Body construction versus end connection
A fully welded body typically uses a permanently joined pressure-containing shell. Butt weld refers to how the valve is connected to piping. These are distinct specifications and should not create duplicate SEO product pages.
Pipeline application
Pipeline projects may require full bore, specific design standards, buried installation features, locking arrangements, stem extensions and corrosion protection. Validate each against the project datasheet.
Buried service details
For buried installation, define extension length, grease lines where required, vent and drain accessibility, stem sealing and external coating. Avoid presenting all fully welded models as automatically suitable for burial.
Documents for procurement
RFQ materials should include line class, nominal size, temperature range, required ends, bore, medium, applicable standard, buried or aboveground service and inspection documents.
Frequently asked questions
Is a fully welded valve the same as a butt weld ball valve?
No. Fully welded describes the valve pressure-shell construction; butt weld describes the pipeline end connection.
Are all fully welded valves suitable for buried installation?
No. A buried-service configuration should be confirmed for stem extension, coating and maintenance access.
