Application
Manual operation and motor operation of valves (e.g. butterfly valves and ball valves)
Features and functions
Type of duty Short-time duty S2 - 15 min. (open-close 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 adjustment
Strength of end stop Guaranteed strength of end stop (in Nm) for input side operation
