The Wacker Neuson Pressure-Relief Valve is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100c series double drum rollers. Sourced directly from Wacker Neuson, this part matches the original specification installed at the factory — ensuring a direct, trouble-free replacement in your machine's hydraulic system. Compatible across the RD18-80, RD18-100, RD18-100c, RD18-80.3, RD18-100.3, and RD18-100c.3 model variants, part number covers the full current RD18 lineup. When it's time to restore proper hydraulic pressure control, this is the correct part for the job.
Key Features
- Genuine OEM Pressure Rating Integrity — Manufactured to Wacker Neuson's exact pressure-relief specification, ensuring the valve opens and closes at the correct hydraulic threshold — not an approximation.
- Drop-In Hydraulic Fitment — Designed to thread and seal into the same hydraulic circuit port as the original, with matching thread form and body dimensions for a straightforward installation.
- Full RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100c variants including the current .3-generation models, making this a single part number for the entire RD18 double drum roller family.
- Protects the Hydraulic System from Overpressure — A correctly functioning pressure-relief valve prevents excessive pressure spikes that can damage pumps, motors, and hoses. Replacing a worn or faulty valve restores safe, controlled hydraulic operation.
- Critical Safety Function in the Hydraulic Circuit — Pressure-relief valves are a primary safeguard against hydraulic overpressure events. Using the correct OEM part ensures the valve activates within the designed pressure range, protecting both the operator and the machine.
A pressure-relief valve is a safety and control component within the hydraulic system. Its job is to limit maximum hydraulic pressure by diverting fluid flow when pressure exceeds a set threshold — protecting downstream components like pumps, motors, and cylinders from damage caused by overpressure. On a double drum roller like the RD18 series, where the hydraulic system drives the vibration and propulsion functions, a failed or stuck pressure-relief valve can cause erratic machine behavior, loss of drive power, or in severe cases, catastrophic hydraulic component failure. Replacing a faulty valve promptly with the correct OEM part restores predictable, safe hydraulic performance.
