The Bomag 05985311 Flow Control Valve is a genuine OEM component designed for Bomag tandem rollers across the BW 80, BW 90, BW 100, BW 120, BW 125, and BW 135 series, including generation -3, -4, and -5 variants. Sourced directly from Bomag, this valve meets the exact tolerances and flow specifications of the original part it replaces. It is confirmed to fit models including the BW 100 AD-5, BW 120 AD-5, BW 125 AC-4, BW 135 AD, and BW 80 AD-5, among others. When your tandem roller's hydraulic response becomes sluggish or erratic, replacing the flow control valve with a genuine OEM part restores consistent, calibrated performance.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original flow-rate specifications, ensuring the valve meters hydraulic fluid at the correct pressure and volume for smooth drum and drive operation
- Direct-Replacement Fitment — engineered to install in place of the original valve without modification, maintaining correct port alignment and thread specification
- Broad Tandem Roller Coverage — fits an extensive range of Bomag tandem rollers including BW 80 AD-5, BW 90 AD-5, BW 100 AC-3, BW 100 AD-4, BW 120 AD-5, BW 125 ADH, BW 135 AC, BW 120 SL-5, and BW 100 SCC-5, among others
- Restored Hydraulic Response — a worn or failed flow control valve causes uneven drum speed, erratic vibration output, or loss of drive control; this genuine replacement restores proper hydraulic regulation and operational consistency
- Verified Part Number Integrity — ordering by Bomag part number 05985311 confirms you receive the exact valve specified for your machine, eliminating guesswork on hydraulic system components where incorrect parts can cause circuit damage
A flow control valve regulates the rate at which hydraulic fluid moves through a circuit, maintaining consistent pressure and flow to the components it serves — in a tandem roller, this typically governs drum drive, vibration, or steering functions. When the valve wears or sticks, the machine may exhibit inconsistent travel speed, reduced compaction force, or loss of directional control. Replacing a faulty valve with a genuine Bomag part ensures the hydraulic system operates within its designed parameters, protecting downstream components from pressure spikes and uneven loading.
