ABSTRACT:
A device for delivering paints comprises a housing containing a rod which is movable by a microprocessor controlled pneumatic piston, to seal both ends of a discharge duct. The pneumatic piston is activated to move the rod to open both ends of the discharge duct for the delivery of paint. The rod can then be moved to close the discharge duct and avoid the drying of paint within the duct.
