The Wacker Neuson is a genuine OEM Relief Valve designed for the RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 series remote-controlled vibratory trench rollers. As a factory-sourced component, it is manufactured to the exact specifications required by the hydraulic system in these machines, ensuring correct pressure regulation from day one. This part covers an extensive range of RT-series configurations, including EU-spec and smooth-drum variants across multiple machine numbers. If you are servicing an RT56 or RT82 trench roller and need a hydraulic relief valve you can trust, the is the verified OEM solution.
Key Features
- OEM-Spec Pressure Rating — Manufactured to Wacker Neuson's exact cracking-pressure specification, so the hydraulic circuit opens and bypasses at the correct threshold — no calibration guesswork.
- Direct Hydraulic System Fit — Engineered to drop into the existing hydraulic circuit of RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 trench rollers using the original port connections and thread form.
- Broad RT-Series Coverage — Confirmed fitment across RT56 and RT82 platform variants, including SC and SC2 generations, EU-spec machines, and smooth-drum configurations.
- Protects Hydraulic Components — A properly functioning relief valve prevents over-pressurization in the hydraulic system, protecting pumps, motors, and hoses from damage caused by pressure spikes.
- Genuine OEM Sourcing — Supplied as a Wacker Neuson genuine OEM part, meaning the valve body, seat, and spring are built and tested to the same standard as the original component installed at the factory.
A hydraulic relief valve acts as a pressure safety regulator within the machine's hydraulic circuit. When system pressure exceeds its set limit — due to load spikes or a stalled actuator — the valve opens to divert fluid back to the tank, capping pressure at a safe level. On remote-controlled trench rollers like the RT56-SC and RT82-SC series, this function is critical: without it, hydraulic pumps, drive motors, and hoses are exposed to damaging over-pressure events. A worn or stuck relief valve can cause sluggish drive response, excessive heat buildup, or catastrophic hydraulic component failure, making timely replacement essential to keeping the roller operating as intended.
