What is a variable orifice used for in a process?

A variable orifice is a device used in various industrial applications, primarily for controlling the flow rate of a process fluid. This component can adjust its opening size, allowing operators to regulate the volume of fluid passing through a system based on specific requirements, such as changes in pressure or flow demand. By manipulating the size of the orifice, it can achieve the desired flow characteristics, which is essential in maintaining process efficiency and ensuring that conditions remain within specified limits.

The ability to adjust flow dynamically is crucial for optimizing processes, enhancing safety, and ensuring that production conditions are met. Therefore, its primary function focuses on the regulation of flow rather than measurement, temperature control, or filtration, which are associated with other types of devices in industrial systems.
