7. Maintenance and re-
pair
The automatic valve is a maintenance-free
device.
In terms of operational safety, however, it is
recommended to check them for function
and to switch at least every three months
but no later than after 50,000 switching cy-
cles; and in case of difficult operating condi-
tions even more often.
Do not use harsh detergents or abrasives to
clean the housings.
7.1 Maintenance of rotary
actuator
In principle, it is possible to repair the pneu-
matic rotary actuator by replacing the seal
and wear parts sets.
7.2

Maintenance ball valve

Repair and maintenance of the seal and
wear parts of the butterfly valve must not be
carried out because it is about high-pres-
sure glued ball valve.
NOTE
We recommend that you have the repair
carried out by the company bar GmbH.
We will be pleased to offer you a corre-
sponding servicing, maintenance or re-
pair. Please contact the company bar
GmbH for this.
