Operation instructions Worm gearboxes GS 50.3 – GS 250.3 1. Safety instructions 1.1 Range of application AUMA worm gearboxes GS 50.3 – GS 250.3 are used for the operation of valves (e.g. butterfly valves and ball valves). They are designed for manual operation as well as motor operation in conjunction with electric actuators. For other applications, please consult us. The manufacturer is not liable for any possible damage resulting from use in other than the designated applications.
Worm gearboxes GS 50.3 – GS 250.3 2. Operation instructions Technical data Features and functions Version Housing material Self-locking Output torques Standard: clockwise rotation RR, counterclockwise rotation LL, option: RL or LR Standard: cast iron (GJL-250), Option: spheroidal cast iron (GJS-400-15) 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.
