Techcon TS934A Aluminum Spool Valve, 1/4 in Inlet

Description

The Techcon TS934A dispensing valve is an aluminum high-pressure spool valve with a 1/4 in inlet for controlled adhesive, sealant, paste, and resin dispensing. The balanced spool design opens and closes quickly, so material flow can start and stop cleanly without being driven by changes in material input pressure. It fits production cells that need repeatable deposits from pressure pots, cartridges, or pumped feed systems.

Where this dispensing valve fits

Use the TS934A where a manual or automated station handles viscous materials and needs a positive shutoff at the valve. The aluminum body keeps the assembly lighter than a stainless configuration, while the 1/4 in fluid path suits larger beads and higher volume shots. It belongs with dispensers, mixers, and nozzles used in bonding, gasketing, encapsulating, and assembly work.

How the dispensing valve controls flow

The spool moves forward when air pressure is applied, opening the path from the inlet to the outlet. When air pressure is relieved, the return spring pulls the spool closed and stops flow. The spool action also draws a small amount of material back during shutoff, creating an anti-drip effect at the nozzle. An oil chamber above the upper seal provides an added liquid barrier that helps protect the spool area during service.

Specs

Select this valve for systems where shutoff speed, pressure-independent response, and clean nozzle breakoff matter more than manual control alone. Pair it with compatible tips, lines, fittings, and controllers sized for the material viscosity and bead profile. For Techcon product family context, visit Techcon.
