AUMA SAExC 16.1 - Multi-turn Actuator Mounting to Valve;Gearbox

4.2. Multi-turn actuator mounting to valve/gearbox
4.2.1 Output drive types B1, B2, B3, B4, B, and E
Application For rotating, non-rising valve stem.
Design Output drive type bore with keyway:
Type B1 – B4 with bore according to ISO 5210.
Type B and E with bore according to DIN 3210.
Later change from B1 to B3, B4, or E is possible.
Information Spigot at flanges should be loose fit.
Mounting the multi-turn actuator
1. Check if mounting flanges fit together.
2.
Check whether bore and keyway match the input shaft.
3. Thoroughly degrease mounting faces of the mounting flanges.
4. Apply a small quantity of grease to the input shaft.
5. Mount multi-turn actuator and ensure that the spigot mates uniformly in
the recess and that the mounting faces are in complete contact.
6. Fasten multi-turn actuator with screws according to table 1.
7. Fasten screws crosswise with a torque according to table 1.
