DV-09 Needle Valve
The DV-09 is an air-operated, adjustable needle valve
The DV-09 is designed to apply precise, repeatable deposits from a fraction of a microliter up to continuous stripes of low to high viscosity fluids. Specially designed, spring-loaded fluoropolymer needle packings compensate for wear and significantly reduce maintenance downtime. Since the needle shutoff is at the dispensing tip adapter, there is little fluid dead volume in the valve. The positive cutoff action results in a clean and sharp fluid shutoff.
The amount of fluid that flows through the DV-09 valve is determined by the valve open time, fluid pressure, flow control adjustment, dispense tip diameter and fluid viscosity.
- Ideal for low-viscosity fluids used for gasketing or very thin lines
- Needle shutoff provides an even bead at the end of a dispensed line
- Adjustable fluid control
- Low maintenance
- Fast response
- Zero fluid dead volume
- Positive shutoff
- Cycle rate is 500+ per minute
- Compatible with all Nordson ASYMTEK dispensing systems
