What is API 6D,API 608,ISO 17292 Full Welded Ball Valve
Fully Welded Ball Valve is a ball valve type with welded, flanged, or threaded connections, available in nominal sizes from NPS 2" to 48" (DN50 to DN1200) and pressure ratings from Class 150 to 2500. It operates within a temperature range of -38°C to 380°C and is constructed with materials such as A105, LF2, F304, and F316. The sealing system features carbon fiber-reinforced PTFE.
The valve adopts a fully forged steel welded body with liquid penetrant inspection of weld grooves. Carbon steel components undergo electroless nickel plating. It is equipped with a mirror-polished stainless steel ball, preloaded spring seats, and a blowout-proof stem design, supporting manual, worm gear, electric, or pneumatic operation.
The double-seat design enables independent fluid cutoff, providing double block and bleed (DBB) functionality. The single-weld structure optimizes manufacturing processes and sealing reliability. The product complies with design standards such as API 608 and API 6D, with end connections meeting ASME B16.5 specifications.
