Global manufacturer and supplier of conformal coating and precision dispensing systems, PVA (Precision Valve & Automation, Inc.) is pleased to announce the release of the new VPX-2KS dual component spray valve. It is a progressive cavity metering valve, capable of accurately spraying 2K chemistries. A servo controlled rotor that seals a rubberized stator produces a continuous flow of material for each component. The tight tolerance on the sealing mechanism assures pulse- free and drip-free operation of the valve, even with low viscosity fluids. Frank Hart, Sales and Marketing Manager states, “The VPX-2KS dual component spray valve is just another example of how the company continues to meet the growing needs of our customers. We are seeing increased demand in two-component coatings both from end users and in development from formulators. This valve introduces the cleanest, most flexible atomized process for 2K coatings while also providing unparalleled volumetric accuracy.”
The valve requires no routine flushing or purging as each component is metered in a separate chamber. The A and B components are introduced via a disposable static mixer in the air cap to produce a fine conical shaped pattern. The valve features a ± 2 % accuracy, dependent on material with a viscosity range of 1 – 100,000 cps.
