Series 450 XT Snuff Back Valve

In response to your needs, Nordson EFD has designed and manufactured an innovative dispense valve specifically for two-component urethanes. Since two-component urethanes are moisture sensitive, any contact with air can cure the material, locking up the dispense valve. This production proven design eliminates exposure of wetted shafts to air.

Features

  • Uses same manifold and ergonomic handle as standard Series 450 valve.
  • A thicker tie plate increases the distance between the lip seals to be more than the stroke length, resulting in extended seal life and less down time.
  • Divorced air cylinder keeps isocyanate from reaching the air cylinder should the seals fail .


Advantages

  • Easy to Clean: If cross contamination occurs, the manifold can be removed and cleaned without disassembly of the valve body
  • Optional Stainless Steel Valve: Recommended for corrosive acrylics or epoxies
