To ensure safe device operation, the maintenance instructions included in this manual Maintenance must be observed. Any device modification requires prior consent of the manufacturer. 1.2. Range of application AUMA part-turn actuators are designed for the operation of industrial valves, e.g. butterfly valves and ball valves.
1, 2, 21, and 22. If temperatures >40 °C are to be expected at the valve mounting flange or the valve stem (e.g. due to hot media), please consult AUMA. Temperatures > 40 °C are not considered with regards to the non-electrical explosion protection.

Ex marking Type and size These instructions apply to the following devices types and sizes: Part-turn actuators for open-close duty: SQEx 05.2, 07.2, 10.2, 12.2, 14.2 Part-turn actuators for modulating duty: SQREx 05.2, 07.2, 10.2, 12.2, 14.2 Ex marking Table 1: Marking for explosion protection (with example)
A part-turn actuator is an actuator which transmits a torque to the valve for less than one full revolution. It need not be capable of withstanding thrust. AUMA part-turn actuators are driven by an electric motor. A handwheel is provided for manual operation. Switching off in end positions may be either by limit or torque seating.
