The Wacker Neuson is a genuine OEM Check Valve designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem rollers. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory, ensuring a correct, like-for-like replacement. Confirmed fitment spans a wide range of RD27 configurations, including RD27 Pro Tandem Roller and RD27 Ride-On Roller variants. Keep your roller operating at full hydraulic efficiency by replacing a worn or failing check valve with the correct OEM part.
Key Features
- OEM Hydraulic Precision — Manufactured to Wacker Neuson's exact flow and pressure specifications, ensuring the valve opens and seats correctly under operating conditions.
- Direct-Fit Replacement — Engineered to match the original mounting interface and port dimensions on RD27 series rollers, dropping straight into the existing hydraulic circuit.
- Broad RD27 Series Compatibility — Fits RD27-100 and RD27-120 models across multiple build variants, including Hydrostatic Vibratory Roller, Ride-On Roller, and RD27 Pro Tandem Roller configurations.
- Maintains Hydraulic System Integrity — A correctly functioning check valve prevents backflow in the hydrostatic circuit, protecting pumps, motors, and other downstream components from pressure surges.
- Genuine Wacker Neuson Part — Part number 5200016804 is an authorized OEM component, giving you confidence that material grade and internal tolerances match the original design intent.
A check valve is a one-way flow control component within the hydraulic circuit that allows fluid to pass in a single direction while blocking reverse flow. On hydrostatic vibratory rollers like the RD27 series, it plays a critical role in maintaining stable pressure and protecting sensitive hydraulic components from damaging backpressure. When a check valve begins to fail — through seat wear, spring fatigue, or contamination — it can cause erratic machine response, pressure loss, or accelerated wear on pumps and drive motors.
