Basic definition of valve core

The valve core is a crucial component of a valve, located inside the valve body, and plays a key role in controlling the flow of fluid through the valve.

 

The valve core is the moving part of the valve, typically mating with the valve seat, used to open, close, or regulate fluid flow. It controls the fluid by changing the cross-sectional area of ​​the fluid passage through movement, rotation, or other means.

 

The valve core is a vital component of a valve; its performance and quality directly affect the valve's effectiveness and lifespan. Therefore, when selecting and using valves, it is necessary to choose the appropriate valve core type and material based on actual needs and fluid characteristics.
