The Operation Theory of Electric Globe Control Valves
- Valve Body: This is the main structure of the valve housing all the internal components. It typically consists of a globe-shaped chamber with inlet and outlet ports, as well as a movable disk or plug that controls the flow.
- Actuator: In electric globe control valves, the actuator is an electrical component responsible for moving the valve’s closure member (disk or plug) to adjust the flow rate. The actuator receives signals from a control system or operator and converts them into mechanical motion to open or close the valve.
- Closure Member: This is the part of the valve that regulates the flow by either obstructing or allowing passage through the valve body. In globe valves, the closure member is typically a disk or plug that moves perpendicular to the flow direction. By positioning the closure member, the flow rate can be controlled.
- Positioner (Optional): In some electric globe control valve setups, a positioner may be used to precisely control the position of the closure member based on feedback from sensors. The positioner ensures accurate positioning of the closure member according to the control signal received by the actuator.
- Control System: The control system provides the input signals to the actuator, which in turn adjusts the position of the closure member based on the desired flow rate or process conditions. The control system can be manual, pneumatic, or electronic, depending on the application requirements.
- Feedback Mechanism: In advanced systems, feedback mechanisms such as position sensors may be incorporated to provide real-time information about the position of the closure member. This feedback helps the control system to maintain precise control over the flow rate and respond to changes in process conditions.
