The Wacker Neuson Back Pressure Valve is a genuine OEM component designed for the DPU 9070 and DPU 100-70 reversible vibratory plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the exact specification required for correct hydraulic system operation in these heavy-duty diesel reversible plates. This part ships with verified fitment against both the DPU 9070 and the DPU 100-70, giving you confidence before the wrench comes out.
Key Features
- Genuine OEM Hydraulic Specification: — Engineered to maintain the precise cracking pressure required by the DPU series hydraulic exciter circuit — not a generic valve that approximates the spec.
- Drop-In Hydraulic Port Fit: — Matches the OEM thread form and port sizing of the DPU 9070 and DPU 100-70, so installation seats correctly without rework or adapter fittings.
- Confirmed Fitment — DPU 9070 and DPU 100-70: — Verified against Wacker Neuson parts records for both the DPU 9070 and the 100 kN, 70 cm/28 in DPU 100-70 reversible vibratory plate compactors.
- Directional Control Integrity: — A correctly functioning back pressure valve maintains consistent hydraulic resistance in the exciter circuit, enabling smooth, controlled plate reversal under load on soil and aggregate.
- Hydraulic System Safety: — A failed or bypassing back pressure valve can allow uncontrolled flow in the exciter circuit, resulting in erratic reversal behavior and potential operator hazard on site — correct specification matters here.
The back pressure valve regulates hydraulic flow within the exciter system of a reversible vibratory plate compactor, maintaining a set resistance that allows the operator to control the direction of plate travel. By holding pressure on the return side of the hydraulic circuit, it ensures the eccentric weights shift smoothly and predictably when the operator commands a direction change. When this valve wears, sticks, or fails, the plate may refuse to reverse, reverse erratically, or lose compaction force — all signs that the valve needs to be replaced promptly to restore full machine performance.
