The Bomag 05574281 Overflow Valve is a genuine OEM component designed for Bomag BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC pneumatic tyred rollers, and the BW177PDH 5 single drum roller. Sourced directly from Bomag, this valve carries the same part number, materials, and dimensional tolerances as the component installed on the production line. This overflow valve delivers an exact hydraulic fit, ensuring the system operates within its designed pressure parameters without adaptation or modification. If your machine is showing signs of hydraulic pressure irregularities, replacing the overflow valve with part number 05574281 is the correct service action.
Key Features
- OEM Hydraulic Precision — Manufactured to Bomag's exact pressure-relief tolerances, ensuring the valve opens and closes at the correct threshold for your machine's hydraulic circuit.
- Direct-Fit Replacement — Matches the original port size, thread spec, and valve geometry for a straightforward swap into the existing hydraulic line.
- Broad Bomag Coverage — Fits BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, and BW 27 RH-4i BC pneumatic tyred rollers, as well as the BW177PDH 5 single drum roller.
- Hydraulic System Protection — A correctly functioning overflow valve prevents excess pressure from damaging pumps, motors, and lines — a failed or stuck valve can cause costly system-wide hydraulic damage.
- Genuine OEM Confidence — Backed by Bomag's OEM supply chain, part number 05574281 is the same component used in original equipment assembly — not a substitute or approximation.
An overflow valve — also known as a pressure relief valve — regulates hydraulic pressure within a circuit by diverting excess fluid back to the reservoir when system pressure exceeds a set limit. This prevents pressure spikes from damaging sensitive downstream components such as hydraulic motors, cylinders, and control valves. When an overflow valve fails — whether it sticks open, sticks closed, or no longer holds its rated cracking pressure — the machine may exhibit sluggish hydraulic response, overheating, or uncontrolled pressure buildup, all of which can lead to component failure and unplanned downtime.
