Bomag 4/3-Way Valve | Part 05546455

The Bomag 05546455 4/3-Way Valve is a genuine OEM hydraulic valve designed for Bomag BW-series tandem rollers and single drum rollers. Sourced directly from Bomag, this valve delivers an exact hydraulic circuit match for models including the BW 141 AD-2, BW 174 AD, BW 202 AD-2, BW 202 AHD-2, BW 211D 3, BW 212 D-3, and BW 212 D-30, among others across the full fitment range. As an authentic Bomag component, part number 05546455 meets the same engineering standards as the original valve installed at the factory. It is the correct choice when restoring full hydraulic function to your roller after valve wear or failure.

Key Features

• Genuine OEM Hydraulic Specification — manufactured to Bomag's exact porting dimensions, pressure ratings, and flow characteristics for this valve position, ensuring the hydraulic circuit performs as originally engineered
• Direct Hydraulic Drop-In — matches the original valve's port configuration and mounting interface, allowing installation without circuit modification or line rerouting
• Broad BW-Series Coverage — fits a wide range of Bomag tandem rollers including the BW 141 AD-2, BW 151 AC-2, BW 151 AD-2, BW 161 AD-2, BW 164 AC-2, BW 170 AD, BW 174 AC, BW 174 AD, BW 180 AD, BW 184 AD, BW 202 AD-2, and BW 202 AHD-2, as well as BW 211D 3, BW 212 D-30, and additional single drum roller variants
• Restored Directional Control — a correctly functioning 4/3-way valve gives the operator precise control over hydraulic flow direction and neutral hold; a worn or stuck valve causes erratic drum drive response, loss of vibration control, or inability to hold position
• Hydraulic System Integrity — using the correct OEM valve eliminates the risk of cross-porting, pressure imbalance, or seal incompatibility that can result from incorrect valve substitution in a working hydraulic system

A 4/3-way valve is a directional control valve that routes hydraulic fluid between four ports across three switching positions — typically forward flow, reverse flow, and a neutral (blocked or open-center) hold. In a Bomag roller, this valve governs the direction and engagement of hydraulic actuators such as drum drive motors or vibration circuits, giving the operator direct command over compaction functions. When the valve wears internally or its spool sticks, the machine may lose directional response, drift unintentionally, or fail to engage vibration — making prompt replacement essential to safe, productive operation.
