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. |
