Latest addition to ITT's extensive EnviZion valve product line

ITT Inc.’s Engineered Valves brand is proud to announce the latest addition to the extensive EnviZion valve product line. The new BioviZion fractional size valve includes the breakthrough technology of the EnviZion valve platform in a compact package for 1/4-1/2” applications, with features that provide a more reliable and less costly valve to operate and maintain.

“The unique EnviZion design has set a new standard for valves in the BioPharm industry,” said Dave Loula, Global Product Director for ITT Engineered Valves. “We have incorporated the same patented technology into a fractional size valve and added new features to overcome challenges related to dimensional limitations. This provides manufacturers with improved performance and reliablility for critical sampling and low flow installations.”

Key features

  • Mechanical thermal compensation system. A sealing force is constantly applied to prevent external leaking over a range of temperature changes.
  • Quick change bonnet. Maintenance of the valve is reduced by 10 times compared to conventional valves.
  • High strength stainless steel studs. Small fasteners, prone to galling, breaking, and misplacement, have been eliminated.
  • Patented diaphragm stud. Diaphragm installation is a simple, quick and reliable process that can be completed in approximately three minutes.

The EnviZion valve platform offers a more streamlined installation and maintenance process, delivering less downtime, longer preventative maintenance cycles and greater production capacity for manufacturers. Assembled with a simple mount and turn motion, the EnviZion valve is maintained in approximately three minutes without using any special tools or difficult torquing procedures. The valve’s 360° active seal protection provides leak-free operation, helping eliminate the risk of contamination and the need to re-torque after thermal cycling.

Product Description

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.
