A flow control valve limits or regulates the flow of liquids, gases, or mixtures. They can be a standalone component or work in conjunction with a flow or pressure meter. The types of flow-control valves differ in construction and function. Here is an overview of the most common types. First, learn more about how these devices work. After you understand how they work, you can choose the right one for your application.
Flow-control valves limit or regulate the flow of liquids, gases, or a mixture of both:
The valves are devices used to control the flow of liquids, gases, or mixtures. They have different functions and are commonly used to manage the flow of liquids, gases, or a mixture of both. The diameter of the opening of the valve is the amount of fluid that can pass through it and its pressure.
Flow-control valves are used in many applications where the flow of fluids or gases must be controlled precisely. They can be standalone devices or integral components of mass flow controllers. Many of these devices have a feedback loop to adjust the volumetric flow. With these valves, the flow rate can be regulated precisely based on the volumetric flow rate measurement.
One type of liquid-gating gas valve uses a capillary-stabilized liquid to control gas flow. This liquid-gate system offers flexibility and safety in the regulation of gas flow. In addition, its inherent corrosion-resistant property allows it to be used as a safe gas-flow control valve. These valves are essential for many processes, including gas mining, fermentation, multiphase separation, and robots.
They can be a separate component used in combination with a flow- or pressure-meter:
Flow-control valves can be used as a standalone component or conjunction with a flow or pressure meter. Some have a built-in indicator that signals when the valve is open or closed. Other valves can be combined with a separate flow meter or a level transmitter. Regardless of the method, valves are vital for ensuring that your process is running smoothly.
These valves have a two-port design. These valves may be closed to prevent fluid from passing through, completely open to allow maximum flow, or partially open to prevent any flow at all. Most valves have two ports but can be equipped with as many as twenty. Some are designed to regulate different flow levels; these are known as regulating or throttling valves.
They can be made of a variety of materials:
The different types of materials used in flow control valves are important considerations. Stainless steel, for example, is the best choice for valves that have to withstand corrosive media. It is also highly durable and has high temperature and pressure resistance. However, it is more expensive than bronze or cast iron. If your flow control valves must handle corrosive media, you should consider non-sparking materials like nickel, chromium, and copper. Also, you should consider the temperature and pressure limitations of elastomers.
