Adding another option of customization to its Venturi valve product line, Triatek now offers Kynar® coatings for Venturi valves. No other single manufacturer of Venturi valves offers the level of customization that Triatek does.
Heresite® has long been regarded as the standard for ensuring corrosion protection in ductwork that carries the most harmful and destructive acids and solvents.
However, for some installations, not even Heresite® can prevent the decay that can be caused by some especially corrosive reagents. For these highly critical environments, Triatek recommends using Kynar®-coated valves. Kynar® (or polyvinylidene fluoride) offers superior protection for a broader range of reagents when compared to Heresite®.
A side-by-side chemical resistance comparison chart of Kynar® and Heresite® can be found here. While this information will provide a general sense as to which coating should be used, Triatek still recommends customers test the coating fully for their unique applications.
