The working principle of the glue valve: when the glue is discharged, the compressed air is sent into the glue inlet of the glue valve body, and the glue is pressed into the glue inlet pipe connected with the piston cavity. When the piston is in the upper stroke, the piston cavity is filled with glue. When the dispensing needle is pushed down, glue is dispensed from the nozzle. The amount of glue dispensed is determined by the distance, pressure and time of the plunger, and the glue valve itself can fine-tune the amount of glue dispensed.
