8 Maintenance and Repair
8.1 General
The
MPP-Speed
Micro Point Pulse Valves are high precision tools. Always keep clean and observe mini-
mum instructions to maintain a long life of the valve. We recommend lubricating moveable parts regularly
and greasing threads, especially the nozzle threads, when replacing or cleaning the nozzle. Always use
clean and filtered material only. 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.
Before opening the spray valve it must be disconnected from the air and fluid supply.
Otherwise, ejected components can cause injuries.
