Techcon TS5540 Spray Valve, 0.028 In Round Cap SS

Description

The Techcon TS5540 is a precision dispensing valve built for spraying low-viscosity adhesives, conformal coatings, and lubricants in a controlled pattern rather than a bead. FDA-compliant 303 stainless steel forms the air cylinder and fluid housing, and this configuration ships with the 0.028 in round orifice cap for a tight, circular spray footprint. An external stroke control lets the operator fine-tune fluid flow at the valve instead of adjusting fluid pressure at the pump, which keeps setup changes fast on a line running more than one part.

Where This Dispensing Valve Fits

• Conformal coating lines applying low-viscosity fluids over PCB assemblies
• Fine mist or fan spray lubrication on small mechanical assemblies
• Surface treatment and primer spray ahead of a bonding or coating step
• Automated dispensing cells where the valve mounts to a robot or gantry head

Dispensing Valve Specifications

• Orifice: 0.028 in, round cap pattern
• Housing and cylinder material: 303 stainless steel, FDA-compliant
• Seat: field-replaceable Delrin seat for positive shutoff and long cycle life
• Control: external stroke adjustment for fine fluid-flow tuning
• Best suited to: low-viscosity adhesives, coatings, and lubricants (not heavy-bodied sealants)

Pair this dispensing valve with the matching TS5540 fan cap (0.046 in) if the line needs to switch between a tight round pattern and a wider fan pattern without swapping the whole valve body. Techcon supplies fluid tubing, needle adapters, and controller connections sized to the TS5540 platform, so confirm compatible fittings before the valve goes on the line. Cycle rate and shot size both depend on the air pressure feeding the cylinder, so start at the manufacturer’s recommended pressure and adjust the external stroke control from there rather than compensating with fluid pressure alone. Most shops run this valve on fluids in the low-hundreds-of-centipoise range; heavier fluids call for a larger orifice or a different valve family entirely.
