450 Series Autovalve
The Series 450 meter mix autovalve features shut-off pistons, which provide precise control of dot or shot volume. Adjust its seals without disassembly of the valve body for added convenience
Overview
The autovalve's dual pistons retract and "snuff back" material from the end of the mixing nozzle, eliminating drool after each shot. Use this durable, reliable pneumatic autovalve as a stationary head or hand-held unit. The valve includes both hard-coated and lubricated pistons.
Valve, manifold, and handle must be ordered for complete assembly. For high back pressure conditions over 1,000 psi (69 bar), order a double air cylinder.
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
Other Available Options
Series 450 XT Snuff Back Valve
In response to consumer demand, Nordson EFD also offers an innovative dispense valve specifically for moisture sensitive, two-component urethanes. Any contact with air can cure two-component urethanes, locking up the dispense valve. The 450 XT’s production-proven design eliminates air exposure of wetted shafts.
