Flour - Model API 6D - Ball Valves Brochure

FLV Ball valve, along with the butterfly valve and plug valve, are part of the family of quarter-turn valves. FLV Ball valve has a spherical design device with a hole in it used for isolation and on-and-off service. The ball is always in the fluid path. Because this valve is symmetrical, either end can be the inlet allowing flow to come through either direction, and can be used for changing flow direction. Unlike other valves, the Ball valve may have different designs, but they are all assembled the same way. Ball valves have many configurations: floating, trunnion mounted, union body, split body, end entry, top entry, 3-piece, etc. There are also special service designs: cryogenic, metal to metal, subsea, severe conditions, double block, and bleed.
