Model 475 Diaphragm Dispensing Valve

Nature of Valve: Closed

The Dymax Model 475 pneumatic, normally closed diaphragm valve is designed for use with low- to high-viscosity fluids. 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 valve’s 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.

Features & Benefits

  • Internal diaphragm prevents fluid contact with actuating components within the valve to minimize damage to the components and necessary maintenance
  • Diaphragm design is suitable for low- to high-viscosity fluids including reactive and solvent-based materials
  • Stroke adjustment for precise control over dispensing volumes and shot-to-shot consistency (when used with the DVC-345 controller)
  • Lightweight so it’s easy to handle and mount in automated or bench-top systems
