  • Page 4: Range Of Application

    Any device modification requires prior written consent of the manufacturer. 1.2. Range of application AUMA multi-turn gearboxes are designed for the operation of industrial valves, e.g. gate valves and globe valves. Other applications require explicit (written) confirmation by the manufacturer.

  • Page 5: Short Description

    GK 40.2 Short description Short description AUMA bevel gearboxes are multi-turn gearboxes transmitting a rotary movement to the valve. They are driven either via electric motor (by means of a multi-turn actuator) or manually (via a handwheel). The drive axle is perpendicular to the output axle, thus adjusting in a single stage...

  • Page 13: Assembly

    This chapter supplies basic information and instructions which should be heeded in addition to the operation instructions of the multi-turn actuator. When delivered with AUMA multi-turn actuators, the multi-turn actuator-gearbox Mounting positions combination is delivered in the ordered mounting position up to size GK 16.2. For packing reasons, multi-turn actuator and gearbox will be delivered separately from size GK 25.2.
