New DFPD quarter turn actuators for process automation

Festo introduces a new range of
quarter turn actuators designed to set new standards in process automation.

The modular, resilient and
versatile DFPD quarter-turn actuators from Festo feature a rack and pinion
combination to meet the many requirements of 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 industries, water treatment and other areas of process automation.

Flexible in operating pressure

The single-acting version of
this new quarter turn actuator is particularly compact and extremely modular. Key
features include an optimised spring design allowing configuration in increments
of 0.5 bar for more efficient use; nine different spring combinations meeting the
most precise operating pressure requirements between 2 and 6 bar; rotation
angle for standard sizes up to 90¡ and for sizes 40, 120, 240 and 480 rising to
180¡; and corrosion-resistant surface coatings offering reliability and
flexibility in harsh conditions.

The basic version of the DFPD is
suitable for temperatures between -20¡C 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

DFPD quarter-turn actuators 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, the DFPD 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 even outdoors as well
as in potentially explosive environments.

The NAMUR valves VSNC are
certified worldwide in accordance with all the current standards while the
robust pilot valves VOFC and VOFD are perfect for safety-oriented applications.
The solenoid valves 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.
