Tough on the outside, tough on the inside

Written by: Tom Austin-Morgan | Published:

Festo’s DFPI-NB3 linear actuator is claimed to be exceptionally tough, delivering high performance over long periods due to its integrated displacement encoder and optimised piston rod guide.

The DFPI-NB3 is suitable for use in the chemical and mining industries, energy producers, machine and plant builders, water treatment companies and companies handling bulk goods.

For example, its robustness and versatility especially suit this actuator for swivel motions to control ventilation, flue gas and furnace pressure control valves, hot gas valves and drum slide valves, and for regulating flow rates and filling levels. It is equally suitable for adjusting the pitch of turbine and rotor blades. In the area of linear actuated process valves, the DFPI-NB3 can also be used to optimise the motion of shut-off and dosing valves, sluice gates and pinch and dart valves.

With its integrated displacement encoder, the linear actuator DFPI-NB3 from Festo avoids increased maintenance costs, reduced component service life and re-adjustment due to wear and tear.

Upcoming models will also feature position controllers integrated into the actuator housings. The DFPI-NB3’s compact dimensions also benefit engineers as it requires little installation space.

Thanks to the standard mounting interfaces, users can draw on a range of accessories for every installation situation.
