SQ PART-TURN ACTUATORS WITH BASE AND LEVER AND SA/GF
SA multi-turn actuators com- bined with GF gearboxes act as lever actuators. Lever gearboxes are derived from GS part-turn gearboxes wi- thregard to design. Various reduction ratios are achieved by integratingprimary reduc- tion gearings. The following indications serve the purpose of a rough outline. Please refer to the separate data sheets for more detailed informa- tion. Gearboxes provided for modulating applications are equipped with a worm wheel made of bronze. The nominal torque is reduced for this ver- sion.
Combinations with part-turn gearboxes with base and lever
If due to a lack of space, valves such as butterfly valves can only be operated via a lever arrangement.
For higher torque requirements, the multi-turn actuators SA can be combined with a part-turn gearbox with base and lever. The gearboxes are based on the worm gearboxes GS, which can be converted by mounting base and lever. Since this can also be done afterwards, this results in considerable advantages in stock-keeping.
