Servo-Tronic System
A patented dual control mechanism that maintains roll parallelism using independent pumping groups to manage oil pressure and mass flow, backed by electro-valves for precise fine-tuning.
Technical FAQ
Ensuring the machine rolls remain parallel under unbalanced or uneven loads prevents coning or spiraling errors. The Servo-Tronic is a patented dual parallelism control system that combines independent hydraulic circuits with electronic fine-tuning valves. It maintains roll parallelism even if the electronic control system experiences a failure, allowing production to continue with consistent tolerances. This patented Davi technology is integrated across MCA, MCB, and MAV models to protect dimensional accuracy.
Unplanned equipment outages interrupt production schedules and impact a job shop's profitability. FFM is a dedicated diagnostics and predictive maintenance software module that continuously monitors component lifespans and system parameters. It displays clear alerts and warning messages on the console, allowing maintenance teams to address minor component wear before it results in costly downtime. Davi integrates FFM applications into its advanced control environments to maximize equipment uptime.

Customers benefit from 24/5 direct telephone support from specialized technicians, seamless remote diagnostics via network integration, and local spare parts inventory to guarantee operational continuity anywhere in the world.
Mechanical tilt or electronic sensor failure on standard plate rolls causes roll misalignment, leading to conical distortion, material scrap, and severe machine frame stress. The patented Davi Servo-Tronic system solves this by integrating a dual, independent hydraulic and electronic parallelism control architecture. Dedicated hydraulic pumping groups and independent fluid circuits mechanically keep the oil volume and pressure feeding each side cylinder perfectly balanced, utilizing electronic valves exclusively for micro fine-tuning. Even in the event of a total electronic control system failure, Servo-Tronic maintains exact mechanical roll parallelism hydraulically, eliminating operational downtime and protecting structural tolerances on critical parts.
Roll parallelism is managed through the patented Davi Servo-Tronic system. Servo-Tronic combines independent hydraulic and electronic control circuits. Dedicated pumping groups deliver equal oil volume and pressure to the cylinders at both ends of the roll, keeping them parallel mechanically. Fast-responding electro-valves managed by digital Roll-by-Wire architecture perform micro-adjustments. Even in the event of total electronic failure, mechanical roll parallelism is maintained hydraulically to safeguard the machine.
