Start with the information available
A good request for quotation (RFQ) helps a supplier understand the service, identify sourcing options and state the offered configuration clearly. Do not delay an enquiry just because one technical field is unknown; share what you have and mark anything that needs confirmation.
Valve RFQ checklist
- Valve type: ball, butterfly, gate, globe, check, control, plug, knife gate or actuated valve.
- Size and quantity: nominal size or DN, plus the number of units or line items.
- Pressure and temperature: design or operating conditions and any stated pressure class / PN.
- Service: fluid or media, corrosion concerns, solids content and relevant operating conditions.
- Materials: body, trim, seat and seal materials when specified by the project.
- Connections: flanged, wafer, lug, threaded, socket-weld or butt-weld; include the required standard if known.
- Operation: handwheel, lever, gearbox, pneumatic actuator or electric actuator, including controls when relevant.
- Standards and documents: applicable design standard, inspection or test scope, certificates and project documentation actually required.
- Delivery: destination, required date, packing needs and any project or tender reference.
If you do not have the full datasheet
Send a BOQ, line list, existing datasheet, clear product photo, nameplate photo or a short description of the application. For a replacement, include visible markings and connection details where available. Do not assume a replacement is interchangeable solely because its size looks similar.
Important: this checklist helps organise an enquiry; it does not establish suitability by itself. The offered manufacturer, model, specifications, testing and documents should be checked and confirmed in writing for the actual order.
