The ball valve can be closed tightly with only 90-degree rotation and a small rotating torque. The completely equal inner cavity of the valve body provides a direct flow channel with little resistance for the medium. Generally speaking, the ball valve is most suitable for direct opening and closing, but the recent development has designed the ball valve to make it have the function of throttling and controlling flow. The main feature of ball valve is its compact structure and easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with bad working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integral or combined.
Although there are numerous parts making up the valve the basic components are made up of the following:
Also referred to as the valve housing or shell, it contains all the inner components of the valve. Usually composed of a rigid metal, in this case Stainless Steel, it protects all the internal components and keeps them in the correct position and aligned for proper functioning. It also facilitated access for the external handle to connect with and rotate the internal ball, via the stem. The valve body comes in three assembly options: one-piece, two piece and three-piece designs.
This is the part that gave the valve its name. It is a ball that has "flow path" known as a bore, through the center that allows the medium to flow through it. The ball is rotated by the stem, which either opens the flow when the bore is in-line with the pipe or closes the flow when the bore is perpendicular to the flow. There are two types of bore design: Full port and Reduced port.
Also referred to as the shaft, it connects the external handle that rotates the inner ball. The Stem has washers and packing rings to ensure a tight seal and to prevent any leaks. The stem is rotated as the handle is turned, which in turn rotates the ball, opening and closing the flow.
The Seat sits between the ball and the valve body and ensures a water tight seal. There are two seats that sit on either side of the ball and are usually composed of (PTFE).
The handle is also often called the lever. it a standard ball valve it is the manual way used to turn the ball valve to the open or closed position.
