Product Overview
Description of the Model 828 Dispensing Valve
The Model 828 pinch valve is a normally open, disposable fluid path valve designed to
provide larger flow rates while still maintaining precise control over flow rate. This dual-
piston pinch valve works great with many low-to-medium viscosity materials and
features a suck-back control so it can handle stringy and tacky materials with no mess.
The 828 pinch valve can be controlled by a digital controller, such as the DVC-345
digital valve controller, or by a four-way solenoid valve. The Model 828 is featured in
several filling systems.
CAUTION!
valve will no longer have the force to prevent materials from flowing.
Precautions should be taken to anticipate unwanted dispensing.
