Size and Dimension Confirmation
For ANSI valves, dimensions vary by valve type, pressure class, end connection and operation method. Final dimensions should be confirmed by drawing before order.
What to Confirm
Use the size and class information as a selection guide, then confirm detailed dimensions with the project requirement or replacement sample.
- Nominal size: 2"-36" depending on valve type.
- Pressure class: 150, 300, 600, 900, 1500 or 2500.
- End connection: RF, RTJ or BW affects face-to-face and connection dimensions.
- Operation: handwheel, gear or actuator changes top clearance and installation space.
| Dimension Item | Quotation Use | Final Check |
|---|---|---|
| Face-to-face / end-to-end | Preliminary replacement check | Confirm by drawing and applicable ASME/API standard |
| Flange standard | RF / RTJ connection selection | Confirm ASME B16.5 class, facing and bolt details |
| BW end preparation | Pipeline welding connection | Confirm ASME B16.25 and pipe schedule |
| Overall height | Installation clearance planning | Confirm handwheel, gear or actuator arrangement |
| Weight and packing size | Freight estimate | Confirm after model, material and quantity are fixed |
