How to Protect Electric Actuators from Corrosion

Blog,Valves Study | Oct.26.2020

COVNA, as a professional electric actuators manufacturer over 20 years, including:

  • Modulating electric actuators: Adjust open/close angle from 0 to 90 degree. AC/DC power supply, signal control and manual override. High torque up to 4000Nm.
  • On/off type electric actuators: 0 degree rotation. AC/DC power supply, signal control and manual override. High torque up to 4000Nm.
  • Intelligence electric actuators: Adjust open/close angle from 0 to 90 degree. LED display screen to allow you check the open/close angle easier. AC/DC power supply, signal control and manual override. High torque up to 4000Nm.

  In daily life, except for the chemical industry, we seem to rarely touch corroded electric actuators. What should I do if the electric actuator is corroded?
   We know that electric actuators are generally made of metal materials. Under normal circumstances, the corrosion of electric actuators is due to damage to the surface, which causes chemical changes to themselves and the surrounding environment. In addition, the corrosion of the electric actuator has a serious impact on the life cycle of the electric actuator. The use of this electric actuator is very dangerous in the chemical industry, because it is uncertain when this kind of corroded electric actuator will suddenly explode. If you lose your ability to work quickly, there is a high probability that production will stop. In a major accident, there will often be material losses and casualties. Therefore, it is not wrong to say that this corroded electric actuator is a time bomb.
   There are many ways to solve the corrosion of electric actuators, the following editor will talk about the four commonly used:
   Type 1: Apply anti-corrosion paint on the surface of the electric actuator.
   Type 2: Use plating technology on the surface of electric actuator products.
   Type 3: Use blocked water or alcohol to derust the electric actuator.
   Type 4: Use a volatile corrosion inhibitor to smear the surface of the electric actuator.
