ABSTRACT:
A material dispensing valve finding particular application in the robotic dispensing of sealants, adhesives, etc. in a desired pattern on a workpiece. The dispensing valve comprises a unique actuating arrangement wherein back to back pancake cylinders are moveably arranged within a housing and, depending upon how the cylinders are actuated, three or four dispense rate positions can be provided. The dispense rate positions of the valve are preferably coordinated with the rate of movement of the robotic system so that the dispense rate is appropriate for the rate of movement.
