or soil compactor, where hydraulic systems manage both propulsion and drum vibration, a worn or failed Check Valve can result in loss of drive force, erratic vibration output, or pressure surges that stress other hydraulic components. Replacing a faulty Check Valve promptly restores proper circuit pressure and directional control.
