Installation and maintenance guide
Servicing
The manual spray valve is a high-quality precision device which will usually operate fault-free and without any servicing
if handled correctly, provided that only clean, filtered material is used. It is also essential that the control air be clean and,
ideally, supplied to the spray valve lightly oiled. Individual operating conditions and the properties of various materials
require a minimum of care to be given to the device.
Before beginning any servicing work:
> Put on personal protective equipment.
> Switch off device and prevent it from being switched back on.
> Switch off pressure plant and prevent it from being switched back on. Depressurise all supply pressure lines and
disconnect them from the device.
NOTE!
Remaining spray media should be dealt with at appropriate time intervals.
Cleaning
The valve must be cleaned when
> it is soiled by use
> a different material is to be used
> wearing parts have to be replaced.
This applies in particular to the nozzle needle, the sealing bush and the nozzle.
IMPORTANT!
Do not use any sharp sharp-edged, metallic aids for external cleaning; only use soft brushes.
