The Wacker Neuson 5100013320 is a genuine OEM Nonreturn Valve designed for the RD40-130 and RD45-140 series tandem rollers, including standard, open-ROPS, canopy, DPF, and US-market configurations. As a factory-original component, the 5100013320 is manufactured to the same specification as the part it replaces, ensuring correct fitment across the full range of RD40 and RD45 variants. This valve plays a critical role in the hydraulic system of these ride-on articulated tandem rollers, and using the correct OEM part helps maintain system integrity and consistent machine performance. Confirm your model number before ordering to ensure this is the right part for your machine.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original hydraulic sealing and flow-control specification, ensuring correct cracking pressure and directional control for this valve application.
- Drop-In Hydraulic Fitment: — Engineered to match the original port sizing, thread spec, and connection type for direct installation into the hydraulic circuit of RD40-130 and RD45-140 tandem rollers.
- Broad RD Series Coverage: — A single part number covers RD40-130 and RD45-140 variants across standard, open-ROPS, canopy, DPF-equipped, and US-market configurations.
- Hydraulic System Protection: — A properly functioning nonreturn valve prevents reverse flow in the hydraulic circuit, protecting downstream components from pressure spikes and backflow-related damage.
- Verified OEM Part Number: — Part number 5100013320 is the factory-assigned reference for this component, giving you confidence you are ordering the correct replacement for your RD40 or RD45 roller.
A nonreturn valve — also known as a check valve — allows hydraulic fluid to flow freely in one direction while blocking reverse flow. In a tandem roller like the RD40-130 and RD45-140, this component helps maintain correct pressure direction within the hydraulic circuit, protecting pumps, motors, and other hydraulic components from backpressure and unintended fluid movement. When a nonreturn valve fails or begins to bypass, it can cause sluggish or inconsistent hydraulic response, pressure loss, and accelerated wear on connected components — making timely replacement essential for keeping the machine operating as intended.
