Abstract

A main needle valve for an electrostatic sprayer has an optoelectronic sensor device with light wave conductors (20,21) with their front surfaces facing a reflex element (12) for a structural link (10) moved by the valve needle (1), which is remotely controlled to slide between two indexing positions. The optoelectronic sensor senses an indexing position and generates a corresponding sensing signal.
