Product description
Purpose
The needle metering valve is used for dosing low-
viscosity lubricants.
Labelling
The needle metering valve is labelled according to the
model code (Figure A/No. 6).
Functionality
Due to the compressed air connections, the needle
metering valve can be controlled externally via a 5/2-
way valve (Figure D/No. 10). This initiates dosing in
the hydraulic section, provided the needle metering
valve is connected to an active pump. The desired
dosing volume is continuously adjustable in the range
from 3 mm
to 200 mm

(Figure A/No. 5). A locking screw (Figure A/No. 4)
is provided to retain the set quantity. The vent with
hose connection (Figure B/No. 7) permits the clean
discharge of the medium.
