Model 830 Disposable Fluid Path Pinch Valve

Precise Material Control And Larger Flow Rates

Nature of Valve: Closed

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 minimum clean up, allowing for rapid material changeover. The standard Model 830 valve is supplied with 0.375″ [9.53 mm] OD black polyethylene tubing.

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.

Features & Benefits

Features Benefits
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
  • Allows for 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, extending its life, and cutting down on necessary replacement
Adjustable suck-back control
  • Eliminates drooling and filming over of the nozzle for a clean, drip-free dispense when dispensing thin or stringy materials
Able to dispense from pressurized cartridges, bottles, and pails (requires appropriate reservoir hardware)
  • Compatible with most standard fluid packages and delivery systems
  • Easy to handle and mount in automated or bench-top systems
