Valve Dispensing Systems
Dymax Corp.’s new Model 475 valve dispensing systems utilize a pneumatic, normally closed diaphragm valve to accurately dispense low- to high-viscosity fluids. The design of the internal diaphragm and adjacent parts prevents migration of fluid into the actuating section within the valve. The toughness of the diaphragm, along with the selection of appropriate materials for component construction, ensures long diaphragm and valve life between maintenance schedules. These features also make these valve systems ideal for dispensing light-curable materials as well as reactive materials such as cyanoacrylates, anaerobics, and solvent-based products. Accurate, repeatable performance is easily achieved by utilizing the valve’s stroke adjustment knob to precisely dial in a desired shot volume. The included 25-micron air filter regulator permits the passing of only clean, dry, particulate-free air, ensuring the system’s long and continuous life. The regulator includes an integrated shutoff valve and pressure exhaust to quickly and safely depressurize the system, eliminating the need for the operator to open and close the regulator.
