Techcon Air Cap Round 0.028 Orifice, Stainless Steel

Description

The Techcon Air Cap Round 0.028 Orifice is a stainless steel dispensing valve parts component built for the TS5520 and TS5540 spray valve platforms used across automated adhesive, sealant, and coating lines. It threads onto the valve body in place of the standard cap and directs air and fluid through a fixed 0.028 in (0.711 mm) round orifice, producing a cone-pattern spray suited to fine coating passes and edge sealing where a fan pattern would overspray the target area.

Where dispensing valve parts like this fit

Spray valve systems built around the TS5520 and TS5540 wear at the nozzle and cap first, since that is where atomized fluid and compressed air meet the part surface. Swapping the cap for a fresh, correctly sized 0.028 orifice keeps the cone spray pattern consistent instead of drifting wide or thin as the original orifice wears. Shops running conformal coating, light lubrication, or thin sealant lines on a fixed spray station use this cap to standardize coverage across a full production run without adjusting the controller’s pressure setting mid-shift. Low to medium viscosity fluids in the 1 to 1,000 cps range, including UV cure conformal coatings, light oils, and thin solvent-based sealants, run cleanly through the 0.028 in round orifice at the valve’s normal activation pressure.

Materials and fit

• Orifice diameter: 0.028 in (0.711 mm), round (cone) pattern
• Material: 303 stainless steel
• Valve compatibility: Techcon TS5520 and TS5540 spray valve series
• Mounting: threads directly onto the spray valve nozzle body
• Max fluid pressure: rated to the valve’s 100 psi (6.9 bar) system limit
• Activation pressure: 70 psi (4.8 bar) minimum, per TS5540 spec

Ordering these dispensing valve parts

Stock a spare cap alongside the matching nozzle outlet kit so a worn orifice does not stop a production line waiting on a single part. A spray pattern that has gone ragged at the edges or started to drift off-center is usually the orifice wearing oversize rather than a controller or fluid problem, and swapping the cap resolves it faster than troubleshooting pressure settings. The 0.028 in size sits between the 0.014 in fine-mist option and the 0.046 in high-flow option in the TS5520/TS5540 nozzle lineup, and it is not interchangeable with the fan-pattern versions of the same orifice size.
