A ‘solid’ ball is machined from 100% compact casting or forgeing. The opposite is a ‘hollow ball’ where the ball is constructed with an inside hollow, usually by two metal spheric halves joined together, with or without inside walls or ribs as reinforcement.
The hollow-ball concept is used to save weight and/or money in materials and machining.
If there is a choice between solid and hollow ball for the same application, the solid ball is normally considered as the ‘best cost/lifetime’ solution. Reasons given are less risk for construction, wear, material and fabrication failure over time. The difference between the two could however be from ‘practically insignificant’ to ‘very high’, all depending on quality, QA for product and application circumstances. Note: for some very large constructions solid ball would not be practical.

L-pattern valve balls have flow paths shaped like a capital L , L flow patterns, sometimes called 90-degree balls, are most often used to allow flow from one common inlet port out into one of two different outlet ports. This is why L-pattern flow three-way ball valves are often called diverter valves.

The floating ball valve only has upper stem and the ball can have a slight displacement, so it is called floating ball valve. As the ball is floating, so under the pressure of the medium, the floating ball will move and against the downstream seat., so the seal of the floating ball valve belongs to the single-side seal.The sealing of it is realized by the pressure of the medium,when the ball valve is closed, the floating ball is pressed against the sealing surface under the action of pressure to realize sealing

A V-Port Ball has a ‘v’ shaped tunnel, which allows the orifice to be opened and closed in a more controlled manner with a closer to linear flow characteristic. This type of valve is also known as a control valve, whereby the flow velocities need to be controlled as required per the application.
When the valve is in the closed position and opening is commenced the small end of the ‘v’ is opened first, allowing stable flow control during this stage. This type of design requires a generally more robust construction due to higher velocities of the fluids, which might damage a standard valve.
