The model 2200-245-125 Tip-Seal dispense valve is designed for precision dispensing of low- to high-viscosity flowable materials. It is also used in high-speed stitching or repetitive on-off applications where short segments of material are deposited onto a surface. The unique Tip-Seal design is ideal for dispensing solvent-based, moisture-curing and stringy materials such as silicones or polyurethanes. The valve opens and closes its material passage at the tip of the nozzle to precisely start and stop material flow. Sealing at the tip also prevents material from hardening in the nozzle, oozing, or dripping.
