Key Features
- Genuine OEM Hydraulic Precision — manufactured by Bomag to exact original specifications, ensuring correct flow paths, port sizing, and pressure ratings critical for tandem roller hydraulic systems
- Direct-Fit Replacement — matches the original mounting configuration and hydraulic port layout, dropping straight into place on compatible BW-series tandem rollers
- Broad Tandem Roller Coverage — verified fitment across the BW 100, BW 120, BW 125, BW 131, BW 135, and BW 138 tandem roller families, including AC and AD drive variants
- Restored Hydraulic Control — a worn or damaged control block can cause erratic or lost hydraulic response; this genuine replacement brings full, predictable control function back to the machine
- Hydraulic System Integrity — correct valve and porting tolerances prevent internal leakage and pressure loss that can compromise drum drive and steering performance on tandem rollers
The control block is a central hydraulic valve assembly that directs and regulates pressurized fluid flow to the various hydraulic circuits on the tandem roller — including drum drive, steering, and vibration systems. It acts as a traffic controller for hydraulic power, ensuring each circuit receives the correct flow and pressure at the right time. When the control block deteriorates or fails, operators may experience sluggish response, loss of drive, or uncontrolled hydraulic behavior, making prompt replacement essential to keeping the machine working safely and effectively.
