Bomag 05714749 Overflow Valve

The Bomag 05714749 Overflow Valve is a genuine OEM component designed for Bomag tandem rollers including the BW 164 AD, BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2. Sourced directly from Bomag, this overflow valve meets the original engineering specifications for the hydraulic system in these machines. As a genuine OEM part, it delivers an exact match to the component it replaces, with no guesswork on fitment or compatibility. If your tandem roller's hydraulic circuit is showing signs of pressure irregularities or fluid bypass issues, this is the correct service replacement verified by part number 05714749.

Key Features

• Genuine OEM Hydraulic Calibration — manufactured to Bomag's original pressure-relief specification, ensuring the hydraulic circuit opens and closes at precisely the correct threshold for tandem roller operation
• Direct Replacement Fit — engineered to install in the same location and connection points as the original valve, with matching port dimensions and thread spec for a straightforward swap
• Broad Tandem Roller Coverage — fits the BW 161 AC-2, BW 161 AD-2, BW 164 AD, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers
• Hydraulic System Integrity — a correctly functioning overflow valve protects the hydraulic circuit from overpressure, preventing damage to pumps, motors, and hoses; a worn or stuck valve can cause erratic drum drive behavior or system overheating
• Pressure System Safety — in a hydraulic circuit, an out-of-spec or failed overflow valve can allow dangerous pressure spikes; using the correct OEM-spec replacement maintains safe operating pressure across the system

The overflow valve is a pressure-regulating component within the machine's hydraulic circuit. Its job is to divert excess fluid back to the reservoir whenever system pressure exceeds the designed operating limit, protecting downstream components such as hydraulic motors, pumps, and control valves from damage. When this valve sticks open, the circuit loses working pressure and drum drive performance suffers; when it sticks closed or fails to relieve at the correct threshold, pressure spikes can cause hose failures or damage to expensive hydraulic components.
