The Bomag 05985327 Pressure Relief Valve is a genuine OEM component designed for Bomag tandem rollers across the BW 100, BW 115, BW 120, BW 125, BW 131, and BW 135 series. As a direct OEM replacement, this valve is manufactured to the same specifications as the original, ensuring proper hydraulic system pressure regulation without adaptation or modification. Compatible models include the BW 100 AC-3, BW 100 AD-3, BW 120 AC-5, BW 120 AD-5, BW 125 ADH, BW 131 AD-3, BW 135 AC, BW 135 AD, BW 120 SL-5, BW 120 SLC-5, BW 120 AD-5 CC, and many additional BW-series tandem roller variants. Ordering by part number 05985327 ensures you receive the correct valve for your machine.
Key Features
- OEM Hydraulic Precision — manufactured to original BOMAG specifications, this pressure relief valve maintains the correct system pressure thresholds that the hydraulic circuit depends on for consistent, controlled operation.
- Direct Replacement Fit — engineered to install directly into the existing hydraulic circuit of compatible BW-series tandem rollers, matching original port sizing and valve geometry for a clean swap.
- Broad Tandem Roller Coverage — fits a wide range of Bomag tandem rollers including BW 100, BW 115, BW 120, BW 125, BW 131, and BW 135 series models across multiple generation variants (-2, -3, -4, -5) in AC, AD, ACH, ADH, ACW, and SL configurations.
- Hydraulic System Integrity — a correctly functioning pressure relief valve protects pumps, motors, and actuators from pressure spikes; a failed or out-of-spec valve can cause sluggish drum response, hydraulic overheating, or component damage.
- System Protection Compliance — as a safety-critical hydraulic component, using the OEM-specified valve ensures the system relief pressure is set within design limits, protecting operators and equipment from uncontrolled pressure events.
A pressure relief valve is the hydraulic system's primary safety and control device — it opens at a set pressure to divert excess fluid back to the tank, preventing dangerous over-pressurization of pumps, motors, and lines. In Bomag tandem rollers, it plays a direct role in regulating the force delivered to the vibratory and propulsion circuits, keeping drum performance smooth and consistent across varying compaction loads. When this valve wears, sticks, or drifts from its calibrated setting, the machine may exhibit erratic drum behavior, reduced compaction output, or premature hydraulic component wear.
