What is an Electric Actuated Valve?

An electric actuated valve is a pivotal component in modern industrial processes, offering precise control over the flow of fluids through pipelines. These valves are operated by an electric actuator, which converts electrical energy into mechanical torque, facilitating the opening or closing of the valve. This automation capability is crucial for industries requiring exact flow regulation, such as water treatment, chemical manufacturing, and HVAC systems. Fluid-Air Components, with its extensive experience in providing high-quality valve solutions, stands at the forefront of supplying electric actuated valves that enhance operational efficiency and reliability.

The versatility and efficiency of electric actuated valves make them an indispensable part of industrial operations, ensuring processes run smoothly and efficiently. In the following sections, we will delve into the design and operation of these actuators, highlighting how their torque and breakaway torque, response time, control methods, and voltage requirements contribute to their overall functionality.

Firstly, we’ll explore the design and operational aspects of electric valve actuators, beginning with torque and breakaway torque, to understand how these elements influence the performance of electric actuated valves.

Understanding Electric Valve Actuators

Design and Operation

The core of an electric actuated valve’s functionality lies in its design and operational mechanics, which are tailored to meet the demands of diverse industrial applications.  

Torque and Breakaway Torque

Torque is the force that the actuator applies to turn the valve, while breakaway torque refers to the initial force required to overcome the static friction and begin movement. These parameters are critical in selecting the right actuator, as they must match the valve’s specifications to ensure efficient operation without overloading the system. Fluid-Air Components meticulously assesses these factors, providing actuators that offer the precise torque needed for the smooth operation of valves in any setting.

Response Time

Response time is another crucial aspect, defining how quickly an actuator can move the valve from open to closed position or vice versa. This is particularly important in applications where rapid adjustments to flow are necessary. Fluid-Air Components’ understands the importance of swift response times, enhancing process control and reducing downtime in critical operations.

Control Methods

Electric valve actuators can be controlled in various ways, including local controls, remote signals, or through automated process control systems. This versatility allows for integration into a wide range of industrial systems. Fluid-Air Components provides actuators with flexible control options, ensuring compatibility with the specific requirements of each application, whether it involves simple on-off operations or sophisticated modulation.

Voltage Requirements

The voltage requirements of an actuator must be compatible with the available power supply in the installation environment. Actuators come in different voltage configurations to accommodate standard industrial power supplies. Fluid-Air Components offers a wide range of electric actuators designed to operate efficiently across different voltage levels, ensuring seamless integration into existing infrastructure.

As we delve into the features of electric valve actuators in the next section, we will uncover how position indicators, manual override capabilities, limit switches, duty cycle, fail-safe features, and modulation capabilities further enhance the functionality and reliability of electric actuated valves.

Features of Electric Valve Actuators

Electric valve actuators are equipped with a range of features that enhance their functionality, reliability, and ease of use. These features not only contribute to the precise control of fluid flow but also ensure the safety and efficiency of industrial processes. Fluid-Air Components, recognising the importance of these features, ensures that their range of electric actuators is designed to meet the high standards required by diverse industrial applications.

Position Indicators

Position indicators are essential for providing visual feedback on the valve’s status, whether open, closed, or somewhere in between. This feature is crucial for operators to monitor and verify the operation of the system at a glance, thereby facilitating quick decision-making and troubleshooting. Fluid-Air Components’ actuators include clear and accessible position indicators, supporting effective process management.

Manual Override

Manual override is a critical feature that allows operators to control the valve manually in the event of a power failure or when electronic control systems are unavailable. This ensures that essential flow adjustments can be made, maintaining operational continuity even under unforeseen circumstances. The manual override function also acts as an added layer of operational security.

Limit Switches

Limit switches play a pivotal role in electric valve actuators by signalling the actuator to stop once the valve has reached its fully open or fully closed position. This prevents over-torquing, which could damage the valve or actuator. Fluid-Air Components incorporate robust limit switches into their actuators, ensuring precise control and longevity of the valve system.

Duty Cycle and Fail-safe Features

The duty cycle of an actuator defines how long it can operate without overheating and needing to cool down. Electric actuators with a high duty cycle are suited for applications requiring frequent operation. Additionally, fail-safe features, such as the ability to return the valve to a safe position on power or signal failure, are vital for maintaining safety in critical systems. Fluid-Air Components offers actuators with optimised duty cycles and fail-safe options to match the operational demands of various industries.

Modulation Capabilities

Modulation capabilities allow for the precise control of valve positioning, facilitating the accurate regulation of fluid flow. This is essential in applications where flow conditions need to be adjusted continuously. Fluid-Air Components’ electric actuators are capable of sophisticated modulation, ensuring precise control over the flow rates, which is crucial for process optimisation and efficiency.

In the next section, we will discuss how to select the right electric valve actuator, taking into consideration the specific needs of an application and the criteria that influence the selection process. This will include insights into application considerations and selection criteria that ensure the chosen actuator aligns perfectly with the operational requirements.

Selecting the Right Electric Valve Actuator
