Model 475

Model 475 Closed Diaphragm Dispensing Valve


The Dymax Model 475 pneumatic, normally closed diaphragm valve is designed for use with low- to high-viscosity fluids such as light-curable adhesives, cyanoacrylates, and inks. The internal diaphragm design of the valve prevents fluid from contacting the actuating components within the valve while minimizing valve maintenance and production down-time. This feature of the valve makes it ideal for dispensing light-curing materials, solvent-based products, and reactive materials like cyanoacrylates and anaerobics. Accurate, repeatable dispensing can be achieved by utilizing the valves stroke adjustment to dial-in a desired shot volume.

While ideally suited for manual, semi-automated, and automated applications, the Model 475 diaphragm valve is also available in a wide variety of system packages paired with the Dymax DVC-345 bench-top valve controller and material reservoirs of various styles and sizes.

Model 475 Diaphragm Valve for Dispensing Adhesives

The Dymax Model 475 dispensing system utilizes a pneumatic, normally closed diaphragm valve to accurately dispense low- to high-viscosity fluids. The internal diaphragm design of the valve prevents fluid from contacting the actuating components within the valve, decreasing wear on the valve's actuating components and minimizing valve maintenance and production down-time. This feature of the valve also makes the system ideal for dispensing reactive materials like cyanoacrylates and solvent-based products.
