DFPB pneumatic quarter turn actuators from Festo are suitable for wastewater treatment plants, pharmaceutical industry and food production plants. These actuators can be used to perform opening and closing movements in process valves. The innovative housing concept means that the same actuator can be mounted on both right-closing and left-closing process valves.

When combined with electro-pneumatic position controllers, the pneumatic quarter turn actuator can also be used for high-precision positioning, especially with ball and plug valves, shut-off and butterfly valves.

The DFPB pneumatic quarter turn actuator offers a number of advantages that make it suitable for demanding applications. DFPB pneumatic quarter turn actuator has a high corrosion resistance and exchange of seals is made easy, since no special tools are required.

The new actuator is designed according to the rack-and-pinion principle. Quarter-turn actuators based on this principle exhibit an identical torque characteristic across the entire rotation angle range.

DFPB pneumatic quarter turn actuators are also compact, with single-acting and double-acting actuators constructed from the same housing design. A new pressure dependent lip-seal minimises frictional loss and ensures a longer service life.
