In process technology plants, liquids, gases, vapours, and granulate need to pass through pipelines. Industrial valves are used to inhibit or release medium flow as well as to control the resulting flow rate by opening or closing the valves. AUMA actuators are remotely controlled from the control room to operate valves.
Electric multi-turn actuators by AUMA are used e.g. for the automation of gate valves or globe valves. They are the most versatile products within the AUMA family.
Electric part-turn actuators by AUMA are used where an automatic, electrically operated movement at a swing angle of less than 360 ° has to be implemented as it is the case for valves like butterfly and ball valves.
To perfom linear movements, e. g. in case of globe valves, the multi-turn actuator SA ... can be combined with the linear thrust unit LE, forming an electric linear actuator. In case a lever arrangement has to be operated, the linear thrust unit can be mounted on a base.
Multi-turn gearboxes can be formed by combining multi-turn actuators SA ... with AUMA spur and bevel gearboxes to increase the torque or to reposition the output shaft. The gearboxes can of course also be used on manually operated valves.
AUMA part-turn gearboxes are used wherever a 90° swivel movement is required for the operation of a valve or damper.
Product selection in favour of actuators with integral controls saves time-consuming project planning, installation, and additional documentation which is required when selecting external controls.
Parallel control, fieldbus, or both for reasons of redundancy? When opting for fieldbus, which protocol to use? Irrespective of your decision on the interface, AUMA actuators can be equipped with the suitable interface to match all systems established within process control engineering.
