Types of Actuators

Actuators are mechanical or electro-mechanical devices that provide controlled and limited movements or positioning which can be operated electrically, manually or by various fluids. The two basic motions are linear and rotary. The linear actuators can convert energy into the straight line motions. The positioning for the application have a push and pull function which gives it more power. Some linear actuators can be unpowered and they can be manually operated by the use of a rotating knob or a hand wheel. The rotary actuator can convert energy to provide the rotary motion.  Each individual actuator type has a version for various power configurations and they come in many styles and sizes depending on the application.

 

 

 

Here are the different types of actuators that are commonly used in plants:

  • Electric linear
  • Electric rotary
  • Fluid power linear
  • Fluid power rotary
  • Linear chain actuators
  • Manual linear
  • Manual rotary

Powered actuators are incorporated motors, cylinders and other motion devices to produce rotation or linear translation. The rack and pinion arrangements, ball screws and other kinds of power transmission components are connected to the motor to generate more energy to load. The actuators are separated by the motion and the power source. The linear actuators produce the push and pull action.

The rotary actuators produce a rotational motion which ensures the performance of the linear actuators can begin with a rotary prime mover as well as the motor. The rotation is converted to the linear motion through a power screw or a similar device. A lot of rotary actuators can begin with a linear device such as a hydraulic cylinder which can provide circular motion through a rack and a pinion arrangement.

Valve-Actuator Types

There are three types of actuators namely electric, pneumatic and hydraulic. The pneumatic valve actuators are powered by air and gas. The air pressure acts as a piston to create the linear force to close the open valve. The power plants have always used pneumatic actuators to drive the control valves throughout the facilities. The… Continue Reading

New developments in pneumatic valve

Pneumatics are widely used in packaging machines to drive the motion and he actuates machine sequences. It is reliable, compact and a lightweight technology that provides effective control and actuation to help with packaging machines and the designers create innovative systems that are unique while staying competitive. Pneumatic valve technology plays a big role in… Continue Reading

Valve Leakage

Leaking isolation valves are found in the steam generation industry and they are equally widespread in the detriment to the P&L statements worldwide. The thermal engines and steam plants are powered by different energies and the greater fuel efficiency. The valves maintain the separation by isolating the high energy processes from the low energy processes.… Continue Reading

Valve installation

Butterfly valves are designed for installation between the ANSI Class 125/150 flat or raised face flanges that are used to regulate the flow in a pipeline. Lined pipes, heavy wall pipes and flanges need to have a minimum allowable inside the diameter at the center body face to clear the disc sealing edge when opening… Continue Reading
