Application guide - gasketing beads of silicones and sealants form in place

Customers applying gasketing materials or form in place or similar, require a precision dispense valve system to provide control and accuracy when making these beads of viscous silicones, sealants, RTVs, etc.

Solution to use a TS5322 mini spool valve fed by a TS918-110 cartridge reservoir system and controlled by a TS350 digital controller unit. Material is fed under pressure to the valve which is opened by the TS350 either by foot pedal or as part of an assembly machine when connected to a PLC. This system will ensure fast and controlled gasket beads are made without mess, waste or gaps. The valve piston shuts off against the flow and therefore creates a suck-back action to eliminate oozing and mess. If the gasket material is to be fed by a high pressure pail pump, the solution is to use a TS941 spool valve, TS350 controller.

The valve is compact and therefore easily positioned above, to the side or below the work piece. For multiple valve installations, a manifold is used. Stroke adjustment on each valve can be used to fine tune the accuracy. These valves can run a high speed repeatable deposits or on continuous flow.
