The Bomag 05556045 Check Valve is a genuine OEM component designed for a wide range of Bomag tandem rollers and pneumatic tyred rollers, including the BW 100, BW 120, BW 138, BW 141, BW 151, BW 154, BW 161, BW 174, BW 191, BW 202, and BW 206 series, as well as BW 80, BW 90, BW 125, BW 135, and BW 28 RH and BW 11 RH-5 pneumatic tyred roller models. Sourced directly from Bomag, this check valve matches the original part in every dimension and specification, ensuring a direct, no-fuss installation into the hydraulic system. Genuine OEM designation means this is the same component built to the same standards as the part that left the factory — no guesswork on fit or function. If you need a confirmed replacement for part number 05556045, this is the correct component for your machine.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's exact flow-control and pressure-retention tolerances for hydraulic check valve applications, not a generic substitute
- Direct Replacement Fit — matches the original port dimensions, thread specification, and seating geometry for straightforward installation in the hydraulic circuit
- Broad Tandem Roller Coverage — confirmed fit across Bomag tandem roller families including BW 80, BW 90, BW 100, BW 120, BW 125, BW 135, BW 138, BW 141, BW 151, BW 154, BW 161, BW 174, BW 191, BW 202, and BW 206 series, plus BW 11 RH-5 and BW 28 RH pneumatic tyred rollers
- Consistent One-Way Flow Control — a correctly functioning check valve maintains proper hydraulic pressure direction, preventing backflow that can cause sluggish drum response, erratic vibration, or system pressure loss
- Verified Part Number Confidence — order by part number 05556045 for an exact match with Bomag's own parts catalog, eliminating the risk of ordering a mismatched component
A check valve is a one-way flow-control device within the hydraulic system that allows fluid to pass in a single direction while blocking reverse flow. In a tandem roller, this function is critical to maintaining stable hydraulic pressure across the drum drive, vibration, and steering circuits — keeping each system operating within its designed pressure range. When a check valve wears or fails, it can allow backflow that starves actuators of pressure, leading to inconsistent drum behavior, reduced compaction force, or difficulty controlling machine movement.
