What Are The Valve Core Structures?

Rotary Valve Core Structure

The rotary valve core is a key component of a valve, controlling fluid flow through rotation. This type of valve core is typically cylindrical or conical, rotating around its axis. Rotary valve cores are simple in structure, easy to operate, and widely used in various fluid control applications.

 

Lift Valve Core Structure

The lift valve core structure controls fluid flow by moving up and down. The valve core is typically cylindrical, driven by an actuator to move up and down, achieving tight contact or separation with the valve seat. This type of valve is suitable for applications requiring precise flow control.

 

Resilient Valve Core Structure

The resilient valve core structure is a more specialized type of valve core. The core is typically made of elastic materials, such as rubber or plastic. When the valve is opened, the resilient valve core deforms to adapt to fluid pressure, achieving fluid regulation. This type of valve has excellent sealing and regulating performance and is widely used in some specialized fluid control applications.

 

Needle Valve Core Structure

The needle valve core structure is a more refined valve structure, with the valve core appearing as a sharp needle. Valves with this structure offer excellent sealing and switching performance, making them suitable for applications requiring precise control of fluid flow and pressure, such as industrial control and laboratory equipment.
