DCL-250 Actuator Runs Fault-Free for 10 Years

Customer Reached Out to Us Again A customer contacted us to place a new order for electric actuators. However, the nameplates on the previously installed actuators had been corroded, making it impossible to identify the product model. The customer sent site photos for model confirmation. 13 Years of Reliable Operation with DCL-250 Actuators After analyzing […]

Tipos de atuadores e como escolher o mais adequado

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 […]

Como a umidade reduz a vida útil dos atuadores (válvulas elétricas)?

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 […]

O que significa o ciclo de trabalho S2 em atuadores (válvulas elétricas)?

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 […]

Os atuadores DCL podem ser usados em áreas de alta altitude?

High-altitude environments present unique challenges that can impact the performance of DCL electric actuators. This report evaluates their usage at 3,000 meters above sea level. 1. How High Altitude Affects Electrical Products As altitude increases:✔ Air density and pressure decrease, leading to lower insulation strength and increased risk of electrical breakdown.✔ Cooling efficiency decreases, causing […]

Por que os sinais de saída de tensão oscilam em determinadas condições?

  1. Voltage Signal Transmission Path As shown in Figure 1, a voltage signal transmission system consists of three key components: Negative feedback voltage output circuit Signal transmission cable Includes parasitic capacitance (C1) and parasitic inductance (L1), which depend on cable length and wiring layout. Input signal acquisition circuit May include a low-pass filter (L2, […]

Como configurar os atuadores liga/desliga com o transmissor de posição?

1. Mechanical Installation 1. Mechanical Installation Refer to the “How to Install the Actuator onto the Valve” section to correctly install the actuator onto the valve and manually operate it to confirm proper functioning. Follow the guidelines in “How to Set the ON-OFF Electric Valve” to properly adjust the actuator’s electrical limits (close limit CLS […]
