The Wacker Neuson Pressure-Relief Valve is a genuine OEM component designed for RD18-80, RD18-100, and RD18-100c series double drum rollers. Sourced directly from Wacker Neuson, this part carries the same OEM specification as the original, so you get a fit and function that matches what came off the assembly line. Compatibility spans the full RD18 series lineup, including the RD18-80, RD18-80.3, RD18-100, RD18-100.3, RD18-100c, and RD18-100c.3 models, making the correct choice across the range.
Key Features
- Calibrated Relief Pressure Rating — Genuine OEM construction ensures the valve opens at the correct system pressure threshold, protecting hydraulic circuits from over-pressurization without unnecessary flow loss.
- Direct Drop-In Replacement — Engineered to the original port dimensions and thread specification, this valve installs directly into the existing hydraulic circuit without rework or adaptation.
- Broad RD18 Series Coverage — A single part number covers RD18-80, RD18-80.3, RD18-100, RD18-100.3, RD18-100c, and RD18-100c.3 rollers, simplifying parts ordering across your fleet.
- Hydraulic System Protection — A correctly functioning pressure-relief valve prevents costly pump and motor damage by diverting excess flow before pressure spikes can cause component failure.
- Safety-Critical Hydraulic Control — Pressure-relief valves are a key safeguard in hydraulic systems; using a genuine OEM replacement maintains the designed pressure limits and operational safety margins of the machine.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized Wacker Neuson replacement, backed by the manufacturer's own part number 5100068733 for verified accuracy.
A pressure-relief valve is a safety and control component within a hydraulic system. Its job is to limit the maximum pressure in the circuit by opening and diverting oil flow back to the tank whenever pressure exceeds the set limit — acting as a pressure ceiling that protects pumps, motors, hoses, and other hydraulic components from damage. On a double drum roller like the RD18 series, where hydraulic drive and vibration systems operate under sustained load, a worn or stuck pressure-relief valve can either allow dangerous over-pressure spikes that damage expensive components or bleed off pressure prematurely, causing sluggish drive performance and loss of compaction force.
