Rotork Electric Actuator

Rotork Electric Actuator

For successful process automation, it is of utmost importance to ensure that the valve itself meets the specific requirements of the process and the media in the pipeline. Usually the production process and the process medium determine the type of valve, the type of spool and the construction and material of the valve internals and valve. As shown in the figure "Precision Miniature".After the valve is selected the next step is to consider the automation requirements i.e. the actuator selection. The actuator can be considered simply by two basic types of valve operation. You are welcomed to come to our factory to buy the latest selling, low price, and high-quality Rotork Electric Actuator.

Advantages

The main advantages of electric actuators are high stability and constant thrust that can be applied by users. The thrust generated by the largest actuator can be as high as 225,000kgf. Only hydraulic actuators can achieve such a large thrust, but the cost of hydraulic actuators is higher than that of electric actuators. much higher.

The electric actuator's ability to resist deviation is very good, and the output thrust or torque is basically constant, which can well overcome the unbalanced force of the medium and achieve accurate control of the process parameters, so the control accuracy is higher than that of the pneumatic actuator. If equipped with a servo amplifier, it can easily realize the interchange of positive and negative action, and also can easily set the state of broken signal valve position (hold/fully open/fully closed), and when it fails, it must stay in the original position, which is not possible with pneumatic actuators, and pneumatic actuators must be protected by a set of combined protection system to realize the position preservation.
