ITT BioViZion manual bonnet.
The BioViZion manual bonnet is the handwheel topworks for 0.25, 0.375, and 0.5 inch BioViZion sampling and low-flow valves. High-strength studs, a quick diaphragm connection, and mechanical thermal compensation replace the small torque-sensitive fasteners used on conventional fractional diaphragm valves.
What ITT BioViZion manual bonnet is—and where it fits.
The BioViZion manual bonnet is the handwheel topworks for 0.25, 0.375, and 0.5 inch BioViZion sampling and low-flow valves. High-strength studs, a quick diaphragm connection, and mechanical thermal compensation replace the small torque-sensitive fasteners used on conventional fractional diaphragm valves.
Where it fits
Use it for manually operated BioViZion sample, drain, or low-flow points. Confirm body size and connection, diaphragm, BV ZH versus sealed ZHS construction, pressure, temperature, washdown or autoclave duty, travel stop, and operator access.
What to confirm
Confirm the compatible valve body and size, diaphragm and compressor connection, pressure and temperature, washdown or autoclave conditions, sealed-bonnet or travel-stop options, and operator access.
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. |
