What are Actuated Valves?

Actuated valves are a type of valve that is controlled by an external power supply, such as electricity or compressed air. They are commonly used in industrial applications where a reliable and precise control of the flow of liquids or gases is necessary. Actuated valves are designed to open and close automatically based on the input they receive from the control system, which can be a computer, a remote control, or a manual switch.

Actuated valves offer several benefits compared to traditional manually operated valves. They provide accurate and reliable control of the flow, prevent leaks, reduce the risk of contamination, and improve the overall efficiency of the system. They also offer remote operation, which saves time and reduces the need for manual labour.

How do Actuated Valves Work?

The main function of an actuated valve is to regulate and control the flow of a fluid or gas. The valve can be opened or closed by a motor, solenoid, or pneumatic actuator. When the valve is open, the fluid or gas can pass through the valve and into the pipeline. When the valve is closed, the fluid or gas is prevented from flowing through the pipeline.

Actuated valves work in a variety of ways, depending on the type of valve and actuator used. For example, a ball valve may be actuated using a motor and the ball is rotated to allow or block the flow of fluid. A butterfly valve may be actuated using a pneumatic actuator and the valve disc is turned to regulate the flow.

Actuated valves can be operated manually or automatically. In manual mode, the operator opens or closes the valve using a handle or lever. In automatic mode, the valve is controlled by a controller, such as a PLC, and a sensor, such as a flow metre or pressure gauge. The controller sends a signal to the actuator to adjust the valve position based on the measured parameter.

Where are Actuated Valves Commonly Used?

Actuated valves are widely used in various industrial sectors, where automated control of fluid or gas flow is required. These valves are commonly used in the oil and gas industry, chemical production plants, water treatment facilities, and power generation plants. Actuated valves are also found in HVAC systems, food and beverage processing plants, and pharmaceutical manufacturing facilities.

The versatility of actuated valves makes them suitable for controlling the flow of various fluids, including steam, oil, water, and chemicals. They are also used for controlling pressure, temperature, and level of fluids.

How to Choose the Right Actuated Valve for Your Application?

When selecting an actuated valve, it is important to consider its design, material construction, and compatibility with the fluid or gas in your system. The valve design must be suitable for the flow direction and fluid pressure in your system. The material construction should be able to withstand corrosion, temperature, and pressure conditions specific to your application.

The type of actuator is also important in selecting the ideal valve. Electric actuators are more suitable for applications that require precise control and positioning, while pneumatic actuators are recommended for applications that require fast opening and closing speed.

What Type of Actuated Valves are Available?

Electrically Actuated Valves

These valves use an electric motor to drive the valve actuator. They are ideal for applications that require precise control, such as in HVAC systems and food processing plants. These valves can be controlled remotely, making them suitable for hard-to-reach areas.

Pneumatically Actuated Valves

These valves use compressed air to operate the valve actuator. They are often used in industrial applications, such as powering pneumatic actuators for pumps and compressors. They are lightweight, easy to install, and require minimal maintenance.

Hydraulically Actuated Valves

These valves are operated via a hydraulic system that operates the valve actuator. They are commonly used in heavy-duty applications that require high pressure and large flow rates, such as in power plants and mining operations. These valves offer excellent reliability and durability, making them ideal for harsh operating conditions.

Solenoid-Actuated Valves

These valves are operated via an electromagnetic coil that moves the valve actuator. They are commonly used in fluid control applications, such as irrigation systems and water treatment plants. These valves are cost-effective, easy to install, and require minimal maintenance.

What are the Advantages and Disadvantages of Using an Actuated Valve?

Advantages of Actuated Valves

Actuated valves offer precise control and fast response times, making them ideal for applications that require quick and accurate adjustments. They also eliminate the need for manual control, which can be time-consuming and labor-intensive. Actuated valves can also be placed in hard-to-reach locations, which can be dangerous for human workers.

Disadvantages of Actuated Valves

One of the main disadvantages of actuated valves is their cost. They are typically more expensive than manual valves due to the added complexity of the actuation mechanism. Actuated valves also require a power source, which can be an issue in remote or hazardous locations. If the power source fails, the valve may not function correctly, which can be a safety hazard.


In conclusion, actuated valves are a game-changer in the world of industrial applications. With their precise control, increased efficiency, and reduced maintenance requirements, they are quickly becoming the go-to choice for many industries. So, if you’re looking to streamline your processes and improve your bottom line, consider making the switch to actuated valves today!
