4.1. Mounting position
When using grease as lubricant, the product described herein can be operated in
any mounting position.
When using oil instead of grease within the actuator gear housing, perpendicular
mounting position is specified whereby the flange is pointing downward.The type of
lubricant used is indicated on the actuator name plate (short designation F...= grease;
O...= oil).

4.2.1. Design of output drive type A
Output mounting flange [1] with axial bearing stem nut [2] form one unit.Torque is
transmitted to valve stem [3] via stem nut [2].

To adapt the actuators to available output drive types A with flanges F10 and F14
(year of manufacture 2009 and earlier), an adapter is required.The adapter can be
ordered from AUMA.
4.2.2. Design of output drive types B and E
Connection between hollow shaft and valve or gearbox via output drive sleeve fixed
to the hollow shaft of the multi-turn actuator via retaining ring.
When exchanging the output drive sleeve, later retrofitting to a different output drive
type is possible
