The Bomag 05546726 4/3-Way Valve is a genuine OEM hydraulic control component designed for Bomag BW 170, BW 174, and BW 184 series tandem rollers. As a direct OEM replacement, this valve is manufactured to the same specifications as the original, ensuring correct hydraulic response and system integrity across every compatible machine. This valve fits a broad range of tandem roller variants, including the BW 170 AD, BW 170 AD-2 AM, BW 174 AC, BW 174 AC-2, BW 174 AD, BW 174 AD-2, BW 174 AP, BW 174 ACP, BW 184 AD, and BW 184 AD-2, among others. Sourced directly from Bomag, part number 05546726 is the correct, catalog-verified component for these machines.
Key Features
- OEM Hydraulic Precision — manufactured to Bomag's original flow and pressure specifications, ensuring accurate directional control of hydraulic circuits on tandem rollers
- Drop-In Hydraulic Replacement — mates to existing hydraulic ports and mounting points without rework, preserving original system layout and connection integrity
- Broad Tandem Roller Coverage — fits BW 170, BW 174, and BW 184 tandem roller variants, including AC, AD, AP, ACP, and AM configurations across multiple model generations
- Consistent Directional Control — a properly functioning 4/3-way valve maintains precise hydraulic flow switching across all three positions; a worn or failed valve causes sluggish, erratic, or lost directional response in the machine's hydraulic system
- Hydraulic System Safety — correct valve operation is critical to maintaining controlled drum drive and steering response; using the verified OEM component reduces the risk of uncontrolled hydraulic behavior during compaction operations
A 4/3-way valve is a directional control valve with four hydraulic ports and three operating positions — typically flow in one direction, flow reversed, and a neutral (blocked or open) center position. On Bomag tandem rollers, this valve governs the routing of hydraulic fluid to drive or actuate key systems, allowing the operator to precisely control direction and function. When the valve wears, sticks, or fails internally, the machine may lose smooth directional control, respond slowly to inputs, or fail to hold position — making prompt replacement essential to safe and productive operation.
