Types of Actuators and How to Choose the Right One

Actuators can be classified based on their driving method into the following categories: 1. Electric Actuators Electric actuators use an electric motor as the power source, converting electrical energy into mechanical motion to drive the valve. Advantages: ✔ Adjustable speed✔ High positioning accuracy✔ Large torque output Disadvantages: ✖ Thermal effects of the motor may trigger […]

How Humidity Reduces the Lifespan of Actuators (Electric Valves)?

Humidity is well known to cause damage to electronic components. One of the primary ways humidity reduces the lifespan of electric actuators is through ionic migration short circuits. 1. What is Ionic Migration Short Circuit? Ionic migration occurs when moisture and contaminants on a circuit board facilitate the movement of ions between conductors, leading to […]

What Does the S2 Duty Cycle Mean in Actuators (Electric Valves)?

Many people have questions about the S2 duty cycle in actuators or electric valves. What does it mean, and why is it defined this way? 1. The Origin of S1, S2, S3, and S6 Duty Cycles The S1, S2, S3, and S6 duty cycles originate from electric motor classifications, with a primary focus on thermal […]

Why Do Some Actuators Need Explosion Protection?

  1. What is an Explosion? An explosion occurs when flammable substances mix with oxygen and ignite under certain conditions. If the reaction speed exceeds the speed of sound, it results in a destructive explosion wave. 2. What is Explosion Protection? To prevent explosions, at least one of the three key factors must be controlled: […]
