The electromagnetic valve DLK22KV, thanks to the construction methods and employed materials, is
easy to maintain. A minimal, simple, accurate and constant maintenance allows a long-lasting and regular
functioning of the valve, keeping uncharged its performance.
• For the general cleaning of the valve don’t use metallic, sharp or pointed objects. Use only
soft brushes or cotton rags.
• All the maintenance works on the valve must be performed by qualified personnel and
after the supply pressure system has been discharged
• For the nozzle cleaning use only cleaning needles supplied by the valve manufacturer: if
you use other sharp objects the nozzle could be damaged
• Use only original spare parts
• The valve must be washed only and exclusively with water, especially if you need to replace
the nozzle or the needle
• Every evening and if you expect a long work break put some grease on the nozzle tip
