A butterfly valve RFQ contains a lot of shorthand. Missing one field — like the seat material or end connection — can mean the wrong valve arrives. Here is the checklist we recommend every buyer use.
The 9 Fields Every RFQ Should Have
- Size — DN or inch (e.g. DN200 or 8")
- Pressure rating — PN10/PN16 or Class 150/300
- End connection — wafer, lug or flanged
- Body material — ductile iron, carbon steel or stainless
- Disc material — same or different from body
- Seat material — EPDM, NBR, PTFE or metal
- Medium and temperature — water, oil, gas, steam; min/max temp
- Actuation — manual, pneumatic or electric
- Testing and certification — shell/seat test, material certificates
Common Mistakes on RFQs
Missing end connection is the most common error — wafer vs lug changes both price and whether the valve can do dead-end service. Confusing PN and Class is second: PN16 is roughly Class 150 but not exactly. Forgetting the medium means the wrong seat gets quoted.
What to Attach to Every RFQ
Include: a piping spec or data sheet, the governing standard (API 609 / AWWA C504 / EN 593), and the number of units per size. With those, a supplier can quote accurately on the first round.
