Tip-Seal™ Dispense Valve Range

The following air operated Tip-Seal™ valves are for automated application of beads or 'drops' of silicone or moisture sensitive materials.

The double air operated valve allows high flow rates due to a less restrictive internal design.  This increase in flow rate translates into lower supply pump operating pressures, less down time, and reduced maintenance costs.
 

Tip-Seal™ KISS™ valves incorporate a carbide hardened integrated needle and nozzle assembly with an abrasion resistant seal to further increase its life cycle and reduce down time.  Its stainless steel spring ensures an instantaneous shut-off when the valve is closed or if air pressure is lost.  The alignment and mounting holes make fixturing simple; multiple inlet ports allow you to 'gang' valves together to a common material supply source for simultaneous dispensing from multiple valves.
