The Wacker Neuson Valve is a genuine OEM component designed for the RD7H-S tandem roller series and the DPU 4045H, DPU 5045H, and DPU 5545H families of diesel reversible vibratory plate compactors. As a direct OEM replacement, this valve is manufactured to the same specifications as the original, ensuring correct operation within the hydraulic or fuel system it serves. Fitment spans a wide range of DPU variants — including standard, ap, eh, ec, and US-spec configurations — as well as RD7Heh, RD7Hehf, and RD7Hehfb tandem roller models. Always verify your machine's model number before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this valve meets the original flow-rate and pressure tolerances required by the hydraulic or fuel circuit it controls.
- Drop-In Replacement — Matches the original port sizing and mounting interface, allowing straightforward installation without system modifications.
- Broad Model Coverage — Fits the DPU 4045H, DPU 5045H, and DPU 5545H reversible plate compactor families, plus RD7H-S and RD7Heh-series tandem rollers, covering standard, EU, US, ap, eh, ec, and combination variants.
- Maintains System Pressure Integrity — A correctly functioning valve preserves the pressure balance in the hydraulic or fuel circuit; a worn or stuck valve can cause erratic machine response, loss of drive force, or failure to start.
- Fuel and Hydraulic System Safety — Valve integrity is critical in diesel-powered equipment; a failed valve can result in uncontrolled fluid flow, posing a fire or operational hazard on the worksite.
A valve in this application regulates the flow or pressure of fluid — whether hydraulic oil or diesel fuel — within a specific circuit of the machine. By opening, closing, or modulating flow at the correct moment, it allows the machine's drive, compaction, or fuel delivery system to respond accurately to operator inputs. When a valve sticks, leaks, or fails to seat properly, the affected system loses control over fluid movement, which can manifest as loss of propulsion, inconsistent compaction force, hard starting, or stalling. Replacing a faulty valve with a correct OEM part restores precise fluid control and returns the machine to proper working condition.
