The Bomag 05821161 Diaphragm Valve is a genuine OEM component designed for a wide range of Bomag equipment, including BW-series single drum and tandem rollers, BC-series refuse and landfill compactors, BC-series soil compactors, MPH and RS recycler/stabilizers, BT-series tampers, and walk-behind rollers. Sourced directly from Bomag, this diaphragm valve matches the original part in material, dimensions, and performance specification. Compatible machines span models including the BW 213 D-3, BW 124 DH-4, BW 120 AD-4, BC 772 RB, BC 972 RB, BC 1172 RB, MPH 125, MPH 600, RS 650, BT 60, BT 65, BT 50, BW 6, and many more. Using part number 05821161 ensures you are installing the correct valve the first time, with no guesswork on fit or function.
Key Features
- Genuine OEM Diaphragm Integrity — manufactured to Bomag's original material and flex-rating specifications, ensuring the diaphragm seals and meters fluid flow exactly as the system was engineered to deliver
- Direct-Swap Replacement — part number 05821161 matches the original mounting interface, port sizing, and actuator geometry for a straightforward installation across all listed machines
- Broad Cross-Fleet Coverage — fits BW-series single drum rollers (including BW 213 D-3 and BW 124 DH-4), tandem rollers (including BW 120 AD-4 and BW 125 AD-4), BC-series refuse/landfill compactors, BC-series soil compactors, MPH and RS recycler/stabilizers, and BT-series tampers
- Consistent Flow Control — a properly functioning diaphragm valve maintains precise fluid regulation; a degraded or ruptured diaphragm can cause pressure loss, erratic system response, or uncontrolled fluid bypass
- Fluid-System Safety Assurance — the diaphragm provides a critical barrier between fluid chambers; an OEM-specification replacement maintains system isolation and prevents cross-contamination that could compromise hydraulic or fuel circuit integrity
A diaphragm valve uses a flexible membrane to open and close a flow passage, separating the actuating chamber from the fluid being controlled. This design allows precise regulation of liquid flow without the leak paths associated with sliding or rotating valve elements. When the diaphragm fatigues, cracks, or loses elasticity, the valve can fail to seal fully, resulting in pressure bleed-off, fluid leakage, or loss of system control — symptoms that can affect compaction output, engine fuel delivery, or hydraulic response depending on where in the machine the valve is installed. Replacing a worn diaphragm valve promptly with a correct OEM part restores the system to proper operating condition and prevents secondary damage to surrounding components.
