Model 455 Disposable Fluid Path Pinch Valve


Fluid Path Pinch Valve

Nature of Valve: Closed

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 low- to medium-viscosity materials 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. 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.

Features & Benefits


Features Benefits
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 valve maintenance and extending the life of the valve

Over-pinch adjustment
  • Prevents tubing damage, allowing users to secure millions of cycles from the tubing before replacement is required

Stroke adjustment for precise, micrometer control over dispensing volumes

Able to dispense from pressurized cartridges, bottles, and pails (requires appropriate reservoir hardware)
  • Compatible with most standard fluid packages and delivery systems

Lightweight
  • Easy to handle and mount in automated or bench-top systems
