Linear actuator DFPI - Integrated, sturdy, flexible! - 1

Highlights • Integrated positioner or integrated displacement encoder for external positioner • ISO 15552 for flexible installation • Easy to fit • Swivel motion possible for expanded areas of application • Sturdy and reliable • IP65, IP67, IP69K, NEMA4 The new linear actuator DFPI is equipped for a wide range of applications thanks to ISO 15552, an optionally integrated positioner or an integrated displacement encoder, and an optimised guide rod for swivel motions. It is suitable for regulating air dampers, processing bulk materials as well as for regulating flow and fill levels. Flexible installation The standardised mounting interface with comprehensive accessories to ISO 15552 means it is easy to install in a wide variety of situations. The sturdy collar nuts make it possible to mount process valves using stud bolts. The optimised piston rod guide enables swivel motions, which are necessary for regulating ventilation flaps, for example. The DFPI easily absorbs the transverse forces on the piston rod. Sturdy and reliable in use Its compact design, high IP and corrosion protection, and not least the integration of the positioner or displacement encoder make the DFPI sturdy and reliable, even in places that were previously inaccessible. All in all, the DFPI is a compact unit that is quick and easy to install.

The adjustable standards-based linear actuators DFPI-NB3P to ISO 15552 are available in two versions: the DFPI-...-E-... with a potentiometric displacement encoder which supplies an analogue voltage signal (proportional to the piston position) for an external positioner. And the DFPI-...-C1V-... with fully integrated positioner. The DFPI-...-C1V-... has a factory-set safety position in case the operating voltage or analogue setpoint fails. The position specification and feedback is provided by an analogue setpoint signal 4 ... 20 mA, while the travel speed is regulated by the integrated...
