Description

Valve actuators on ships are essential components in the control of fluid systems, such as ballast water, fuel oil, fresh water, and seawater systems. They automate the operation of valves, allowing for remote or automatic control, which is crucial for the efficient and safe operation of a vessel. 

Electric Actuators:

  • Motorized Operation: Uses an electric motor to move the valve stem.
  • Remote Control: Can be controlled from a central control room.
  • Types:
    • Rotary: For valves that turn (e.g., ball or butterfly valves).
    • Linear: For valves that move in a straight line (e.g., gate or globe valves)
    • Electric actuators are widely used in marine applications due to their reliability, precision, and ability to be remotely controlled. Here's a detailed overview of electric actuators used on ships:

      Overview of Electric Actuators:

      Electric actuators convert electrical energy into mechanical motion to operate valves. They are highly versatile and can be used for both rotary and linear valve operations.

      Components of Electric Actuators:

      1. Electric Motor:

        • The motor drives the actuator, converting electrical energy into mechanical motion. It can be AC or DC, depending on the application.
      2. Gearbox:

        • Reduces the motor's speed and increases torque, allowing the actuator to handle larger valves with higher force requirements.
      3. Limit Switches:

        • These are used to define the open and closed positions of the valve. They automatically stop the actuator when the valve reaches its designated position.
      4. Position Sensor:

        • Provides feedback on the valve's position, allowing for precise control and monitoring.
      5. Control Circuitry:

        • Handles the commands from the control system, enabling remote or automated operation of the actuator.
      6. Manual Override:

        • Allows manual operation of the valve in case of power failure or emergency.
      7. Enclosure:

        • Protects the internal components from harsh marine environments, often being weatherproof and corrosion-resistant.
