ITT BioViZion fractional hygienic diaphragm valve.
BioViZion brings EnviZion's thermal-compensation and quick-maintenance concepts to fractional 0.25, 0.375, and 0.5 inch valves. It is designed specifically for sampling and other low-flow bioprocess duties where conventional small four-bolt valves can be difficult to assemble and seal consistently.

Selection guideWhere it fits
Use BioViZion for compact sample, drain, and low-flow valve points that need manual or pneumatic operation. Confirm body size and connection, manual versus actuated bonnet, fail mode, diaphragm, pressure, temperature, and washdown or autoclave requirements.

What to verify before selecting.
The right diaphragm valve is not just a size and connection. Body geometry, drainability, actuation, sensing, diaphragm material, and documentation all matter.
| Selection point | Why it matters | Triplex note |
|---|---|---|
| Body geometry | Drainability, deadleg control, and access change by body style. | Start with process path and cleaning requirement. |
| Diaphragm and wetted materials | Chemistry, temperature, and cycle life drive material selection. | Use compatibility review before final selection. |
| Actuation and feedback | Manual, pneumatic, and sensing choices affect automation and maintenance. | Match plant controls and validation expectations. |
