Electric Actuated Valve

As an Electric Actuated Valve Manufacturer in Canada, Valves Only Canada supplies electric actuated valves for industrial pipelines, process systems and automated flow control. These assemblies use an electric actuator to open, close or position a valve remotely, reducing the need for manual operation.

The suitable configuration depends on the process fluid, operating conditions, valve function, power supply and control system.

What Is an Electric Actuated Valve?

An electric actuated valve combines a valve body with a motor-driven actuator. The actuator moves the valve in response to an electrical command, providing on/off operation or modulating control when supported by the design. Integration with programmable logic controllers (PLCs) and distributed control systems (DCS) allows valve operation to be coordinated with other process equipment.

Types of Electric Actuated Valves

  • Electric Actuated Ball Valve: For pipeline isolation and shut-off.
  • Electric Actuated Butterfly Valve: For flow isolation in compact pipeline installations.
  • Electric Actuated Gate Valve: For on/off service where gate valve construction is suitable.
  • Electric Actuated Globe Valve: For applications requiring flow adjustment.
  • Electric Actuated Plug Valve: For isolation and flow control in compatible services.

Key Features

  • On/off or modulating operation, depending on actuator capability.
  • Remote control through compatible automation systems.
  • PLC and DCS integration.
  • Manual override on selected models.
  • Different valve body and trim materials for specific process conditions.
  • Power supply and control options based on actuator configuration.

How to Select an Electric Actuated Valve

Consider these factors when choosing a valve assembly:

  • Valve function: Select the valve type according to isolation or flow-regulation requirements.
  • Process conditions: Check fluid compatibility, operating pressure and temperature.
  • Actuator capacity: Confirm that the actuator provides sufficient torque or thrust for the application.
  • Electrical requirements: Match the power supply and control signals to the installed automation system.
  • Control method: Determine whether on/off operation or modulating positioning is required.
  • Maintenance needs: Consider operating frequency, access and whether a manual override is necessary.
