Full Welded Body Ball Valve

Supported by a team of skilled and experienced professionals, we manufacture and export a wide array of Full Welded Body Ball Valve.

Full Welded Body Ball Valves typical application is for gas transmission, buried pipelines (underground), larger sizes (up to 60 inches) and medium pressure classes (up to ASME 900 psi). Raw material can be either forgings or centrifugal castings. Wide range of materials: A105,LF2,F304,F316,F304L,F316L,F51,WCB,WCC,CF8,CF8M,CF3,CF3M,A890 4A etc

Technical features: anti blow-out stem and valve seats design available in three different versions:
* SPE (Single Piston Effect): the seat is energized by upstream pressure only .
* DPE (Double Piston Effect): the seat can be energized by upstream pressure or by body cavity pressure.
* DUAL (SPE upstream and DPE downstream): combining the two seat designs explained above, a double barrier can be assured in case of seat sealing failure.

Product details:
Standard design :API 6D / API 6D SS / ASME B16.34/ISO 17292.
Valve ends: Flange, Butt-Welding
Fire Safe standard: BS6755 / API 6FA / API 607( since each sealing point is provided by a secondary fire-safe seal in graphite. Valve soft seats also are provided with secondary metal-to-metal seal in case of fire.)
