2 Installation Caution! Versions designed to handle temperatures up to 200 °C must be fitted with the dark gray graphite supplied with the valve. Do not use the UDP seals available as accesso - ries as they are only suitable for tempera - tures up to 150 °C. 2.1 Mounting position 4 Choose the place of installation where the ambient temperature do[...]

3 Attaching the actuator to the valve If the actuator has not already been mounted on the valve by the manufacturer or when the original actuator on a valve is to be replaced with a controller with electric actuator, proceed as follows. Note! Fasten the actuator and valve together either at the valve connection or at the intermedi - ate insulating [...]

4 Electrical connections Upon installing the electrical cables, you are required to observe the regula - tions concerning electrical power in - stallations according to DIN VDE 0100 as well as the regulations of your local power supplier. Use a suitable power supply to ensure that no dangerous voltages from the system or parts of the system reach t[...]

7 Maintenance The control valve is subject to natural wear. Depending on the conditions the valve is op - erated in, it needs to be checked at regular intervals. If leakage to the atmosphere occurs, remove the valve from the pipeline and replace the damaged parts. Warning! For maintenance work on the valve, make sure the relevant section of the pip[...]
