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 the TS1212 is a fluid line that offers a safe luer lock connection and is 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. Please note the stand is ordered separately and is not included.

The TS1212 requires no regular maintenance other than the possible replacement of the valve rubber seat inside the main body. This is a low cost replacement part. One of the benefits of this valve is that the pinch tubes are replaceable to eliminate the need of maintenance.

Typical Applications Pinch valves are used for many varied assembly and production processes where controlled deposits of low to medium viscosity liquids need to be applied. Common applications include:- Dots and beads of Cyanoacrylates Dots and beads of solvents Dots and beads of epoxies Dots and beads of UV cure Dots and beads of PVA glues Potting of components Deposits of liquid fluxes Dots and beads of threadlockers General adhesive application
