The Wacker Neuson Check Valve is a genuine OEM component designed for the RD16-90, RD16-100, and CB14B series tandem rollers. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a proper fit within the hydraulic system of your machine. This check valve is confirmed compatible across multiple machine numbers within the RD16-90, RD16-100, and CB14B-900 and CB14B-1000 series, covering both standard and hydrostatic configurations. Ordering by part number ensures you receive the correct valve for your specific roller configuration.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the exact cracking pressure and flow tolerances required for the hydrostatic drive circuits on Wacker Neuson tandem rollers, ensuring the valve opens and seats correctly under operating conditions.
- Direct Drop-In Fit — Matches the original port threading, body dimensions, and sealing interface, allowing straightforward installation without modification to existing hydraulic lines or manifold ports.
- Broad Series Compatibility — Verified fitment across RD16-90, RD16-100, CB14B-900, and CB14B-1000 tandem rollers, including standard vibratory and hydrostatic (IRH) machine configurations used in soil and asphalt compaction.
- Protects Hydraulic Circuit Efficiency — A correctly functioning check valve prevents backflow in the hydraulic system, maintaining consistent drum drive pressure and smooth directional control during compaction passes.
- Hydraulic System Safety — A failed or leaking check valve can allow unintended fluid backflow, leading to loss of drive response or uncontrolled machine behavior on grade — replacing it promptly keeps the hydraulic circuit operating as engineered.
A check valve is a one-way flow control component within the hydraulic circuit of a tandem roller. Its job is to allow hydraulic fluid to flow freely in one direction while blocking reverse flow, which protects downstream components such as pumps, motors, and control valves from pressure spikes and backflow events. On a vibratory tandem roller like the RD16 and CB14B series, where the hydrostatic drive system manages both propulsion and drum vibration, a worn or stuck check valve can cause sluggish drive response, pressure loss, or erratic machine behavior — making timely replacement essential to keeping your compaction work on schedule.
