ITT Pure-Flo 913 stainless-steel manual bonnet.
The 913 is a stainless-steel handwheel bonnet for Pure-Flo valves, available in standard 913 and sealed 913S versions. It combines manual operation with an adjustable travel stop, position indication, hygienic internals, and optional secondary containment for critical washdown or product-containment applications.

Where it fits
Choose it where manual operation, corrosion resistance, or a sealed topworks is required. Confirm valve size, pressure, diaphragm, 913 versus 913S, washdown chemistry, lock or opening-stop options, and autoclave requirements.
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. |
