While sanitary diaphragm valves are well suited to a variety of applications, many manufacturers ignore the inherent difference in quality standards of the biotech industry by offering an industrial valve that is simply re-branded as “aseptic” or “hygienic”. When you compare the value of product lost due to contamination in the biotech industry to almost any other field, the need for a sanitary diaphragm valve developed specifically for these high purity applications becomes clear.
This is to update you about a serious concern. We have recently learned of the efforts of third parties to manufacture, distribute and/or sell diaphragms that imitate those of Aquasyn LLC. Such imitation diaphragms are not authorized by Aquasyn LLC.
