Ideal for automated assembly processes, the 741MD-SS MicroDot™ valve has an adjustable needle stroke with a unique calibration feature that allows the user to maintain exact deposit size when dispensing fluid.
The stainless steel shutoff needle seats in the hub of the dispensing tip rather than the valve body. This design minimizes dead fluid volume by having fluid cutoff occur as close as possible to the dispensing orifice. Because the needle seat is part of the dispense tip itself, the seat can be renewed by simply replacing the disposable tip.
The complete system includes the 741MD-SS dispense valve, ValveMate™ 8000 controller, fluid reservoir and dispense tip.
