What is the Difference between the Pneumatic Actuated Valves and Electric Actuated Valves?

Valves are essential components in various industrial applications, controlling the flow of fluids and gases. Among the most commonly used types are pneumatic actuated valves and electric actuated valves. Understanding the differences between these two can help in selecting the right valve for specific applications. This article provides a detailed comparison of pneumatic and electric actuated valves, highlighting their key features, advantages, and disadvantages.

Pneumatic actuated valves are operated using compressed air. They are widely used in industries where air supply is readily available and where quick, reliable actuation is required. Pneumatic actuated valves are known for their durability and ability to operate in harsh environments.

Electric actuated valves, on the other hand, are powered by electric motors. They are commonly used in applications where precise control and automation are necessary. Electric actuated valves are known for their accuracy and ease of integration with control systems.

The 3 Main Differences between Pneumatic Actuated Valves and Electric Actuated Valves

Different Driving Mechanisms

  • Pneumatic Actuated Valves: These use compressed air as the power source. They open and close the valve through a pneumatic actuator.
  • Electric Actuated Valves: These use a motor as the power source. They open and close the valve through an electric actuator.

Different Operating Characteristics

  • Pneumatic Actuated Valves: They have a high torque and fast switching speed, respond quickly, and have a simple structure that is easy to maintain. However, they require a stable air supply and have a more complex control system.
  • Electric Actuated Valves: They have a lower torque and slower switching speed. They do not require an air supply and have a simpler control system.

Different Suitable Applications

  • Pneumatic Actuated Valves: These are ideal for environments requiring high explosion-proof and safety reliability, such as chemical plants and flammable or explosive environments. They are relatively low-cost and easy to maintain.
  • Electric Actuated Valves: These are suitable for general industrial environments where explosion-proof requirements are not high and there are no hazardous conditions. They are more costly and less suitable for humid environments.

For controlling large-diameter pipelines with liquid media, electric actuated valves are more effective. Pneumatic actuated valves are more efficient in controlling small-diameter pipelines with gas media.


Both pneumatic and electric actuated valves have their unique advantages and are suited to different applications. Pneumatic actuated valves are ideal for environments requiring fast, durable, and fail-safe operations, while electric actuated valves are preferred for applications needing precise control and quiet operation.
