As a direct OEM replacement, it is manufactured to the exact specifications of the original part, ensuring a correct, hassle-free installation into your machine's hydraulic circuit. This assembly is the right choice when you need confidence in both fit and function on a working machine. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Spec Pressure Rating — Manufactured to the original relief pressure setting, so the hydraulic system operates within its designed pressure range from day one.

- Genuine Wacker Neuson Part — Supplied as an authorized OEM assembly under part number 5100032945, sourced directly through the Wacker Neuson parts network.
- Assembly Included — Supplied as a complete assembly rather than individual components, simplifying the service process and reducing bench time.
A relief valve assembly regulates hydraulic pressure within a machine's circuit by diverting excess fluid back to the reservoir when pressure exceeds the system's designed limit. This protects pumps, actuators, and hoses from damaging over-pressure conditions during heavy lifting, digging, or loader operation. When a relief valve wears or fails, the machine may exhibit sluggish hydraulic response, uncontrolled pressure spikes, or overheating — all signs that the assembly needs to be inspected and replaced promptly.
