6.4.1 Air requirement
The air requirement depends on the type of actuator fitted. The following tables
show guideline values at an air pressure supply of 6 bar per valve size and the
corresponding actuator size used as a standard.

6.4.2 Establishing the Compressed Air Supply
A prerequisite for the reliable operation of the valve is that the compressed air
hoses are cut exactly square.
Tools required:
• A hose cutter
Carry out the following steps:
1.
Depressurize the pneumatic connection at the place where you are working.
2. Use the hose cutter to cut the pneumatic hoses square.
3. Connect a hose to the valve.
®
The compressed air supply has been established.
Hint!
It must be possible to regulate the supply of compressed air for
precision control of the valve position. Therefore, the use of a
positioner is recommended. Various standard versions can be ordered
from the manufacturer, see Section 10.6, Page 35.
6.5 Electrical connections
Prerequisite:
• The valve has been fitted correctly, see Section 10.7, Page 36.
• Positioner is installed according to the respective manual. Overview of
positioners see section Section 10.6.1, Page 36.
