ITT Pure-Flo Advantage 2.1 pneumatic actuator.
Advantage 2.1 is ITT's diaphragm-operated pneumatic topworks for automated Pure-Flo valves from 0.5-2 inches (DN15-50). Its modular compressor lets compatible PTFE and elastomer diaphragms be changed without disassembling the actuator, while the floating tube-nut design distributes closing force across the diaphragm.

Where it fits
Use it for automated on/off service with fail-close, fail-open, or double-acting operation. Final selection requires valve size, line pressure, available air pressure, fail mode, diaphragm, shutoff requirement, temperature, accessory load, and cycle duty.
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. |
