Split butterfly valves (SBVs) consist of two halves that dock together, an active (Alpha) unit and the passive (Beta) unit. Each unit houses half of the butterfly disc, which is sealed against the main body with an elastomeric seat to create high containment seal. This minimises the amount of airborne particle exposure during the transfer of potent powders from one process step to the next.
PPE manufactures custom designed valve seats in a range of high performance, USP Class VI compliant, elastomer materials. Perlast perfluoroelastomers (FFKM) provide the ultimate chemical resistance and are able to withstand the most aggressive cleaning regimes.
