UV Cure liquid dispenser is designed to accept a 1 liter bottle of ultra-violet cure adhesives. There is no pouring needed (ie: you drop your 1 liter bottle of glue right into the dip-tube tank). Very little clean up is involved with this system and you do not smell the strong fumes of the glue as this is a contained system. The valve is designed to dispense thin and medium UV adhesives with precise deposits of glue with no dripping. The system has many ways to control the deposit: -needle size, tank pressure, - timer length control, -valve fine stroke adjustment.
