Electropneumatic Positioning Of Linear Gate Valve - DFPI DatasheetSource: Festo Corporation
Its all-in-one design and patented technology make it ideal for controlling knife gate valves and shut-off valves with varying strokes: integrated displacement encoder via lineary potentiometric displacement sensor, valve manifold, ositioner and an extremely sturdy electrical connection.
A sturdy and compact housing, protection in IP65, IP67 and IP69k and high corrosion resistance KBK3: ideal properties for exterior use.
Thanks to self-initialization, commissioning is just as quick and easy as integration in an existing control architecture with a setpoint signal of 4 ... 20 mA.
Fow control functions, the backand- forth movement speed of the piston rod, can be set separately or independently of each other; intermediate positions sensing is optional.
