Pure-Flo diaphragm valves for cleanable high-purity process lines.
Pure-Flo is the established ITT diaphragm valve platform for high-purity and sanitary processes where body geometry, diaphragms, actuation, and documentation need to line up with plant standards.
When should you specify an ITT Pure-Flo diaphragm valve?
Quick answer: Specify ITT Pure-Flo when a high-purity or hygienic process needs cleanable isolation, sampling, routing, tank-bottom drainage, or specialty body geometry with the diaphragm as the wetted sealing element. Final selection should combine body style, diaphragm material, bonnet or actuator, controls, end connections, and documentation requirements.
| Application signal | Likely direction | Triplex next step |
|---|---|---|
| High-purity shutoff, sampling, or process isolation | Pure-Flo diaphragm valve | Build the body, diaphragm, bonnet/actuator, and documentation as one package. |
| Existing Pure-Flo tag, body, or diaphragm issue | Replacement or rebuild review | Send tag, size, body style, diaphragm, actuator, and photos if available. |
| New validated or hygienic process point | Application-specific valve assembly | Confirm drainability, materials, controls, documentation, and spare-parts expectations. |
Build the valve conversation around the process risk.
Triplex helps match ITT valve bodies, bonnets, actuators, diaphragms, instrumentation, and documentation expectations to the real process: product, cleaning chemistry, sterilization, pressure/temperature, access, validation, and maintenance.
Body stylesChoose the right body
The process path, drainability, and sampling needs determine which body style belongs in the quote.
Wetted partsDiaphragm review
Chemistry, temperature, and cycle requirements drive diaphragm material review.
AutomationActuation options
Manual and actuated configurations need to fit the plant's control and maintenance expectations.
What to verify before selecting.
The right diaphragm valve is not just a size and connection. Body geometry, drainability, actuation, sensing, diaphragm material, and documentation all matter.
| Selection point | Why it matters | Triplex note |
|---|---|---|
| Body geometry | Drainability, deadleg control, and access change by body style. | Start with process path and cleaning requirement. |
| Diaphragm and wetted materials | Chemistry, temperature, and cycle life drive material selection. | Use compatibility review before final selection. |
| Actuation and feedback | Manual, pneumatic, and sensing choices affect automation and maintenance. | Match plant controls and validation expectations. |

What is an ITT Pure-Flo diaphragm valve used for?
Pure-Flo diaphragm valves are used in high-purity, sanitary, and hygienic process lines where cleanable isolation, body geometry, wetted diaphragm material, and documentation matter.
What parts of the Pure-Flo valve package need to be selected?
The body style, diaphragm material, bonnet or actuator, controls, end connections, documentation, and spare parts should be reviewed together so the assembly fits the process.
What should I send Triplex for a Pure-Flo valve quote?
Send the valve duty, size, end connections, body style, product, temperature, pressure, cleaning/sterilization method, diaphragm material, actuation preference, controls needs, tag numbers, and documentation requirements.
Need help specifying ITT diaphragm valves?
Send the product, process conditions, cleaning/sterilization method, valve size, end connections, actuation preference, and documentation needs. Triplex will help narrow the correct path.
