Model 828 Dispensing Valve


The Model 828 normally open disposable fluid path valve is designed to provide larger flow rates while still maintaining precise control over material flow rate. This dual-piston pinch valve can be used with many low-to-high viscosity materials and features a suck-back control so it can handle stringy and tacky materials with no mess.

The valve also features a 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 828 valve is supplied with black polyethylene tubing but fluid paths of varying materials and sizes can be ordered for optimum material compatibility. This valve is compatible with a maximum tubing size of 0.375″ [9.53 mm] OD.

The Model 828 valve can be integrated into an automated dispensing system and controlled with a four-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


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’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
Adjustable suck-back control
  • Eliminates drooling and filming over of the nozzle for a clean, drop-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
Lightweight
  • Easy to handle and mount in automated or bench-top systems
