Dymax Dispense Valves and Controllers, Model 828

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 a 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 in [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.
