Festo has leveraged its design capability, manufacturing scale and logistical strengths to offer customers a modern quarter turn actuator (DFPD), with price reductions compared with previous models. 

As a leading provider of industrial automation solutions, Festo is no stranger to process automation, says the company. The DFPD fits into the existing range alongside pilot solenoid valves, analogue positional controllers, switch boxes, and ball and butterfly valves giving customers matched components that are easy to configure, purchase and assemble. 

The updated configurable DFPD ‘sets a new benchmark for quarter turn actuators’ and offers a simple, compact and modular design. The DFPD is ideal for many tasks in the process industry, including automating butterfly or ball valves and air dampers in the chemical, beverage and pharmaceutical industries, as well as in water treatment. It can be used as an individual actuator or combined with other components, such as sensor boxes, positioners and pilot valves, as part of a complete, integrated single manufacturer automated process valve system, delivering reliability and ensuring that everything works together perfectly, promises Festo.

With a torque range from 10 to 480 Nm, a rotation angle of up to 180° and corrosion-resistant versions, the versatile and modular single or double-acting DFPD performs well across a broad range of applications and industries. Its compact rack-and-pinion combination is easy to install, even when space is at a premium. Both the end stop positions can be adjusted by ± 5° for increased flexibility during commissioning. The direction of rotation can be selected and the rotation angle for standard sizes is up to 90°, rising to 180° for the 40, 120, 240 and 480 sizes. 

Thanks to its innovative spring cartridge design, the single acting DFPD’s pressure range can be easily optimised for the task in hand. Nine different spring combinations allow pressures from 2 to 6 bar to be efficiently configured in increments of 0.5 bar to meet the most precise operating pressure requirements. The standard version is suitable for temperatures between -20 and +80 °C, with variants also available to operate reliably at either low or high extreme temperatures, ranging from -50 to +150 °C. 

With optional corrosion-resistant surface coatings, the DFPD can also be reliably used in harsh conditions. It can be mounted anywhere and its range of variants, the standardised hole patterns to NAMUR VDI/VDE 3845 for pilot valves, as well as its many compatible peripheral components mean that it can fulfil a large variety of applications.
