Control Valve

Valvesonly is the leading Control valve manufacturer in USA. A control valve is an important part in industrial processes that is designed to regulate the flow of fluid (such as liquids, gases, or steam) through a pipeline. It plays a key role in maintaining the desired process conditions by adjusting the flow rate based on signals from a control system. The physical appearance of a control valve typically consists of a valve body, actuator, and a positioner. The valve body is the main housing that contains the mechanism responsible for controlling the flow. The actuator is the component that receives signals from the control system and translates them into mechanical movement to adjust the valve’s position. The positioner fine-tunes the valve’s position based on feedback, ensuring precise control.

The working principle of a control valve involves responding to signals from a process control system. When the system detects a deviation from the desired setpoint, it sends a signal to the control valve actuator, instructing it to either open or close the valve. This action alters the flow of the fluid, thus influencing the process parameters.
