What documentation should be included in a valve RFQ?

State the requested valve datasheet, drawing, material information, inspection and test requirements, certificates, marking, packing, quantity, destination and project schedule before quotation.

Can marine or class documentation be provided for every valve?

Documentation and certification depend on the selected product, project scope, inspection arrangement and availability. Specify the exact requirement before quotation so feasibility can be reviewed.

Why should documentation requirements be confirmed before production?

Early confirmation aligns the valve configuration, inspection scope, documents, lead time and delivery plan with the purchase order and avoids late project changes.

Valve Certification & Export Documentation Guide

For project valve procurement, documentation is part of the technical scope—not an afterthought. Providing the required certificates, drawings, material information and inspection plan at RFQ stage helps align the product configuration, delivery schedule and order documents.

Important: requirements such as class documentation, third-party inspection, test records and material certificates must be specified before quotation. They are reviewed against the selected product and confirmed order scope.

1. Start with the application and valve data

Service conditions

State medium, pressure, temperature, line size, connection standard and installation duty.

Valve configuration

Identify valve type, body and trim material, seat or seal, actuation, control signal and fail action.

Project requirements

Provide drawings, specification, line list, inspection request, vessel/project reference and delivery destination.

2. Typical documentation to clarify

Document or activity	What to confirm before quotation
Datasheet and drawing	Tag number, dimensions, face-to-face, connection, material, actuation and revision requirement.
Material and marking	Required material grade, traceability scope, nameplate language and project marking.
Inspection and testing	Applicable pressure test, functional test, witness or hold point, and inspection party.
Certificates and project documents	Exact requested certificate or class/documentation scope, issuing party and submission timing.
Packing and export delivery	Preservation, packing type, labels, destination, Incoterm and delivery date.

3. Marine and offshore projects

Marine projects commonly require more detailed coordination because the valve must match vessel systems, corrosion conditions, project specifications and document-control procedures. Send the valve schedule or technical specification with the exact documentation request. Jinkon can review the requested scope for the selected valve package before quotation.

4. Avoid common RFQ delays

Do not describe a certificate generically—name the required document, inspection party and project standard.
Include the valve tag, quantity and delivery schedule with the application data.
For actuated valves, add voltage, signal, feedback, control mode and required fail action.
Confirm whether documents are required per order, per batch or per individual valve.
