Auto-Flo Dispensing Valves
Automatic cut-off fluid dispense valve for automotive industry
Nordson automatic on/off dispense valves provide accurate deposition and control for applications requiring sharp material cut-off, as well as uniform beads and spray patterns. These valves are designed to handle a wide range of high performance, high-viscosity adhesives and sealants, including RTV silicones, grease, mastics, plastisols, epoxies, weldable sealers, urethanes and weldable/expandable sealers.
Nordson dispense valves are available with operating pressures up to 5,000 psi, and are capable of dispensing materials with viscosities up to 3,000,000 cps. Refer to the application chart in this literature to determine which valve best meets your specific material application requirements.
Features
• Air-actuated open/spring closed feature assures full flow in all applications.
• Spring-closed with air-closed option prevents leaking under high pressures.
• Precision mounting for end-of-arm robot tooling with precisely positioned dowel pins assure correct distance from the valve to the part, minimizing robot reprogramming.
Auto-Flo Module
• Replaceable seal cartridges allow for easy maintenance and repair of valves.

Auto-Flo Zero Cavity Valves
Nordson zero cavity valves provide accurate deposition and flow control for applications requiring clog-free operation, sharp cut-off and uniform bead patterns. Zero cavity valves feature a close-tolerance matched needle-and-seat assembly that eliminates the formation of minute material pockets. This design provides a self-cleaning action, preventing material blockages that can cause tails and adhesive stringing.
Anti-Drool Valve
Nordson anti-drool valves are designed for positive on/off flow control, reducing the need for clean-up and rework due to material drips and run-on between beads and shots. The anti-drool valve features…
Anti-Drool Valve
Nordson anti-drool valves are designed for positive on/off flow control, reducing the need for clean-up and rework due to material drips and run-on between beads and shots. The anti-drool valve features a negative pressure cut-off to ensure clean, drip-free application, even with low-viscosity materials.
- Recommended for dispensing high-viscosity
- RTV silicones, grease, mastics, plastisols, epoxies and weldable sealers.
- Negative pressure cut-off reduces drips, tails and stringing.
- Air open/air closed operation assures full flow with positive cut-off and prevents leakage under high pressure.
CE20 Valve
- Recommended for dispensing extremely viscous materials including urethanes and weldable/ expandable sealants up to 3,000,000 cps.
- Air-actuated open/air closed feature assures full flow…
CE20 Valve
- Recommended for dispensing extremely viscous materials including urethanes and weldable/ expandable sealants up to 3,000,000 cps.
- Air-actuated open/air closed feature assures full flow in high-pressure applications.
- Durable high-pressure/high flow design with tapered needle and seat for better flow control and cleaner cut-off at higher pressures.
- Replaceable seal bonnet contains all seals for faster, easier maintenance, and reduced downtime.
- Precision mounting for end-of-arm robot tooling.
- In-line inlet/outlet port configuration prevents unwanted pressure drop, assuring consistent and accurate material deposition.
