The Model 455 dispensing valve is a pneumatically operated, normally closed pinch valve with a disposable fluid path. It was designed to dispense a variety of medium to high viscosity light-curable adhesives, inks, and cyanoacrylates with extreme precision. The valve's micrometer control feature allows users to precisely adjust the material flow, ensuring that materials are dispensed consistently and accurately.

The Model 455's disposable fluid path carries materials from the material reservoir to the dispense tip. Fluids are sealed within the fluid path, preventing contact with the valve's inner components and ensuring a contaminate-free dispensing process. The fluid path is easy to replace and requires minimum clean-up, allowing for rapid material changeover.

Features

N/A

  • Disposable fluid path that carriers materials from the material reservoir to the dispense tip
  • Fluids remain contaminate-free during dispensing
  • Prevents air entrapment during the dispensing process
  • Allows for easy product changeover with minimal cleanup
  • Fluid never comes in contact with the valve's inner components, reducing maintenance and extending the valve life

Additional Information

N/A This valve can be supplied with fluid paths of varying materials and sizes for optimum material compatibility.

The dispensing valve can be integrated into an automated dispensing system or can be paired with the Dymax® DVC-345 Digital Valve Controller and a material reservoir to create a bench-top dispensing system.
