A ball valve is a device with a spherical closure unit that provides on/off control of flow. The sphere has a port, also known as a bore, through the center. When the position of the valve is such that the bore is aligned in the same direction as the pipeline, it is in open position and fluid can flow through it. The bore becomes perpendicular to the flow path when rotated 90 degrees which means the valve is closed and the fluid cannot pass through. The ball valve along with butterfly and plug valves is part of the quarter-turn valve family. Ball valves are known for reliable, bubble-tight sealing, thus they are a great choice for gas application where tight shutoff is necessary. Ball valves are not ideal for throttling applications due to the potential of constant wear on the seats. A ball valve’s body is usually made of steel and can be made more durable with nickel plating.
The most common ball valves are considered to be two-way, which allows flow to travel linearly from the inlet to the exit. Furthermore, the three-way and four-way ball valves allow for flow to travel in multiple directions, including 90-degree angles. Mainly there are four general body styles of ball valves which are fully welded, three-piece body, split body, and top entry. The difference is based on how the pieces of the valve are manufactured and assembled, but the operation of the valve is all the same in each type. Each design has its own benefits, like the fully welded ball valve gives it maximum strength at minimum weight, as well as maximum resistance, both to pipeline pressures and stresses. The compact and spherical design also eliminates body flanges, thus reducing the overall size and leak paths.
A ball valve is a shut-off valve controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotation of the ball by a quarter turn around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life span, even when the valve is not in use for a long time.
Ball valves are a Quarter Turn Shut Off valves available in Brass, Bronze, Lead-Free Beass, Cast Iron and Stainless steel Material. Types of Ball Valves available are 1Pce, 2 Pce, 3 Pce and are also available in Full Port or Reduced Port. A typical application would be Commercial, industrial and residential applications
