• Short-time duty s2 - 15 min [open-close duty]

• Intermittent duty s4 - 25 % [modulating duty]
They can either be operated in:

• Manual operation directly via handwheel

• Motor operation [electric multi-turn actuator]

• Gearbox is prepared for mounting an actuator flange

• Clockwise rotation at the input shaft results in clockwise shaft results in clockwise rotation at the output drive

• To reverse the direction of rotation of gk 14.2 - gk 25.2, a reversing gearbox gw 14.1 can be used.

• Direction of rotation at the output drive can be reversed for gk 30.2 - gk 40.2.

• Gk 10.2 - gk 25.2 are single stage gearboxes.
Gk 30.2 - gk 40.2 are double stage gearboxes. Design features:

• Torques up to 16,000 nm

• Reduction ratios from 1:1 to 1:22

• Output drive types according to iso or din standard
