Sealant Equipment & Engineering Inc.'s new 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, oozing or dripping. Pneumatically actuated, the Tip-Seal valve has a carbide tip, titanium-coated shaft, hardened seat and wear-resistant fluid seals to extend valve life. The stroke adjuster can set the needle opening to change material-flow rates and bead-profile sizes.
