UI Series

The widest range of pneumo-hydraulic units on the market
With the new series UI of pneumo-hydraulic units BONESI PNEUMATIK enlarges its range of hydraulic control units, developed and completely produced at its Italian headquarters, for the applications where an accurate handling of the working stroke is required.

The design features of such new series represent the summary of two applied techniques:
• The compressed air as driving power;
• The hydraulic system as control fluid.

The system offers several functions on the working strokes:
Governed and steady speeds with changing workloads and inlet air pressure;
Gradual end-stroke hydraulic cushionings to dissipate the dynamic mass energy;
Functions of quick stroke (SKIP), regulated stroke and STOP on the forward and return strokes, manageable using electric or pneumatic impulses.
