Main types of valve cores

Conical Valve Core

The conical valve core is the most common type. It has a conical shape and fits tightly with the valve seat to control opening and closing. This type of valve core has a simple structure, is easy to manufacture, and is widely used in various valves.

 

Cylindrical Valve Core

Cylindrical valve cores are mainly used in valves requiring frequent operation. Their cylindrical shape allows them to rotate or move linearly within the valve seat to open and close the valve. This type of valve core is characterized by low operating torque and good sealing performance.

 

Needle Valve Core

The needle valve core is named for its needle-like shape. It is typically used in applications requiring precise flow or pressure control, such as instrument valves. The needle valve core allows for precise adjustment of the valve opening degree, achieving precise control of flow or pressure.

 

Hemispherical Valve Core

The hemispherical valve core is typically used to control the opening and closing of fluid media. Its hemispherical shape allows it to rotate within the valve seat to open and close the valve. This type of valve core has good flow performance and is widely used in various fluid control systems.

 

Valve cores come in various forms, mainly including conical, cylindrical, needle-shaped, and hemispherical shapes. Each type of valve core has its unique characteristics and applications. When selecting a valve core type, it is necessary to choose according to the actual working requirements and scenario to ensure that the valve's performance and usage effect reach the optimal state.
