Hydraulic actuator

Hydraulic actuators convert pressurised hydraulic fluid into mechanical motion for on/off or modulating control of valves. They are preferred where high torque and harsh conditions are involved.

Operation

  • A hydraulic pump supplies pressurised oil
  • The oil moves the piston or cylinder in the actuator
  • The motion is transmitted to the valve through gearing or directly via the stem
  • The valve opens, closes or is held in a set position
  • Feedback systems ensure accurate positioning

Advantages

  • High torque – ideal for large valves
  • Withstands harsh conditions – dust, humidity, temperature swings
  • Robust and long-lasting
  • Compatible with modular control systems
  • Spring-return or double-acting versions

Applications

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