The Bomag 05542556 Check Valve is a genuine OEM component designed for a broad range of Bomag tandem rollers, pneumatic tyred rollers, recycler/stabilizers, and cold milling machines. This check valve delivers an exact OEM fit across the BW-series tandem roller lineup — including the BW 80 AD-5, BW 90 AD-5, BW 100 AD-5, BW 120 AD-5, BW 135 AD-5, BW 138 AD-5, BW 90 AC-5, BW 100 AC-5, BW 120 AC-5, BW 138 AC-5, BW 90 SC-5, BW 100 SC-5, BW 90 SL-5, BW 90 SL-5 CC, BW 100 SLM-5, BW 100 SCC-5, BW 100 ADM-5, BW 100 ACM-5, and BW 120 SL-5 tandem rollers — as well as the BW 12 R pneumatic tyred roller, RS 500 and RS 460 recycler/stabilizers, and BM2000/65 Stage V and BM2200/65 Stage V cold milling machines. Sourced directly from Bomag, this part meets the same production standards as the valve installed at the factory, ensuring proper hydraulic circuit function and long service life.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured by Bomag to the exact flow-control and pressure-rating specifications required for these hydraulic systems, with no guesswork on sealing performance or cracking pressure
- Direct-Swap Installation — matches the original port dimensions and mounting configuration, dropping straight into place without rework or adapter fittings
- Wide Equipment Coverage — fits BW-series tandem rollers from the BW 80 AD-5 through the BW 138 AD-5 and BW 138 AC-5, plus the BW 12 R pneumatic tyred roller, RS 500 and RS 460 recycler/stabilizers, and BM2000/65 Stage V and BM2200/65 Stage V cold milling machines
- Protects Hydraulic Circuit Operation — a correctly functioning check valve prevents reverse flow and pressure loss that can cause erratic drum drive, steering sluggishness, or uncontrolled movement on grade
- Verified by Part Number 05542556 — cross-reference this number against your machine's service manual or parts diagram before ordering to confirm the correct application
A check valve is a one-way flow control device within the hydraulic system that allows fluid to move freely in one direction while blocking reverse flow. On compaction equipment and milling machines, check valves are critical for maintaining consistent pressure in drive circuits, brake systems, and auxiliary hydraulics — keeping each circuit isolated so pressure drops in one loop do not bleed into another. When a check valve fails or begins to leak internally, symptoms typically include loss of drive power, brake drift, or unstable hydraulic response, any of which can compromise both machine productivity and operator safety.
