Techcon TS5540 Spray Valve Nozzle Assembly, 0.028-Inch Orifice

Description

The Techcon TS5540 spray valve depends on a precisely sized nozzle to control fluid pattern, flow rate, and pressure, and this 0.028-inch orifice nozzle assembly is the genuine Techcon replacement part for that job. If your current dispensing needle has worn down, developed a ragged spray pattern, or started dripping between cycles, this assembly restores the valve to factory spray coverage without the cost of a new valve body. Chemical Concepts stocks this part for production and assembly lines running Techcon spray valve systems on conformal coatings, lubricants, mold release agents, and other low-viscosity fluids.

Built for the TS5540 Spray Valve

This nozzle assembly is sized specifically for the Techcon TS5540, a precision spray valve designed for fluids that need a controlled fan or spray pattern rather than a bead or dot. The 0.028-inch orifice sits toward the middle of Techcon’s sizing range for this valve, wide enough to keep flow workable on slightly thicker fluids while still holding a tight, even spray fan at typical line air pressures. Techcon also offers this same assembly in a 0.014-inch orifice for finer, lower-volume spray patterns.

Signs Your Dispensing Needle Needs Replacing

Nozzle wear on a spray valve usually shows up before the valve body itself fails. Watch for an inconsistent or feathered spray fan, dripping or stringing between cycles, a pattern that drifts off center, or a noticeable drop in coverage width at the same air pressure setting. Because the orifice is a wear item that sees constant fluid and air flow, most shops running TS5540 valves in continuous production keep a spare nozzle assembly on the shelf rather than waiting for a mid-shift failure to shut down a line.

Installation and Fit Notes

Swapping this assembly is a straightforward maintenance task. Most technicians can complete the change with a wrench in a few minutes, without disassembling the valve body or recalibrating the controller beyond a quick spray pattern check at normal operating pressure. Part A0100491 is built specifically for the TS5540 spray valve and is not interchangeable with Techcon’s other precision valve series, jet valves, or the 400 and 700 Series syringe barrel product lines. Confirm your valve model number before ordering, since Techcon’s nozzle and orifice sizing is not standardized across its full valve lineup.

Dispensing Needle and Nozzle FAQ

Is this the same as a needle tip? Techcon calls this a nozzle assembly, but it does the same job as the dispensing needle on other valve platforms: it shapes and directs the fluid stream as it leaves the valve.

Can I use the 0.014-inch version instead? Only if your process calls for a narrower spray fan and lower flow rate. Check your validated process parameters before switching orifice sizes, since coating thickness and coverage repeatability are tied to the original spec.
