The Bomag 05802255 Flush Charge Pressure Valve is a genuine OEM component designed for Bomag single drum rollers and tandem rollers across multiple series, including the BW 124, BW 151, BW 226, BW 141, BW 154, BW 170, and C 815 C. Sourced directly from Bomag, this valve meets the exact engineering standards of the original part. It installs as a direct replacement in the hydraulic drive circuit, ensuring the flush and charge pressure system operates within the parameters the machine was built around. Compatible fitment spans both -4 and -5 generation models, including AM and articulated variants.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original pressure-regulation specifications, ensuring the flush charge circuit opens and closes at the correct set point for the hydraulic drive system
- Direct Drop-In Replacement — engineered to the same port size, thread pitch, and cracking pressure as the original, so this valve seats correctly without modification
- Broad Roller Coverage — fits a wide range of Bomag single drum rollers and tandem rollers, including BW 124 DH-3, BW 124 DH-5, BW 226 DH-4, BW 226 DH-5, BW 151 AD-4, BW 151 AD-5, BW 141 AD-4, BW 141 AD-5, BW 154 AD-4 AM, BW 170 AD-2 AM, and C 815 C, among others
- Protects Hydrostatic Drive Integrity — a correctly functioning flush charge pressure valve removes excess heat and contaminated oil from the closed hydraulic loop; a failed or stuck valve leads to overheating, accelerated component wear, and loss of drive performance
- Verified Part Number Traceability — part number 05802255 matches Bomag's OEM catalog, giving you confidence that you are ordering the correct valve for your machine configuration
The flush charge pressure valve is a critical component in the closed-loop hydrostatic drive system used in Bomag rollers. Its job is to regulate the pressure at which a small volume of hydraulic fluid is continuously flushed from the low-pressure side of the drive loop, carrying heat and fine contaminants away before fresh, filtered charge fluid replaces it. This flushing action keeps hydraulic temperatures in check and protects the pump, motor, and other drive components from heat-related degradation. When this valve fails — whether it sticks open, sticks closed, or loses its calibrated cracking pressure — the drive circuit can overheat, efficiency drops, and costly pump or motor damage can follow quickly.
