What is an Automated Globe Valve?
An automated globe valve is a type of valve that utilizes an automated mechanism to control the flow of fluids in piping systems. Characterized by its spherical body shape and internal baffle, this valve design allows for excellent throttling capabilities, making it ideal for applications requiring precise flow regulation. Automated globe valves can be operated using various actuators, including pneumatic, electric, and hydraulic systems, enabling remote and efficient operation in industrial settings.

How Does an Automated Globe Valve Work?
Automated globe valves operate by adjusting the position of a movable disc within the valve body, which varies the flow path. When the actuator receives a control signal, it moves the disc up or down against the flow, allowing for precise control over the volume of fluid passing through. The actuator type—whether pneumatic, electric, or hydraulic—determines how the valve responds to commands, influencing the overall efficiency and speed of operation.

FAQs
How Does an Automated Valve Work?
An automated valve operates using an actuator that responds to control signals, adjusting the valve’s opening or closing position to regulate flow. The type of actuator—pneumatic, electric, or hydraulic—determines how the valve is controlled.
What is the Function of the Automatic Valve?
The function of an automatic valve is to control the flow of fluids within a system, providing the ability to regulate volume, pressure, and flow rates without manual intervention.
How to Actuate a Globe Valve?
To actuate a globe valve, you need to apply the appropriate control signal to the actuator (pneumatic, electric, or hydraulic). This signal will move the actuator, which in turn adjusts the position of the valve disc, enabling precise flow control.
