Catalog excerpts

With meter, mix and dispense systems, the pneumatic Series 450 Autovalve is a durable and reliable valve. In addition, the seals can be adjusted without disassembly of the valve body. The pneumatic Series 450 Autovalve is similar to the Series 400 Autovalve, except for the shut-off pistons which ensure good control of dot or shot volume. After each shot, the dual pistons retract and "snuff back" material from the end of the mixing nozzle. This feature helps eliminate "after drool." This valve includes hard-coated and lubricated pistons. It can be used either as a stationary head or hand-held unit. Features  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  Flush Valve Manifold: For cleaning the mixing nozzle with air or solvent. A check valve is threaded into the side of the manifold  Lubricated and Hard Coated Pistons: Lubricated with Nordson EFD Autogrease for moisture sensitive adhesives and hard-coated to resist abrasive adhesives  Optional Polytuff, PTFE, Viton® and EP Seals: For varying chemical formulations and abrasive conditions  Optional Night Cap Ratio Check Cap: Available for 1:1 ratio manifold Speciﬁcation  Weight (Al Valve and Manifold): 1.6 lbs (0.7 kg)  Weight (SS Valve and Manifold): 2.5 lbs (1.1 kg)  Pressure Rating: 3
