RFQ Checklist
To reduce mismatch risk, include these details when requesting a quotation:
- Valve name, standard reference, nominal size, pressure class, material, and quantity.
- Photos of the old valve, nameplate or casting mark, flange face, handwheel or actuator, and installed position.
- Application line, such as seawater, bilge, drain, cooling, ballast, fuel, or deck service.

Matching Notes Before Quotation
