Description
Festo Quarter turn actuator DAPS
The compact and sturdy quarter turn actuator DAPS with lever kinematics is specially designed for the requirements of the process industry.
The torque is generated via a scotch yoke mechanism, which helps to overcome the valve’s high breakaway torques. Given their robustness and graduated torques, the quarter turn actuators DAPS are predominantly used to control valves through which various media flow and whose rotation angle is limited to 90°, e.g. ball valves and butterfly valves.
