Model 400 Hand-Held Needle Valve Systems


Dymax Model 400 pneumatic, normally closed needle valve is designed to deliver precise dots or very fine beads of low- to medium-viscosity fluids. The valve’s design is compact and lightweght, 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.

Special Features and Benefits of the Model 400 Dispensing System:

  • Material flow adjustment on valve for precise control over dispensing volumes
  • Shot-to-shot consistency (when used with the DVC-345 controller)
  • Lightweight, wand-style valve body. Easy and comfortable to handle
  • Able to dispense from pressurized cartridges, bottles, and pails (requires appropriate reservoir hardware)
  • Compatible with most standard fluid packages and delivery systems
