Different types of Actuator

  Process engineers have many options with respect to actuators for manual, pneumatic, hydraulic and electric lift rod valves. Manual actuators meet simple on and off needs. Pneumatic valve actuators are fast and economical. Hydraulic systems can be a solution for powerful applications and remote installations. However, for critical process control applications, electric valve actuators can provide the work that process engineers do: increase productivity, increase efficiency and reduce downtime. In other words, electric actuators improve the process and reduce costs. There are pros and cons for each valve operation option and we will see it here. Electric actuators:- Electric valve actuators, especially electric valve actuators with brush-less servo motors, handle complex motion profiles, provide high strength and high speed, and provide excellent accuracy and repeat-ability. These advantages make electric actuators particularly suitable for process control applications. Alth
