In response to your needs, Nordson EFD has designed and
manufactured an innovative dispense valve specically 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)
