Compact part-turn actuator
13 October 2016
The ED/EQ series of compact part-turn actuators from AUMA Industry & Marine is suitable for automating butterfly and ball valves. With eight sizes covering a torque range of 25 to 600Nm, the ED/EQ series represents AUMA’s low-torque segment. The company’s full product portfolio provides torques up to 675,000Nm.

Operating times for 90° travel ranges between 15 and 160s, depending on the size, and are factory set.
Each size is available with at least one variant offering a stall-proof motor (duty type S1 – 100 %), making these actuators well suited to modulating duties. All have handwheels for emergency manual operation. For the EQ actuators, mechanical end stops limit the angle of travel during manual operation. All sizes are available with at least three output mounting flanges. The separate plug-in coupling allows the actuator to be matched easily to the valve shaft and simplifies installation.
ED and EQ actuators are designed for integration into simple distributed control systems, and are said to have low energy consumption. In their basic versions they have two limit switches for motor cut-out when the valve reaches the end of its travel. As an option, the actuators can be equipped with binary inputs for operation commands by integrating reversing contactors, positioners, and analogue position feedback signals. A Profibus interface is also possible. The basic versions offer protection to IP67, with IP68 as an option.
