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 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 standardized hole 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 stop 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 … +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-anodized end caps, blow-out-proof adjusting screws for the end position, shaft centering ring and captive spring cartridges that are free of non-ferrous metals.
The configurator for process valve units makes selecting the optimum solution child's play. After you select your parameters, the configurator immediately suggests appropriate combinations, including SystemID and CAD download – making engineering faster, safer, and easier.
