Description

The Festo DFPD Series is a line of semi-rotary drives that feature a rack and pinion combination with a constant torque characteristic across the entire swivel range. The quarter turn actuators DFPD are ideal for automating butterfly valves, ball valves and air shut off valves. They can be used as an individual actuator or as part of a complete automated process valve system from Festo. With a torque range from 10 to 2,300Nm, a rotation angle up to 180° and corrosion-resistant versions, the single or double-acting DFPD is suitable for ball valves, butterfly valves or air dampers in the chemical, pharmaceutical and beverage industries, as well as for water treatment.
