The Bomag 05710011 Ventilation Valve is a genuine OEM component designed for BW 172 D-2 and BW 142 D-2 single drum rollers, as well as the BW 135 AD tandem roller. Sourced directly from Bomag, this ventilation valve carries the same specifications as the part installed at the factory, ensuring a correct, trouble-free installation. Confirmed fitment across these roller models means no guesswork when ordering — part number 05710011 is the right call when your original valve needs replacing.
Key Features
- Genuine OEM Valve Integrity — manufactured to Bomag's exact pressure and flow tolerances, ensuring proper venting performance rather than the approximations that off-spec valves can introduce
- Direct Drop-In Replacement — matches the original mounting configuration and port sizing on compatible Bomag rollers, so installation is straightforward with no rework needed
- Confirmed Roller Compatibility — fits BW 172 D-2 and BW 142 D-2 single drum rollers and the BW 135 AD tandem roller, covering multiple lines in the Bomag roller range
- Protects System Pressure Balance — a correctly functioning ventilation valve prevents pressure buildup or vacuum lock in the system it serves, keeping fluid flow and component operation within design parameters
- Fuel or Fluid System Safety — a failed or clogged ventilation valve can cause pressure imbalances that stress seals, hoses, and connected components; replacing it promptly with an OEM-spec unit helps prevent cascading failures
A ventilation valve regulates pressure within a fluid reservoir or sealed system by allowing air to move in and out as fluid levels change during operation. Without proper venting, negative pressure can restrict fluid draw and starve downstream components, while excess positive pressure can force fluid past seals and cause leaks. When this valve becomes clogged, stuck closed, or fails to seat correctly, the resulting pressure imbalance can damage seals and reduce the efficiency of the system it supports — making timely replacement with a quality OEM part essential to keeping your roller running as intended.
