New valves for fine liquid coatings
The TS5520 Spray Valve was developed to enable customers to apply fine mist liquid coatings onto any substrate, controlling deposit sizes by varying the dispensing height above the substrate
OK International has launched the TS5520 Spray Valve, developed to enable customers to apply fine mist liquid coatings onto any substrate, controlling deposit sizes by varying the dispensing height above the substrate Small dots can be applied by positioning the valve 25.4mm above the surface, while heights up to 304.8mm can be used to coat an entire board

Easy transition to lead-free soldering
OK International announces a series of enhancements that optimise existing Metcal MX-500 and SP200 systems for a simple, cost-effective transition to lead-free soldering
The DX-200 series of digital dispenser/controllers
The DX-200 series of digital dispenser/controllers offer affordable and highly accurate and repeatable micro-air digital dispensing systems
A short opening stroke provides an extremely fast and positive shut-off, while external variation of the stroke control makes it easy for the operator to fine-tune the spray output.
A wide range of adjustments can be made to vary the dispensing spray size down to a very fine mist.
The TS5520 includes a pneumatically triggered single acting valve, and there is a separate air path to ensure full atomisation of the sprayed material and a highly consistent spray pattern.
OK International will also introduce two new Techcon Systems Stainless Steel Valves.
The TS5540 and the TS5540F valves spray a fine mist of low-viscosity materials such as conformal coating, solvent, oil and grease precisely and consistently for thin-film fluid deposits.
Both valves come with a variety of nozzle/cap configurations for spraying different fluid deposit patterns and sizes.
The TS5540 has three cone-shaped nozzles/caps, for spraying three sizes of circular-shaped deposits.
The TS5540F With three fan-shaped nozzles/caps The TS5540F is for spraying three sizes of elliptical-shaped deposits.
Both valves have a 70 psi (4.8 bar) activation pressure and handle fluid pressure at a maximum of 100 psi (6.9 bar).
Apart from having different size and shape nozzle/cap, TS5540 and TS5540F are identical in their main valve body build.
The TS5540 and TS5540F have a smooth fluid path that reduces turbulent flow and air entrapment ensuring consistent, precise and repeatable spraying.
In addition, they feature an external stroke control that adjusts for different fluid flow and provides an extremely fast, positive shut-off.
