The Wacker Neuson Valve is a genuine OEM Valve designed for the RD18-80, RD18-100, and RD18-100C series tandem rollers. Sourced directly from Wacker Neuson, this is the same part installed at the factory, ensuring correct fit and function across the full RD18 roller lineup — including US and SE variants. Whether you're servicing an RD18-80.3, RD18-100.3, or RD18-100C.3, part number covers the range. Keeping the hydraulic circuit operating correctly depends on valves that meet exact OEM specifications, and this replacement delivers precisely that.
Key Features
- OEM-Spec Flow Control: — Manufactured to Wacker Neuson's exact pressure and flow tolerances, ensuring the valve opens and closes at the correct thresholds for consistent compaction performance.
- Drop-In Installation: — Matches the original valve's port sizing and thread specification, connecting directly to existing hydraulic lines without rework or adaptation.
- Broad RD18 Series Coverage: — Fits RD18-80, RD18-100, and RD18-100C tandem rollers across standard, US, SE, and .3 sub-variants, making it the go-to replacement for the entire RD18 family.
- Compaction Output Protection: — A correctly functioning valve maintains proper hydraulic pressure distribution to the drums; a worn or stuck valve can cause uneven compaction, loss of vibration, or erratic drive response.
- Genuine Wacker Neuson Part: — Supplied as authentic OEM stock, so you're fitting the same component Wacker Neuson specifies for factory repair and dealer service work.
A valve in a tandem roller's hydraulic system regulates the flow and pressure of hydraulic fluid between key circuits — controlling functions such as drum vibration, propulsion, and steering response. When a valve sticks, leaks internally, or fails to seat correctly, the machine may lose vibration force, respond sluggishly, or develop uncontrolled pressure buildup that stresses other hydraulic components. Replacing a faulty valve promptly with a correctly rated OEM part restores full hydraulic control and protects the integrity of the wider system.
