The dispenser valves, Diaphragm Valves are designed to dispense low viscosity materials. Since the parts that are in contact with liquid are made of fluororesin, they have excellent chemical resistance. The diaphragm is used for the seal of the valve and this prevents the liquid from penetrating into the drive body. The light and compact design makes it easy for mounting flexibility and easy integration into automated machine or used with multiple connections. A stroke control adjustment which is the flow regulating screw makes it easy to fine tune shot sizes by controlling the opening and closing strokes of the valve.
