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 […]
