Precision dosing valves with a needle assembly to dispense precise dots or very fine beads of low to medium viscosity adhesives and fluids such as anaerobics, activators, inks, gels, solvents, lubricants, chemicals and UV's.  Needle seal at tip end prevents dead space for very fast shut off when dispensing micro dots without drips. Needle valves are designed to apply micro shots without drips. The valve design is vertical with fluid flow from the side either by syringe, cartridge or fluid line feed (from pressure pot).  Use black fluid lines or feed tubing with UV cure adhesives.
