Needle dispensing valve

sprayvolumetricwide viscosity range

Overview
Absolutely uniform spray patterns, repeatable accuracy and without splashes – the volumetric metering valves from DOPAG make it possible.

Product note
The volumetric spray valves for lubricants are available in two versions: based on the needle metering valve or based on the chamber metering valve.

Versions

• Needle metering valve (0.003 - 0.2 ml)
• Chamber metering valve (0.05 - 3 ml)

Benefits

• Contactless material application with metering accuracy < ±1 %
• Reliable process even without additional monitoring
• Precise and individually adjustable spray patterns
• Broad portfolio of nozzle extensions for maximum flexibility

Spray pattern and nozzle extensions
Compared to conventional spray adapters, DOPAG valves are equipped with an integrated material throttle enabling individually adjustable spray patterns and avoiding splashes. An almost unlimited selection of nozzle extensions is available for accessibility to different shapes and geometries; customised extensions can be provided depending on requirements.

Options

• Various nozzle extensions with different spray cones/directions
• Solenoid valve plate 24 V for control
• Air maintenance unit for spray air
• Stroke detection to increase process reliability

Technical specifications

• Volumetric metering for volumes from 0.003 - 3.00 ml
• Viscosity range 10 to 1,000,000 mPas
• Material inlet pressure max. 150 bar
