In industrial systems, check valves and ball valves are two common types of valves, and they play important roles in fluid control. However, there are significant differences between these two types of valves in terms of structure, working principle, application scenarios, as well as advantages and disadvantages. This article will conduct a comprehensive comparison between check valves and ball valves in tabular form to help readers better understand their applicable scopes and the pros and cons.

Valves are indispensable components in fluid transportation systems, and their main functions are to control the flow direction, pressure and flow rate of fluids. However, valves will generate certain flow resistance during the working process, which will not only reduce the flow rate of the system but also increase energy consumption. Therefore, optimizing the flow resistance coefficient of valves and improving their flow capacity have important practical significance.
