Valve Ball

Image provided by Victaulic

A ball valve uses a ball as the opening/closing device and operates with a one-quarter (90°) turn similar to the plug valve. The ball seals by fitting tightly against resilient seat rings on either side. Flow is straight through, and pressure loss depends on the size of the opening in the ball (port). Ball valves are generally selected for on/off service, but can be used as balancing valves. They are easily adapted to power actuation and are generally less expensive than equivalent sizes of gate and globe valves. Ball valves have three port sizes: standard, reduced, and full port. Standard port is gener-ally one pipe size smaller than the valve size, reduced port is up to two sizes smaller, and full port has the same opening as the connecting pipe.

Ball valves are available in a variety of body types. A one-piece body, also called an end entry, is machined from solid bar stock material or is a one-piece casting. The ball is inserted into one end for assembly, and a body insert that acts as a seat ring is threaded against the ball. A two-piece body, also an end entry design, is the same as a one-piece valve except that the body insert is larger and acts as an end bushing. The three-piece body consists of a center body section containing the ball that fits between two body end pieces. The entire assembly is held together by two or more body bolts. The three-piece body design allows the valve to be repaired without disassembling surrounding piping.
