The Bomag 05877201 Way Valve is a genuine OEM component designed for Bomag BW-series tandem rollers including the BW 135 AD, BW 138 AD, BW 138 AC, BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 115 AC-3, BW 115 AD-3, BW 131 AD-3, BW 131 ACW-3, BW 115 AC-5, BW 131 AD-5, and BW 131 ACW-5. Sourced directly from Bomag, this way valve is manufactured to the same standards as the original part it replaces, ensuring a correct hydraulic fit with no guesswork on compatibility. Verified against Bomag's own parts catalog, part number 05877201 is the authoritative reference for this application across the full range of BW-series tandem rollers listed above.
Key Features
- Genuine OEM Hydraulic Precision — manufactured by Bomag to exact flow-rate and pressure specifications required by the tandem roller's hydraulic circuit, not a generic substitute.
- Drop-In Hydraulic Replacement — matches original port sizing, thread pitch, and valve body dimensions for a direct installation into the existing hydraulic line without reworking fittings.
- Broad Tandem Roller Coverage — confirmed fit across BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 tandem roller variants, including AD, AC, and ACW configurations.
- Correct Flow Direction Control — restores precise hydraulic routing so drum drive and vibration systems receive fluid at the right pressure and in the correct sequence for consistent compaction performance.
- Prevents Hydraulic System Faults — a worn or failed way valve can cause erratic drum response, loss of vibration control, or unintended pressure bleed — replacing it promptly protects downstream hydraulic components.
A way valve is a directional control valve that manages which path hydraulic fluid takes within the machine's hydraulic circuit. In a tandem roller like the BW-series, it plays a key role in directing fluid to the drum drive motors, vibration system, or other hydraulic actuators depending on operator input. When a way valve begins to wear or fail internally, it can allow fluid to bypass incorrectly, causing sluggish or inconsistent drum response, loss of vibration, or unpredictable behavior under load — all of which directly affect compaction quality and machine controllability.
