DFPD – the new benchmark for quarter-turn actuators. It can be used as an individual actuator or as part of a complete automated process valve system from Festo. With a torque range from 10 to 2,300 Nm, a rotation angle of up to 180° and corrosion-resistant versions, the single- or double-acting DFPD is suitable for ball valves, butterfly valves or air dampers in the chemical, pharmaceutical and beverage industries, as well as for water treatment.
The compact rack-and-pinion combination – especially in the single-acting version – is easy to install even when space is at a premium. Its range of variants, the standardised port patterns to NAMUR VDI/VDE 3845 for pilot valves as well as the many compatible peripheral devices mean that it can be operated in a large variety of applications. In addition, both the end positions can be adjusted and the direction of rotation of the single- and double-acting DFPD can be selected.
Thanks to the spring design, the pressure range can be perfectly set for the task in hand. This allows pressures from 2 to 6 bar to be easily set in increments of 0.5 bar.
The DFPD operates reliably at extreme temperatures, with the breadth of low- and high-temperature versions ranging from -50 to +150°C.
The technical highlights presented by the Product Manager
The quarter-turn actuators DFPD-C and DFPD-C-VDE2 are equipped for the harsh conditions in the chemical industry and set a new benchmark thanks to their excellent features. These include a NAMUR interface to VDI/VDE 3847, hard-anodised end caps, blow-out-proof adjusting screws for the end position, shaft centring ring and captive spring cartridges that are free of non-ferrous metals.
