Mounting and start-up
An operating pressure above the maximum
permissible operating pressure will damage
the solenoid valve.
− Observe the max. operating pressure (see
technical data in section 3.2).
− If necessary, use a pressure reducing valve
to restrict the operating pressure.
Risk of malfunction due to failure to comply
with required air quality.
− Only use supply air that is dry and free of
oil and dust.
− Read the maintenance instructions for up-
stream pressure reducing stations.
− Blow through all air pipes and hoses thor-
oughly before connecting them.
Operating medium for the booster valve
With internal pilot supply:
− Instrument air free from corrosive sub-
stances or nitrogen
− Operating pressure 1.4 to 6 bar

stances, air containing oil or non-corro-
sive gases

With external pilot supply over port 9
− Instrument air free from corrosive sub-
stances, air containing oil or non-corro-
sive gases
− Operating pressure 0 to 6 bar
Pilot air for the pilot valve

5.5 Changeover to external
pilot supply over port 9
If the solenoid valve is to be used to switch
the output signal (0 to 6 bar) of a positioner,
the pilot supply must be routed externally
over port 9.
Types 3963-XXXX0X4/-XXXXXX7
The pilot supply in these solenoid valves is
fed internally over port 4, if not specified
otherwise. To change to an external pilot
supply through port 9, proceed as follows:
1. Undo the cap screw on the connection
plate and remove plate  and gasket
