In response to your needs, Nordson EFD has designed
and manufactured an innovative dispense valve
specically 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.
Weight
• Aluminum Valve and Manifold: 1.6 lbs (0.7 kg)
• Stainless Steel Valve and Manifold: 2.5 lbs (1.1 kg)
Pressure Rating
• 3,500 psi (240 bar)
