Techcon TS5420SS Precision Needle Valve, Stainless Steel

Description

The Techcon TS5420SS is a stainless steel precision needle dispensing valve for controlled deposits of low to medium viscosity fluids. It is built for automated or benchtop dispense stations that need small dots, clean beads, and fast shut-off with materials such as adhesives, oils, sealants, inks, and light greases. The stainless wetted path makes this version a good fit when the fluid or cleaning routine calls for a more durable body than an aluminum or plastic valve can provide.

Where this dispensing valve fits

The TS5420SS belongs in production cells where repeatability matters more than hand-applied speed. It can place very small deposits, then close quickly with an internal spring return so the next cycle starts from a controlled position. External stroke adjustment lets a technician tune shot size at the valve instead of rebuilding the fixture. That matters on electronics, medical device, appliance, automotive, and general assembly jobs where one station may need a short dot for one part and a longer bead for the next.

The valve works well when the process uses a pressure reservoir, controller, and fixed dispense tip to remove operator variation from the shot. It can sit on a bench fixture, a shuttle table, or an automated head, and the small body size helps leave room for cameras, clamps, part nests, and other tooling around the dispense point. Maintenance teams also like this family because the wear parts are accessible, so a scheduled service can restore shut-off behavior without replacing the entire station.

How the dispensing valve holds accuracy

The TS5420SS uses a 1/8 in NPT female fluid inlet and male Luer lock outlet, so it can pair with common feed lines, tips, and nozzles in a Techcon system. The mounting port helps fixture builders lock the body into a bracket or end-of-arm tool without a custom clamp. When paired with the correct controller and reservoir, the valve can cycle at high speed while keeping the fluid path compact and serviceable.

It is rated for fluid pressure up to 300 psi and covers a broad viscosity range from 1 to 100,000 cps. Wetted materials include stainless steel, Teflon, EPR, and Delrin, which gives the valve practical compatibility across many industrial fluids while still requiring a final material check before production release.
