RF Flanged Ball Valves
RF Flanged Ball Valves are used for raised-face flanged process and pipeline connections where bolted maintenance access is preferred. Use this specification range to match the requirement to the correct ball valve construction, seat system, material combination, end connection and project testing scope.
RF Flanged Ball Valves: what to confirm before quotation.
RF Flanged Ball Valves are grouped by connection rather than by a single valve construction. The correct valve can be floating, trunnion mounted, top entry, fully welded or DBB depending on the service.
End connection changes installation and maintenance
A RF flanged ball valve must be coordinated with piping class, pressure rating, wall thickness or flange standard, face-to-face requirements and site welding or bolting practices. The valve construction and end connection should be selected together.
Raised Face Ball Valve for project piping
Flanged ends support bolted removal, while welded ends reduce flange joints and can suit high-integrity pipeline service. Higher pressure or buried service can change the preferred connection and inspection requirements.
RFQ data for RF flanged ball valve
Send the applicable valve and piping specifications together with service medium, design pressure and temperature, line size, valve class, materials, end connection, operation and inspection requirements. This allows the manufacturer to avoid assumptions that can cause technical deviations later.
Match this specification to the valve construction.
This specification does not define the complete valve. Compare the requirement with the product designs below before RFQ.
RF Flanged Ball Valves FAQ
What valve designs are available as a RF flanged ball valve?
Depending on the project, the requirement can be combined with floating, trunnion mounted, top entry, fully welded or double block and bleed valve construction.
What information is needed to quote a RF flanged ball valve?
Provide valve type, size, pressure class, material requirements, end connection, design pressure and temperature, media, operation, test requirements and the applicable project specifications.
Is raised face ball valve a separate valve design?
It combines the named specification with a valve construction or application. The final design still depends on the complete datasheet.
