3. Valve Body This is the main structure of the valve through which the fluid flows. It contains the inlet and outlet ports.

4. Valve Trim The trim consists of internal components like the valve plug, seat, and other parts that control the flow of fluid through the valve. It's designed to regulate the flow rate and pressure.

5. Actuator The actuator is responsible for moving the valve trim to adjust the flow of fluid. It can be pneumatic, hydraulic, or electric, depending on the application.

6. Positioner T here's a positioner attached to the actuator. It ensures that the valve is opening or closing to the exact position required for the desired flow rate.

7. Position Feedback This component provides feedback to the control system about the current position of the valve. It helps in maintaining precise control over the process.

8. Bonnet and Packing The bonnet covers the valve body and provides a seal to prevent leakage. Packing, usually made of materials like PTFE, surrounds the valve stem to prevent fluid from leaking out around the stem.
