The pinch
tube valve is a compact and cost effective device for dispensing very thin
liquids, semi-viscous materials, cyanoacrylates, anaerobics, solvents, UV cure
adhesives and two-component fluids. For repeat dots, beads or potting of liquids
fed from a syringe, cartridge or pressure pot. The only part of the valve
that makes contact with the liquid is the low cost replaceable
pinch tube assembly. This makes the
TS1212 valve ideal for aggressive or curable liquids with no risk of the
material setting and damaging expensive parts.
Compact and easy to set up,
this valve is operated by any of our valve controllers.
The controller provides a timed pulse of air pressure to open the TS1212 pinch
tube, allowing the adhesive or liquid to flow. A spring loaded shut-off provides
the ability to make micro dots if required with no drips between shots. The shot
size is determined by the time setting on the controller, the fluid pressure, the amount of opening
set on the adjustable stroke control and the size of needle tip used. For
complete systems, we offer a range of options
including TS1212 valve, pressure pot and controller. The
connecting link between reservoir and TS1212 is a
fluid line that offer a safe luer lock
connection and are suitable for use with most liquids and adhesives. Use
Teflon lined or Teflon tips for
cyanoacrylates, General Purpose tips for other fluids and
Tapered tips for viscous liquids.
Low cost replacement pinch tubes are
available from stock in clear or black. These systems require a simple compressed air
feed. The liquid is pressurised to the valve. This flow is regulated
on the pressure pot. Using needle tips, you can provide a high level
of control over the deposit size.
