Understanding Actuated Valves: Definition, Types, and Applications

What Is Actuated Valve

In the intricate world of industrial processes, where the control of fluids and gases is important, actuated valves stand as choices for precision and reliability. But what exactly are these remarkable components that effortlessly manage the flow of vital media within the hidden veins of our manufacturing, chemical industries, oil and gas? So, what is an actuated valve?

Actuated valves are the ingenious answer to this question, providing an automated touch of finesse to the essential task of controlling flow. In this exploration, we will unveil the secrets of actuated valves, uncovering their significance, types, and applications and revealing how they shape the foundation of countless industrial operations.

What Is an Actuated Valve?

Actuated valves, an integral part of numerous industrial processes, play a pivotal role in regulating the flow of fluids and gasses. These valves, equipped with automated control mechanisms, enable precise and efficient management of the media they handle. 

In essence, an actuated valve is a valve that incorporates an actuator, typically an electric, pneumatic, or hydraulic mechanism, to control the valve’s position. This intelligent automation empowers industries to fine-tune their processes, ensuring safety, accuracy, and reliability.

Actuated valves find applications in a wide array of industries, including manufacturing, oil and gas, chemical processing, and many more. They are favored for maintaining consistent flow control, regardless of external factors.

Types of Actuated Valves

Actuated valves come in numerous configurations to cater to diverse industrial requirements. Each type is designed with specific features to address particular needs. Here, we’ll explore some of the most common types of actuated valves, providing you with insights into their distinct characteristics.

1. Handwheels Fixed to Stem

Handwheel-actuated valves are a simple yet effective choice when manual adjustments are sufficient. These valves feature a handwheel connected to the stem, allowing operators to turn the wheel to open or close the valve manually. 

Handwheels provide tactile feedback, enabling operators to make precise adjustments. This actuated valve type is commonly used when automation is not essential and human intervention is convenient. They are found in applications like isolation valves, where occasional adjustments are needed.

2. Solenoid-Actuated Valves

Solenoid-actuated valves are electrically operated. They rely on a solenoid to open or close the valve, making them highly responsive and suitable for applications that require rapid changes in fluid flow. They are often used in automated systems and remote control applications.

3. Hydraulic-Actuated Valves

Hydraulic-actuated valves are powered by hydraulic systems, which use pressurized fluids to control valve movement. These valves are favored in applications that demand significant force, as hydraulic systems can provide substantial power. 

Heavy machinery, construction equipment, and large-scale industrial processes often rely on hydraulic-actuated valves to ensure precise and reliable control. The high force capabilities make them invaluable for tasks such as heavy lifting, equipment positioning, and controlling hydraulic circuits.

4. Spring-Actuated Valves

Spring-actuated valves are designed to close automatically when there is no external force applied. These valves use a spring mechanism to ensure that the valve is in the closed position when it’s not actively being controlled. 

This feature makes them highly suitable for fail-safe applications, where maintaining a closed valve is critical in emergencies or power failures. Spring-actuated valves are commonly found in safety systems, such as emergency shut-off systems in gas pipelines, where immediate closure is imperative in hazardous situations.

5. Manual-Actuated Valves

Manual-actuated valves are simple and cost-effective, relying on human intervention to adjust the valve’s position. These valves are suitable for low-tech applications where automation is not required.

6. Self-Actuated Valves

Self-actuated valves utilize the process fluid’s pressure to control their position. These valves are often used in applications where maintaining a constant pressure or temperature is critical, such as in steam systems.

7. Electric-Actuated Valves

Electric-actuated valves are equipped with an electric motor or actuator, offering precise and automated control. They are versatile and widely used in applications where accuracy and consistency are vital. 

Electric actuators respond to electrical signals, allowing for fine-tuned adjustments in a wide range of processes. Industries that require precise control over fluid or gas flow, such as food and beverage, pharmaceuticals, and water treatment, often rely on electric-actuated valves.

8. Pneumatic-Actuated Valves

Pneumatic-actuated valves rely on compressed air to control valve position. They are known for their quick response and are commonly used in industries where the presence of compressed air systems is prevalent.

Working Principle of Actuated Valves

The working principle of actuated valves is relatively straightforward. These valves are designed to open and close based on the input from their actuator. The specific mechanism of operation, whether electric, hydraulic, pneumatic, or manual, determines how the valve functions. 

Actuators convert energy into mechanical motion, ultimately influencing the valve’s position. In the case of electric actuators, the energy is electrical, while hydraulic actuators use pressurized fluids, and pneumatic actuators rely on compressed air.

The key to the successful operation of actuated valves is precision. They are engineered to respond to control signals with great accuracy, ensuring that the fluid or gas flow is precisely regulated. This accuracy is vital in industrial applications where consistency and safety are paramount.

To learn more about the working principles of actuated valves, it’s essential to consult with experienced professionals or refer to specific product manuals for detailed insights.
