Versatility meets design
Modular, resilient, versatile – these are the core properties of the quarter turn actuator DFPD from Festo. This rack and pinion combination is thus the perfect actuator for many requirements in the process industry.
Thanks to its versatility and flexibility, the DFPD 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 particularly compact and extremely 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° and for the sizes 40, 120, 240 and 480 it even rises to 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 °C to +60 °C. The high-temperature variant can be used at temperatures of between 0 °C 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.
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, e.g. 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.
