Multi-spring diaphragm pneumatic actuators Festo
DAPS quarter turn actuators are specially designed for the requirements in the process industry. The torque is produced by the yoke mechanism. This is an advantage for overcoming the valve breakaway torque. Due to their robust design and the range of torques, DAPS actuators are mainly used to control valves through which various media flow and whose angle of rotation is limited to 90 °, e.g. ball valves and butterfly valves.
