The Bomag 05878121 3/2-Way Valve is a genuine OEM component designed for a wide range of Bomag BW-series tandem rollers and single drum rollers, including the BW 184 AD, BW 213 DH-3, BW 225 D-3, BW 174 AD-2, BW 151 AD-2, and BW 124 DH-3, among many others. Sourced directly from Bomag, this valve delivers an exact OEM specification fit for the hydraulic systems it serves. Whether you are servicing a BW 177 D-3 single drum roller or a BW 154 AD-2 tandem roller, this part matches the original component your machine was built with. Confirm your model against the full fitment list to ensure compatibility before ordering.
Key Features
- Genuine OEM Valve Construction — manufactured to Bomag's original hydraulic flow and switching specifications, ensuring correct pressure response and directional control performance for this valve type
- Direct OEM Replacement — engineered to install in place of the original 3/2-way valve using existing ports and mounting points, with no adaptation needed to the hydraulic circuit
- Broad Bomag Roller Coverage — fits an extensive range of BW-series tandem rollers and single drum rollers, including the BW 184 AD, BW 213 PDH-3, BW 216 DH-3, BW 219 DH-3, BW 174 AC-2, BW 151 AC-4, BW 203 AD-4 AM, BW 124 PDH-3, and C 815 C, among others
- Hydraulic System Integrity — a properly functioning 3/2-way valve maintains correct flow switching in the hydraulic circuit; a failed or worn valve can cause loss of directional control, erratic system behavior, or pressure faults that affect compaction performance
- Operational Safety in Hydraulic Circuits — correct valve function is critical to maintaining predictable hydraulic response; using an OEM-spec replacement supports safe, controlled machine operation
A 3/2-way valve is a directional control valve with three ports and two switching positions. In a roller's hydraulic system, it routes pressurized fluid along one of two paths depending on its current state, enabling or cutting off flow to a specific circuit or actuator. When this valve sticks, leaks internally, or fails to switch cleanly, the hydraulic function it controls — whether that is engaging a drive circuit, a vibration system, or an auxiliary function — becomes unreliable or inoperative, making prompt replacement essential to restore full machine performance.
