Maintenance

Needle metering valves are precision instruments that
are not susceptible to faults, given proper handling,
and operate largely without maintenance, assuming
that the application material is generally processed
in clean condition, not contaminated by foreign
particles. We recommend the following maintenance
intervals to optimise the service life:
WANN
Weekly
Weekly
Monthly
Annually
The specified maintenance intervals are for single
shift operation. Maintenance has to be carried out
more often depending on the field of application,
medium and in case of operation in more than
one shift.
CAUTION
All work on the system is basically
only to be carried out when it is at
a standstill. The pneumatic and
hydraulic systems have to be
de-pressurised. The pressure gauges
have to show 0 bar.
