Rotary actuator DAPK series

pneumaticrack-and-pinionstainless steel

The DAPK rotary actuator is characterised by an exceptionally high level of performance, great ease of use, positioning accuracy and long life. It features a patented rack and pinion slack adjustment mechanism. The angle of rotation can be adjusted between 0° and 180°. A 3° overrun beyond 180° is also provided at each side. The end position stops can be either elastic mechanical stop (for application with reduced mass and velocity) or hydraulic shock absorbers. The end position can be detected using either the magnetic version, which is suitable for magnetic sensors, or the version suitable for inductive sensors. Versions with two, three and four positions are also available. The third and fourth position can be added at a later stage by installing the accessory provided. The versions with a pneumatic rotary distributor can be used to supply compressed air to the rotating plate from the inside, thus avoiding using external rotating pipes. In this case the rotating plate can be chosen among the one mounted in-line and that tilted by 90°. N.B.: We always suggest to use flow microregulators.During the setup of the actuator, start with CLOSE flow microregulators,and open gradually till the achievment of the required speed
