Product Description
- Thanks to its special design, the DAPS rotary actuator is ideal for use in the process industry. It is suitable for use with compressed air. Thanks to the connection diagram in accordance with Namur VDI/VDE 3845, solenoid valves can be easily mounted on the rotary actuator.
- The cover and housing of the DAPS rotary actuator are made of aluminium, while the shaft and screws are made of high-alloy steel. It also features seals made of FKM, NBR and PUR. The materials used are RoHS-compliant. The lever-rocker kinematics generate the torque required to overcome high breakaway torques in the valve, which is very advantageous. Thanks to their robustness and torque gradation, DAPS rotary actuators are mainly used to control media-flowing valves, such as ball valves and butterfly valves. The maximum angle of rotation is 90°. The rotary actuator impresses with its compact design, its torque curve adapted to process valves and its low wear, which is made possible by simple and robust mechanics.
