Purged pulse diaphragm valve Patent pending

The first purged diaphragm valve was introduced over a decade ago. Despite it offering a variety of benefits, the technology’s main disadvantage was that a separate purged flow path was necessary. This meant integration costs, carrier flow consumption costs and manufacturing complexity. Our pulse purge diaphragm valve (PPDV) changed all that. Using the static purge principle to purge the valve’s inner volume through the actuation gas, it works for applications that require the features of a diaphragm valve as well as when better performance is needed from existing applications without design changes.
