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.
The Spool Valves provide precise shot accuracy along with “high volume”
capacity over a range of material viscosities, shot sizes and pressures.
They feature “suck back” anti-drip as well as a fast on/off dispensing
function that is not affected by material input pressure. An optional oil
chamber creates an additional liquid seal to prevent moisture from being
carried on the spool, excellent for moisture sensitive materials.
Pneumatically activated, the valves can be used with an internal spring
close (single acting) or an air-closing connection (double acting).
Output is a 1/4" NPT which allows multiple types of tips to be used.
The TS9200D Jet Tech is a non-contact dispense valve capable of jetting fluid viscosities to 400,000 Cps. Jet Tech offers a fast jetting action producing hundreds of precise droplets in less than one second.
The main feature of the valve is a single, easily replaceable diaphragm to eliminate dynamic fluid seals found in other jet valves. No longer is it necessary to disassemble, clean and replace worn seals, which translates into saving time and money. The diaphragm also allows fast cycle rates because of its very small mass. There is no large sliding valve stem that slows down the process. With this novel diaphragm design, the energy needed to eject a drop can be adjusted providing a wider process window.
The TS9200D Series Jet Tech is available in the following configurations:
• TS9200D-125E Jet Valve EPDM Diaphragm, 125µm Nozzle
