Festo's Positioning Linear Drive DFPI is designed for linear actuated process valves
Festo introduces the DFPI modulating drive for all linear actuated process valves. Its all-in-one design and technology make it well suited for controlling knife gate valves and shut-off valves with varying strokes. The DFPI features an integrated displacement encoder via lineary potentiometric displacement sensor, valve manifold, positioner and a sturdy electrical connection. Fow control functions, the back-and-forth movement speed of the piston rod, can be set separately or independently of each other; intermediate positions sensing is optional.
