How Many Types of Actuator Valves Are There

Time: 28-September 2025 | Source: I-FLOW| Share

Actuator valves are an essential part of modern fluid control systems, enabling automatic or semi-automatic operation. They combine a valve with an actuator, allowing precise control of flow, pressure, and direction without manual intervention. But how many types of actuator valves exist, and how do they differ?

  1. Manual Actuated Valves

    • Operated by a handwheel, lever, or gear.

    • Simple, cost-effective, but limited to non-automated systems.

  2. Pneumatic Actuated Valves

    • Powered by compressed air.

    • Known for fast response and safe use in explosive environments.

    • Common in process industries like food, chemical, and water treatment.


  3. Electric Actuated Valves

    • Driven by an electric motor.

    • Ideal for applications needing precise flow control.

    • Used in HVAC, power plants, and automated industrial pipelines.

  4. Hydraulic Actuated Valves

    • Powered by pressurized fluids.

    • Offer high force and reliability in heavy-duty systems.

    • Widely used in oil & gas, marine, and high-pressure applications.


Key Considerations When Choosing

  • Operating environment (explosive, high-pressure, cleanroom).

  • Power source availability.

  • Required precision and speed.

  • Maintenance and cost factors.
