Model 300 Hand-Held Valve Systems

Nature of Valve: Closed

Dymax Model 300 dispensing systems feature a pneumatic, normally closed diaphragm valve that is designed for use with low- to high-viscosity fluids. The valve’s design is compact and lightweight, making it easy and comfortable to handle. The internal diaphragm design of the valve prevents fluid from contacting the actuating components within the valve. This reduces damage and wear to the actuating components, extending the life of the valve and minimizing necessary valve maintenance. This feature also makes this valve ideal for dispensing light-curable materials, solvent-based products, and reactive materials like cyanoacrylates and anaerobics. Accurate, repeatable dispensing can be achieved by utilizing the valve’s material flow adjustment to control the shot volume.

The Model 300 is available in several system packages, paired with the Dymax DVC-345 valve controller and material reservoirs of various styles and sizes.

Special Features of the Model 300 Dispensing System:

  • Internal diagram in valve prevents fluid contact with actuating components within the valve
  • Valve features material flow adjustment for precise control over dispensing volumes
  • Lightweight, wand-style valve body for easy and comfortable handling
  • High-quality, air precision regulator supplied for precise fluid control
  • Air filter regulator includes an integrated shutoff valve and pressure exhaust to quickly and safely depressurize the system, eliminating the need for the operator to open and close the regulator
  • Easy-to-open, swing-down toggles on the bottle and pail reservoir
