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 710PT-LF 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 710PT-LF 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 710PT-LF valve, pressure pot and controller. The connecting link between reservoir and 710PT-LF 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.
