8 Maintenance and Repair
8.1 General Information
The
dosing valve
is a high-quality precision device which will not fail if treated correctly and will operate
almost maintenance-free. Always keep clean and observe minimum instructions to maintain a long life of the
valve. Always use clean and filtered material only. The control air must also be clean and should be slightly
oiled, if necessary. Maintenance also depends on the individual operating conditions and the type of media
used.
CAUTION
Before starting any maintenance or repair work, ensure that all air-operated tools are
depressurized and disconnected from the air supply.
Disconnect the main power plug.
Make sure
the pneumatic / hydraulic system is pressure-less.
IMPORTANT
This chapter does not tell you how to repair the device after damage. Repair work
should only be performed by a specialized technician or the maintenance team or the
manufacturer.
8.2 Routine Tasks
The maintenance intervals below refer to a single-shift operation. If the device is run in a multi-shift operation
or is operated very often, the maintenance intervals become shorter. Also, additional factors such as
cleanliness or work surroundings have to be taken into account.
