The Wacker Neuson Pressure Relief Valve is a genuine OEM component designed for the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series tandem rollers, including standard, canopy, open-ROPS, and DPF-equipped variants. As a direct OEM replacement, this valve is manufactured to the same specification as the original part, ensuring correct cracking pressure and proper hydraulic system behavior straight out of the box. Compatibility spans a wide range of Wacker Neuson tandem roller configurations, making part number a go-to solution for fleet operators managing multiple roller models. Confirm your machine's serial number against the fitment list before ordering to ensure the right match for your unit.
Key Features
- Correct Cracking Pressure Rating — Manufactured to OEM-specified pressure thresholds, so the valve opens and closes at exactly the right point in the hydraulic circuit.
- Drop-In Hydraulic Fitment — Designed to thread directly into the existing hydraulic circuit port with no rework or adapter fittings needed.
- Broad Series Coverage — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, canopy, open-ROPS, and DPF configurations.
- Hydraulic System Integrity — A properly functioning pressure relief valve prevents overpressure events that can damage pumps, motors, and hoses — protecting the entire hydraulic circuit.
- Overpressure Safety Protection — In hydraulic systems, a failed or stuck relief valve can cause dangerous pressure spikes; this genuine OEM part restores the circuit's designed pressure limit and keeps operation within safe parameters.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the full OEM part number 5100012114 for confident identification and reordering.
A pressure relief valve is a critical safety and control component in the hydraulic system of a tandem roller. Its job is to limit maximum system pressure by diverting hydraulic fluid back to the reservoir when pressure exceeds a preset level, protecting pumps, motors, cylinders, and hoses from damage caused by overpressure. When this valve wears out, sticks open, or fails to seat correctly, the machine may exhibit weak drive performance, excessive heat buildup in the hydraulic fluid, or uncontrolled pressure surges that can cause premature failure of other hydraulic components.
