Click2Contact

The Festo DFPD quarter turn actuator offers a simple, compact and modular design. The DFPD is suitable 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 or as part of a complete, integrated automated process valve system.

The rack-and-pinion combination is available in both single- and double-acting versions with maximum torque of up to 2300 Nm. The rotation angle for standard sizes is up to 90° and up to 180° with the double-acting version. The standard version is suitable for temperatures between -20 and +80°C, with variants also available that are designed to operate reliably at either low or high extreme temperatures, ranging from -50 to +150°C.

With its versatile and corrosion-resistant surface coatings, the actuator can also be used in harsh conditions. It can be mounted anywhere and the end positions can be adjusted by ±5° at both ends, ensuring high flexibility during operation.

The full range of variants, the standardised hole patterns to NAMUR VDI/VDE 3845 for pilot valves, as well as its many compatible peripheral components means that it can fulfil a large variety of applications.
