10. Turn multi-turn actuator with handwheel in direction OPEN until valve flange
and output drive type A are firmly placed together.
11. Tighten screws [5] between valve and output drive type A crosswise applying
a torque according to table.
4.4.3. Multi-turn actuator with output drive type B: mount
Figure 14: Mounting output drive types B
[1] Multi-turn actuator
[2] Valve/gearbox
[3] Valve/gearbox shaft
Procedure
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.
