Technical data AUMA worm gearboxes and primary
reduction gearing – version with worm wheel made of
bronze
Application
For motor and manual operation of valves (e.g. butterfly and ball valves), especially suitable for modulating duty.
For special applications, e.g. dampers or gas diverters, special sizing is required.
Features and functions
Type of duty Short-time duty S2 - 15 min. (open-close duty)
Intermittent duty S4 - 25 % (modulating duty)
Version Standard: clockwise rotation RR, counterclockwise rotation LL, option: RL or LR
Self-locking The gearboxes are self-locking when at stand-still under normal service conditions; strong
vibrations may cancel the self-locking effect. While in motion, safe breaking is not
guaranteed. If this is required, a separate brake must be used.
End stops Positive for both end positions by travelling nut, sensitive adjustmen
Strength of end stop Guaranteed strength of end stop (in Nm) for input side operation according to AWWA
Swing angle
GS 50.3 – GS 125.3
Swing angle
GS 160.3 – GS 250.3
Standard: Fixed swing angle up to max. 100°; set in the factory to 92° unless ordered otherwise.
Options: adjustable in steps of:
10°– 35°, 35° – 60°, 60° – 80°, 80° – 100°,
100° – 125°, 125° – 150°, 150° – 170°, 170° – 190°
Swing angle > 190°, multi-turn version without end stops, version GSD
Standard: adjustable 80° – 100°; set in the factory to 92° unless ordered otherwise.
Options: adjustable in steps of: 20° – 40°, 40° – 60°, 60° – 80°,
Swing angle > 100°, multi-turn version without end stops, version GSD
Mechanical position indicator Standard: Pointer cover for continuous position indication
Options: Sealed pointer cover for horizontal outdoor installation 10)
Protection cover for buried service instead of pointer cover
Input shaft Cylindrical with parallel key according to DIN 6885.1 (refer to tables page 1 and page 2)
Operation
Motor operation With electric multi-turn actuator, directly or through primary reduction gearing VZ/ GZ
Flanges for mounting of actuator, refer to tables page 1 and page 2.
Manual operation Via handwheel, directly or through primary reduction gearing VZ/ GZ
Available handwheel diameters, selection according to the max. output torque:
