Request Information
The Model 830 dispensing valve is a normally closed disposable fluid path valve that provides larger material flow rates while still maintaining precise control. This dual-piston pinch valve is used with many low- to high-viscosity materials and features a suck-back control to handle stringy and tacky materials with no mess. The valve's main feature is its disposable fluid path which 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 minimal cleanup, allowing for rapid material changeover. The standard Model 830 valve is supplied with 0.375 in [9.53 mm] OD black polyethylene tubing.

Features

N/A

  • Disposable fluid path that carries materials from the material reservoir to the dispense tip
  • Fluids remain contaminate-free during dispensing
  • Prevents air entrapment during the dispensing process
  • Easy product changeover with minimal clean up
  • Fluid never comes in contact with the valve, reducing valve maintenance and extending the life of the valve
  • Over-pinch adjustment prevents tubing damage and extends life
  • Adjustable suck-back control eliminates drooling and filming over nozzle
  • Drip-free dispense when dispensing thin or stringy materials
  • Dispenses from pressurized cartridges, bottles, and pails (requires appropriate reservoir hardware)
  • Lightweight, easy to handle and mount in automated or bench-top systems

Additional Information

N/A The Model 830 valve can be integrated into an automated dispensing system and controlled with a three-way solenoid valve or paired with the Dymax® DVC-345 Digital Valve Controller and a material reservoir to create a bench-top dispensing system.
