Festo's quarter turn actuator sets new standards in process automation

08.03.2018 -

Festo’s DFPD quarter turn actuator can be used in a variety of sectors and markets. Its modern, simple and compact design impresses, whether it is 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 rack and pinion combination is a great addition to the market, in both the single and double-acting versions with maximum torque of up to 2300 Nm.

Flexible in operating pressure
The single-acting version of this new quarter turn actuator is compact and modular. Thanks 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 quarter turn actuator DFPD meets the most precise operating pressure requirements of between 2 and 6 bar. The rotation angle for standard sizes is up to 90 degrees and for the sizes 40, 120, 240 and 480 it even rises to 180 degrees.

The basic version of the DFPD is suitable for temperatures between -20 and 80 degrees Celsius. The low-temperature variant is designed for arctic regions and covers a temperature range of -50 to 60 degrees Celsius. The high-temperature variant can be used at temperatures of between 0 and 150 degrees Celsius. 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 about 5 degrees at both ends, ensuring high flexibility during operation.

A complete package covering the entire value chain
In combination with the CMSX positioner, it is ideally suited for the analogue control of quarter-turn actuators in dosing tasks. Furthermore, the sensor boxes SRBC/SRBE/SRBG enable simple digital control and full position sensing. And this is possible outdoors as well as in potentially explosive environments. The Namur valves VSNC are certified worldwide in accordance with all the current standards. For safety-oriented applications, the robust pilot valves VOFC and VOFD are perfect additions. The solenoid valves can be widely used and meet the highest safety standards (up to SIL3, explosion protection). This allows Festo to provide complete automation of quarter-turn actuators for a large range of applications.
