The Wacker Neuson Pressure-Relief Valve is a genuine OEM component designed for the RD18, RD24, and RD27 series tandem rollers. As a direct OEM replacement sourced through the Wacker Neuson parts network, this valve is built to the exact specification required for correct hydraulic system operation across the full RD tandem roller lineup. Fitment covers a wide range of configurations including standard, C, O, US, SE, and.3 variants — making the the correct choice for a broad fleet of Wacker Neuson compaction equipment.
Key Features
- OEM-Specified Relief Pressure Rating — Manufactured to the exact cracking pressure and flow characteristics required by Wacker Neuson's hydraulic circuit design, ensuring the system operates within its intended pressure envelope.
- Direct Drop-In Hydraulic Fitting — Engineered with the correct thread type, seat geometry, and body dimensions to install directly into the existing hydraulic circuit port without modification.
- Broad RD Series Coverage — A single part number covering RD18-80, RD18-100, RD24-100, and RD27-120 tandem rollers across standard, C, O, US, SE, and .3 configuration variants.
- Protects Hydraulic Components from Overpressure Damage — A correctly functioning pressure-relief valve prevents pump, motor, and line damage caused by pressure spikes during operation; a failed valve can lead to catastrophic hydraulic system failure.
- Genuine OEM Quality Assurance — Supplied as an authentic Wacker Neuson part, validated against the original engineering drawing for the 5100011966 to confirm material grade and dimensional accuracy.
- Hydraulic System Safety Compliance — Maintaining a properly rated relief valve is critical to safe hydraulic operation; an out-of-spec valve can cause uncontrolled pressure buildup and pose a risk to operators and equipment.
A pressure-relief valve is a critical safety and control component within a hydraulic system. Its job is to open at a preset pressure threshold and divert excess fluid back to the reservoir, protecting pumps, motors, hoses, and actuators from damaging overpressure events. On a tandem roller like the RD18, RD24, or RD27 series, where hydraulic power drives both the vibratory and propulsion systems, a worn or failed pressure-relief valve can result in erratic machine behavior, overheating, or sudden hydraulic component failure — taking the machine out of service entirely.
