Circuits Assembly Online Magazine - Sealant Offers Tip-Seal High-Volume Dispense Valve

Model 2600-035 Tip-Seal valve for precision dispensing of medium- to high-viscosity adhesive and sealant materials opens and closes the material passage at the tip of the nozzle to precisely start and stop material flow, and prevent oozing and dripping. Combined with positive-displacement meters delivers precise shot volumes and exact bead profiles.

Use with materials that air dry or cure, such as silicones or polyurethanes. Sealing at the valve's tip prevents material from hardening in the nozzle. Can be used in high-speed stitching or repetitive on-off applications where short segments of material are deposited onto a surface.

Material is delivered to the valve by a metering assembly or under regulated pressure from supply tanks or pumps. The dispense rate can be altered during the dispense process to provide a variety of bead-profile sizes and material-flow rates.

Pneumatically actuated, the valve has large fluid inlet and outlet ports and wear-resistant fluid seals to extend its life. The valve's body slots and precision dowel holes allow easy and accurate mounting.
