Size classification of ball valves

1. Classification according to caliber
Ball valve is a kind of valve widely used in pipeline and equipment systems, and its diameter is a key indicator to evaluate the size of ball valve. Generally speaking, the caliber of the ball valve is divided according to the diameter of the ball. Common ball valve diameters include DN15, DN25, DN50, DN100, etc. By referring to different standards and specifications, you can understand the distinguishing standards of different calibers in ball valves, and select the appropriate caliber ball valves according to your needs.
2. Classification according to structural materials
The structure and material of the ball valve also have a certain influence on the division of its size. Depending on the structure and material of the ball valve, the ball valve can be divided into various types. For example, the material of the spherical structure can be plastic, cast iron, stainless steel, copper, forged steel, etc.; The connection methods include flange connection, threaded connection, etc. Ball valves of different structures and materials can be used for different mediums, pressures and other occasions, and choosing the appropriate structure and material of ball valves can better meet the needs of use.
3. Classification according to the use pressure
In addition, the operating pressure of the ball valve is also one of the important bases for classifying its size. The operating pressure generally refers to the working pressure range of the ball valve, which indicates the maximum pressure value that the ball valve can withstand under normal working conditions. Depending on the pressure used, ball valves can be divided into low, medium and high pressure ball valves. Low-pressure ball valves rely on seals and springs to achieve sealing purposes, and are suitable for media with low working pressure
