Festo DFPD quarter-turn actuator

The DFPD quarter-turn actuator is designed to be used in a variety of sectors and markets. It has a modern, simple and compact design and can be used with ball valves, shut-off valves or air dampers in the chemical, pharmaceutical or beverage industry or for water treatment and other areas of process automation.

The single-acting version is compact and modular. Due to the optimised spring design it can be configured in increments of 0.5 bar for more efficient use. With the nine different spring combinations, the DFPD quarter turn actuator meets the most precise operating pressure requirements of between 2 and 6 bar. The rotation angle for standard sizes is up to 90° and for the sizes 40, 120, 240 and 480 the angle can be 180°.

The basic version of the DFPD is suitable for temperatures between -20 and +80°C. The low-temperature variant is designed for arctic regions and covers a temperature range of -50 to +60°C. The high-temperature variant can be used at temperatures of between 0 and +150°C. With its versatile and corrosion-resistant surface coatings, the actuator can also be reliably and flexibly 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.
