ITT PfuZion bonnet conversion for Bio-Tek bodies.
The PfuZion bonnet assembly converts an installed ITT Pure-Flo Bio-Tek fractional body to EnviZion-based quick-connect topworks and diaphragm technology. The retained body keeps its original product-contact material, flow coefficient, and rated seat and shell pressure while the new bonnet adds thermal compensation and faster diaphragm replacement.
What ITT PfuZion bonnet conversion for Bio-Tek bodies is—and where it fits.

The retained body keeps its original product-contact material, flow coefficient, and rated seat and shell pressure while the new bonnet adds thermal compensation and faster diaphragm replacement.
Where it fits
Use it as an upgrade path for eligible 0.25, 0.375, and 0.5 inch Bio-Tek bodies rather than replacing the complete valve. Confirm body identity and condition, conversion size, manual ZMB/ZMBS versus pneumatic ZPB configuration, fail mode, diaphragm, and required validation review.
What to confirm
Confirm the installed Bio-Tek body identity and condition, conversion size, manual or pneumatic topworks, pneumatic fail mode when applicable, diaphragm, process conditions, and validation requirements.
How Triplex helps
Triplex helps keep the actuator conversation tied to the complete valve package so the hardware works in the plant, not just on a datasheet.
What Triplex will want to know.
Good valve recommendations come from process context. A few details up front prevent a lot of expensive back-and-forth later.
| Selection point | Why it matters | Triplex note |
|---|---|---|
| Manual or automated operation | Manual bonnets, pneumatic actuators, and stainless actuator options solve different plant realities. | Confirm who operates the valve and how often it cycles. |
| Fail position and force | Actuator sizing depends on valve size, diaphragm, process pressure, and fail-open/fail-closed expectations. | Do not size the actuator from the actuator name alone. |
| Controls and environment | Feedback, solenoids, washdown exposure, and service access can determine the best topworks package. | Triplex can help coordinate actuator, switch package, and documentation needs. |

Use these documents as a starting point, then confirm final selection against the actual process conditions.
Keep the selection connected to the full ITT valve platform.
