Festo has launched an intelligent linear actuator for process automation applications. The DFPI combines the functions of a linear actuator, a positioner and displacement encoder in one unit.

The DFPI solution has been designed to control knife gate valves and shut-off valves with regulated strokes and for use with all linear-actuated process valves. Festo said the DFPI is ideal for regulating knife gate valves in sewage plants, the bulk goods industry and any other applications in which the media in piping systems must be regulated.

For instance, it can be used to control sluice gates for the return sludge at final clarifiers; for the control of pump flow rate in cardboard production in the pulp and paper industry; and for the control of dart valves in many mining applications.

The DFPI has IP65, IP67 and IP69k protection and is designed to withstand harsh environments with moisture and dust, providing reliable operation. It also has high corrosion resistance class of CRC3. It is available in a wide variety of diameters (100, 125, 160, 200, 250 and 320 mm) and strokes from 40 mm up to 990 mm. Special designs above 990 mm stroke are also available on request.. www.festo.co.uk/dfpi
