Item # 7702447, 450XT Snuff Back Valve


EFD meter mix offerings consist of a meter mix dispenser and a static mixer. They set the standard for high-volume, two-component dispensing operations by combining easy, reliable operation with simplified maintenance.

Meter mix valves feature an innovative design that prevents cross-contamination by keeping A and B components separate until they enter the mixer-an approach that reduces downtime by eliminating the need for solvent flushing. When cleaning is required, the modular design permits fast, easy disassembly.

Spiral mixers attach to the dispenser manifold and blend the components into a homogeneous mix that ensures optimal material performance. Mixers are available in different styles and element configurations to accommodate a wide variety of materials and production requirements.

EFD valves are available in a variety of configurations to accommodate different fluids, flow rates, viscosities and volumetric ratios. Two of our newest offerings include the high flow valve and the recirculating valve.

Features and Benefits
  • Dispenses two-component adhesives and sealants
  • Can be mounted for beads or timed shots
  • Manual, robotic or stationary operation
  • Aluminum or stainless steel configurations
Designed specifically for dispensing 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. Optional stainless steel valve is available for corrosive acrylics or epoxies.
