Feedback control
September 1st 2007

Intelligent Moog hydraulic valves are adding brain to muscle at West Midlands' based Bronx Manufacturing, which builds specialist mechanical equipment for a diverse range of industries.

The company is fitting Moog's Digital Interface Valve to a new machine that levels coiled, high strength, low carbon steel strip. It is the first application of the DIV in the UK.

The levelling machine in its fundamental state is still based on a set of rollers, but the way those rollers apply deflections to the material has improved significantly and in Bronx Manufacturing's new Completely Automatic Levelling Machine, the hydraulics are the primary flattening control element.

Depending on output, the controlling pressure of the seven hydraulic axes can be altered using the Moog DIV. Bronx has built a test rig to verify the feedback mechanism, and proved it can position to an accuracy within 5 microns.
