The Wacker Neuson Relief Valve is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem ride-on rollers. Sourced directly from Wacker Neuson, this part is manufactured to the same specifications as the original, ensuring a correct, drop-in replacement for the hydraulic system it serves. Compatible across multiple build variants of the RD27 Pro, RD27 Basic, and RD27 T4F series, part number covers a broad range of machines in the RD27 lineup. When your roller's hydraulic circuit needs a relief valve replacement, this is the part built to restore proper system function.
Key Features
- OEM-Spec Pressure Rating — Manufactured to the original pressure relief threshold, ensuring the hydraulic circuit opens and closes at the correct system pressure — not an approximation.
- Direct Hydraulic System Fit — Engineered to match the original port sizing and thread specification of the RD27 hydraulic circuit for a straightforward swap without adaptation.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 variants across Hydrostatic Vibratory Roller, Ride-On Roller, RD27 Pro Tandem, RD27 Basic T4F, and RD27 Pro T4F builds.
- Protects Hydraulic Components — A correctly functioning relief valve prevents dangerous pressure spikes that can damage pumps, motors, hoses, and seals throughout the hydrostatic drive system.
- Genuine Wacker Neuson Part — Supplied as authentic OEM stock under part number 5100016592, backed by Wacker Neuson's parts program for traceability and quality assurance.
- Pressure System Safety — Relief valves are a critical safety component in hydraulic circuits; using a correctly rated OEM part helps maintain safe operating pressures and protects the operator and machine.
A relief valve regulates hydraulic system pressure by opening a controlled bypass path when pressure exceeds a set limit, redirecting fluid back to the reservoir rather than allowing the circuit to over-pressurize. In a hydrostatic roller like the RD27 series, this valve is essential to protecting the drive system — without it functioning correctly, excessive pressure can burst hoses, damage the hydrostatic pump or motor, and create unsafe operating conditions. A worn or stuck relief valve typically shows up as loss of drive power, overheating hydraulic fluid, or erratic machine behavior under load.
