Mounting positions of local controls
Figure 15: Mounting positions
The mounting position of the local controls is implemented according to the order.
If, after mounting the actuator to the valve or the gearbox on site, the local controls
are in an unfavourable position, the mounting position can be changed at a later
date. Four mounting positions shifted by respectively 90° are possible (by maximum
180° into one direction).
