Compact electric actuator

Electric valve actuators convert electrical power into mechanical motion for on/off or modulating control of valves. Offering more precise, stable control than pneumatic systems, they are widely used in sensitive processes in chemicals, energy, water treatment and HVAC.

Operation

  • An electrical signal (e.g. 4–20 mA) is sent to the actuator
  • The electric motor in the actuator converts the signal into motion
  • A gearbox increases the torque and transfers the motion to the valve stem
  • The valve is moved to the required position (open, closed or intermediate)
  • Position feedback reports the valve position to the control system

Advantages

  • Precise positioning and modulation
  • Remote automation – fully compatible with PLC and SCADA systems
  • Low maintenance – few moving parts
  • Quiet, clean operation – no air or oil required

Applications

  • Chemical and petrochemical plants
  • Water treatment and distribution systems
  • Food and pharmaceutical production lines
  • Power plants
  • HVAC systems
  • Marine and ship machinery
  • Fire-fighting and safety systems
