Actuators An actuator is a device that converts energy (electrical, pneumatic, or hydraulic) into mechanical motion to operate valves (control valves, dampers, cocks):
Main functions:
- Process automation - replacing manual control with remote or programmed control.
- Precise regulation - real-time control of parameters (pressure, flow, temperature).
- Emergency shutdown - fast shutoff of flow in the event of a leak or accident.
- Integration with process control systems - operation as part of SCADA systems. Applications:
- Oil and gas industry: operating gate valves on pipelines and gas lift systems.
- Water supply and sewage: regulating water supply.
- Power engineering: controlling steam and heat-transfer fluid at CHP plants.
- Chemical industry: dosing aggressive media.
- Food industry: hygienic solutions for liquids and paste-like products.
How it works: - Receives a signal from a sensor or controller (for example, “open the valve 50%”).
- Converts energy into motion (shaft rotation or linear travel).
- Transmits force to the valve (ball valve, damper, and so on).
- Confirms position using feedback sensors. Usage examples:
- On a gas pipeline: A Rotork electric actuator smoothly regulates gas supply based on pipeline pressure.
- On an oil well: A Festo pneumatic actuator shuts off the discharge line in an emergency in the event of a leak.
- At a CHP plant: A Parker hydraulic actuator controls the boiler’s steam damper. Main actuator types and their advantages:
| Type | Operating principle | Advantages | Disadvantages | Example application | Top brands |
