Disposable Pinch Tube Valves provide control for continuous or micro shot applications of low to semi-viscous fluids. The TS1212 semi-automatic version relies on a dispensing controller sending a pre-programmed air signal that opens the valve and allows fluid to flow. Once the dispense cycle is complete, the air signal stops and the internal spring forces the shut-off piston to "pinch" the disposable feed path, preventing further fluid flow. 

The only part of the valve making contact with the fluid being dispensed is the disposable pinch tube assembly making the TS1212 ideally suited to dispensing 2-part and CA (Cyanoacrylate) materials. 

Recommended Controller: TS500R, TS350, TS250 in conjunction with TS1258
