Automatic Dispense Valves High-performance automatic dispense valves provide uniform material deposition and excellent flow control for precise, consistent material application. Features and Benefits All Nordson automatic dispense valves incorporate the following features: ir-actuated open/spring closed feature assures A 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. 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. Auto-Flo™ Valve The Nordson Auto-Flo valve is recommended for applications requiring high-pressure dispensing at high flow rates. Specially designed with a large ball-and-seat, the Auto-Flo is capable of handling pressures up to 5,000 psi. Recommended for dispensing high-viscosity RTV and weldable sealers. Large ball-and-seat design for improved material flow. Dispenses material in a uniform bead or kiss.

Automatic Dispense Valves For more 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 closetolerance matched needle-andseat assembly that eliminates the formation of minute material pockets. This design provides a self-cleaning action, preventing material blockages that can cause tails and Zero Cavity Valve adhesive stringing. Nordson zero cavity valves include: – Stand-alone or manifold mount configurations – 3mm or 4mm orifices...
