Mounting

7.1

Actuator check

- Is the actuator filled with the appropriate oil type?
- Is enough oil in the actuator?
- Did you fasten the separately delivered vent screw in the highest bore (depending on the mounting
orientation)?
- Has the actuator integrated or separate electronic unit?
7.2

Mounting orientation

All mounting orientations seen in Figure 2 are permissible. To facilitate mounting and maintenance,
however, it is recommended to use orientation IMB 3.
7.3

Mounting instructions

- Make sure that the actuator is accessible from all sides to ensure convenient handwheel operation,
electrical connection, and replacement of assemblies.
- Avoid direct exposure to rain, snow and other environmental influences. Select the mounting site
accordingly.
- Exclusively mount the actuator on a rigid, non-vibrating support to avoid relative motion between
the actuator and the valve.
- When mounting the actuator close to heat sources use an insulating layer or shielding.
