5.3.3.1. Multi-turn actuator with output drive type B: mount

Procedure
SAREx 16.2 Control unit: electronic (MWG)
Figure 18: Mounting output drive types B
[1] Multi-turn actuator
[2] Valve/gearbox
[3] Valve/gearbox shaft
1. Check if mounting flanges fit together.
2. Check if output drive of multi-turn actuator [1] matches the output drive of
valve/gearbox or valve/gearbox valve shaft [2/3].
3. Apply a small quantity of grease to the valve or gearbox shaft [3].
4. Place multi-turn actuator [1] and ensure that the spigot fits uniformly in the recess
and that the mounting faces are in complete contact.
5. Fasten multi-turn actuator with screws according to table.
Information: We recommend applying liquid thread sealing material to the
screws to avoid contact corrosion.
6. Fasten screws crosswise to a torque according to table.
