The core enquiry checklist
| Information | What to provide |
|---|---|
| Item reference | Your line or tag number, valve type and any specified model. |
| Size & pressure | DN or NPS and the required pressure designation. Include the governing standard; avoid treating PN and Class as interchangeable. |
| Materials & seating | Required body, trim, seat and packing materials, or attach the material specification. |
| Connection & operation | End connection and standard, manual or actuated operation, power supply if applicable. |
| Quantity & timing | Quantity per line, quote deadline and required delivery milestone. |
| Service conditions | Fluid, design and operating conditions, and special inspection or approval requirements. |
If information is missing
Mark it as “to be confirmed” rather than selecting an arbitrary value. A catalogue match is a starting point; final compatibility and ratings must be reviewed against the requirement.
