Kapan Memilih Aktuator Kontrol Proses?
Application Background of Process Control Actuators In many process control systems, it is necessary to achieve highly accurate and consistent control of the flow rate of liquids or gases through an automated control system (PLC/DCS). Due to the high precision required, such systems often need to make continuous and precise small adjustments to control valves […]
Pengujian Interferensi Elektromagnetik untuk Aktuator Listrik (EFT)
The Increasingly Harsh Electromagnetic Environment in Industrial Sites As industrial electrification and intelligence continue to advance, an increasing number of high-power electrical devices (such as kilowatt-level motors, frequency converters, and inverters) are being integrated into industrial process control systems. Consequently, the electromagnetic environment in industrial sites is becoming more complex. In such a challenging electromagnetic […]
Jenis-Jenis Katup Umum dan Fitur-Fiturnya
Butterfly Valve Working Principle: A butterfly valve uses a disc to control the flow of fluids or gases. The disc is mounted on a shaft, and when the handle is turned, the disc rotates 90 degrees to allow or block the flow. Features: Simple structure, compact size, low flow resistance, commonly used in large flow […]
Cara Kerja Aktuator dengan Fungsi Bus – Modbus, CAN, Ethernet, Profibus
When you install a DCL electric control valve with bus functionality on a pipeline, you can control a set of electric control valves through the bus (Modbus, CAN, Ethernet, Profibus) to achieve synchronized control of the valve cluster. The control system communicates with the actuator via a bus communication protocol, sending commands to control the […]

Jenis-Jenis Aktuator dan Cara Memilih yang Tepat
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 […]
Bagaimana Kelembapan Mengurangi Masa Pakai Aktuator (Katup Listrik)?
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 […]
