Needle Valves dispense very precise deposits over a wide range of shot
and bead sizes due to a minimal dead fluid zone. An external stroke
control adjustment to fine-tune shot sizes. Easy to maintain, with little or
no downtime. The compact design and easy-mount threaded hole allows
for easy integration into automated applications.
The TS5420 Adjustable Needle Valve is a pneumatically triggered singleacting
valve that can be used with an integral spring close (single action)
or may be connected for air closing without the spring (double acting).
The TS5440 Microshot Needle Valve, with its needle closing the fluid path
directly on the cannula inside the dispensing tip hub, can dispense very
precise deposits down to 0.0005 cm3.
• Precise and consistent shot sizes
• Adjustable flow control
• Zero dead fluid zone
• Simple and low maintenance design
To dispense microdots of low viscosity fluids such as: solvents, inks, oils,
activators, primers; the TS5440 is excellent to dispense microdots of UV
adhesive used in medical device manufacturing.
