Model 400
Model 400 Hand-Held Needle Closed-Valve System
Dymax Model 400 pneumatic, normally closed needle valve is designed to deliver precise dots or very fine beads of low- to medium-viscosity fluids such as light-curable adhesives and inks. The valve’s design is compact and lightweight, making it easy and comfortable to handle. Air pressure retracts the valve’s needle assembly from the seat allowing fluid to flow from the valve fluid inlet to the dispensing tip. When the air pressure is eliminated, the spring returns the needle back to its position, closing the fluid path and ending the dispense cycle. Accurate, repeatable dispensing can be achieved by utilizing the valve’s material flow adjustment to control the shot volume.
The Model 400 is available in several system packages, paired with the Dymax DVC-345 bench-top valve controller and material reservoirs of various styles and sizes. Additional accessories, like a valve stand and various style dispense tips, are also available for this system.
