The model 455 dispensing valve from this company 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 precision. The valve’s micrometer control feature can allow users to precisely adjust material flow for consistent and accurate materials dispensing .

The model 455’s disposable fluid path carries materials from the material reservoir to the dispense tip. Fluids are sealed within the fluid path, reportedly preventing contact with the valve’s inner components and allowing a contaminate-free dispensing process. The fluid path is reportedly easy to replace and requires minimal cleanup, allowing for rapid material changeover.  Fluid paths of varying materials and sizes are available for optimum material compatibility.
