The Fisnar DV509 is a lightweight diaphragm valve designed to dispense low to medium viscosity fluids while keeping wetted parts separate from the operating air supply. This is particularly useful in dispensing cyanoacrylate, reagents, UV adhesives, and aggressive substances. Diaphragm valves with stainless steel and UHMW (ultra high molecular weight) polyethylene bodies are also available. Micro shot sizes are fine tuned using the valve adjustment control. The valve design provides precise control and positive shut-off. This lightweight, 3 oz. valve is capable of 200 cycles per minute and withstands constant24-hour production cycling.
