The excellent control precision of the dart valves is the key to achieving optimum results in the flotation process. This ensures a constant froth level – and thus a higher yield. Festo offers three options for the automation of flotation cells in order to optimally separate fine ore and high-quality sulphide ores such as copper, copper-molybdenum and platinum group metals from the gangue.

Preconfigured from stock or individually configured? The new,

double-acting linear actuator DFPC can be both. It has been

specially designed for actuating process valves such as gate valves

or knife-gate valves, pinch valves or valve bodies without housing.

Perfect, for example, for the requirements in water and wastewater

treatment, the mining industry, power stations as well as

the paper, pulp and steel industries.

The new linear actuator DFPI is equipped for a wide range of applications thanks to ISO 15552, an optionally integrated positioner or an integrated displacement encoder, and an optimised guide rod for swivel motions.

The heavy-duty pinch valve is ideal for use with abrasive or corrosive

fl uids, pastes, pulps, powders, or media with a high solids content.

Its high performance, extremely low wear, and long service life in

open and close mode as well as in proportional control applications

make it very suitable for use in mineral processing, in the cement

and construction industry, in iron and steel production, in metallurgy

and foundries, or in aluminium production.

Automation for the requirements

in the process industry

ISO 15552, high IP and corrosion protection, an integrated displacement encoder or even a fully integrated positioner, swivel motion thanks to optimized piston rod guide – the robust and reliable linear actuator DFPI is the optimal choice for control of dampers, blades, slides, gate valves, pinch valves, dart valves, penstocks and many more.
