SA/GHT MULTI-TURN ACTUATORS
GHT worm gearboxes in combina- tion with SA multi-turn actuators act as multi-turn actuators with
high output torques. The torque range increases nearly fourfold when combining GHT gearboxes with SA actuators. This type of torque requirements occurs e.g. for large gate valves, weir pen- stocks or dampers.
If the drive shaft is to be displaced by 90°, combinations of the multi-turn actuators SA with AUMA bevel gearboxes GK are used. The output torque can be increased many times.
