Application guide - high pressure gasket beads of silicone and sealants


Customers applying gasketing materials or similar, require a precision dispense valve system to provide control and accuracy when making these beads of viscous silicones, sealants, RTVs, etc. High pressure feed system from large ram driven pail pump.

Solution to use a TS941 spool valve fed by customers own pail pump and controlled by a TS350 digital controller unit. Material is fed under very high pressure to the valve (max 2500 psi) 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.


System supplied with a selection of components including fluid lines connectors, tips, tubes, caps and fittings. Supplied with universal power supply, airline connection kit, foot pedal, valve mounting bracket, user guide, etc. Ready to use out of the box.

Parts used: TS941 spool valve, TS350 digital controller, TTN16 smooth flow tapered tips, TSD931-7 tip adapter, 7015LLBPK tip cap, (customers own pail pump).
