Water, dust, dirt particles and aggressive media often represent considerable challenges for linear actuators in process automation. Many components may not appear to have any immediate impairment of performance, but strengths and weaknesses soon become apparent in long-term operation. The new DFPI-NB3 from Festo demonstrates the performance, which a pneumatic linear actuator is capable of, even under the harshest environmental conditions.
Designed in accordance with ISO 15552 and equipped with an integrated displacement encoder and optimised piston rod guide, this innovative linear actuator delivers high performance over long periods. 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.
