ITT Pure-Flo Advantage Series 33 actuator.
The Series 33 extends the Advantage pneumatic actuator range to 3- and 4-inch (DN80-100) Pure-Flo valves in a reduced-size package. It is available fail-close, fail-open, or double-acting and was designed to reduce installation envelope and weight compared with the older large-valve Series 47 arrangement.

Where it fits
Use Series 33 for compatible large Pure-Flo valves where actuator size and weight matter. Confirm valve size, diaphragm, line and shutoff pressure, plant air pressure, fail mode, spring package, temperature, orientation, and support requirements.
What to confirm
Confirm the compatible valve body and size, diaphragm, line pressure, available plant air, fail mode, required shutoff pressure, process temperature, cycle duty, controls, and accessories.
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. |
