The BioviZion packs all of the industry leading breakthrough technology of the EnviZion valve platform into a small package developed specifically to address the critical reliability needs of sampling and low flow bioprocess applications.
Traditionally, small 4-bolt fractional size diaphragm valves utilized for sampling applications have been challenged to achieve the performance and reliability of traditional diaphragm valves simply because of dimensional limitations. Four small screws prone to galling just can’t provide the force required to achieve consistent and reliable seat and shell sealing.
Enter the BioviZion with high strength stainless steel studs which eliminate small fasteners prone to galling, snapping, and being lost. The patented diaphragm stud makes diaphragm installation a quick and reliable process. The efficient mechanical thermal compensation system applies sealing force constantly only where it is needed. Best of all no torqueing or re-torquing is required. All of these features add up to a more reliable and less costly valve to operate and maintain.
