Fielbus Card Introduction

Basic Type Multi-Turn Electric Actuators BD60-C8 come with integrated bus cards for advanced smart control. The bus cards support mainstream industrial communication protocols, such as Modbus-RTU and Profibus-DP, ensuring compatibility with various factory automation systems. They enable real-time data transmission between the actuators and the central control room, allowing operators to remotely monitor key parameters like operating torque, motor temperature and valve opening degree.

The bus cards are designed with strong anti-interference performance. They use shielded communication circuits and surge protection components, maintaining stable signal transmission even in harsh industrial environments with high electromagnetic interference, such as near large-scale compressors or transformers. Basic Type Multi-Turn Electric Actuators BD60-C8 adopt plug-and-play designs for the bus cards, simplifying installation steps and reducing on-site configuration time. The cards are also equipped with detailed fault diagnosis functions. When the actuators encounter issues like communication interruptions or parameter errors, they output clear fault codes to help operators quickly locate and resolve problems.

Furthermore, the bus cards support remote parameter management. Operators can adjust the actuators’ working parameters (such as torque limits and speed settings) through the control system, eliminating the need for on-site operation. They also support batch parameter backup and restoration, which is particularly useful for projects with multiple actuators, improving configuration efficiency and ensuring parameter consistency across the system.

Travel Control Mechanism Introduction

Basic Type Multi-Turn Electric Actuators BD60-C8 own high-precision travel control mechanisms. These mechanisms manage heavy-load valve strokes with excellent accuracy in operation. In addition, they combine high-strength decimal gear sets, durable actuator rods and wear-resistant cams. They also integrate multiple reliable micro switches to track and control valve rotation turns precisely. Meanwhile, drive pinions in the actuators’ reducers connect tightly to decimal gear sets. They convert output shafts’ rotation into accurate and stable stroke control signals.

For valves with extra rotation turns like large-diameter gate valves, users can rotate cams by 180° or 270°. This flexible adjustment triggers micro switches at exact and desired stroke positions. Moreover, it greatly improves the actuators’ adaptability to various high-load valve types. It keeps precise control for valves that demand long stroke ranges. The mechanisms install two pairs of high-performance micro switches. Specifically, two switches serve valve open direction and another two support close direction. Each micro switch provides normally open and normally closed contacts. Furthermore, they support flexible control circuit designs for complex industrial control systems.

Basic Type Multi-Turn Electric Actuators BD60-C8 apply high-precision gear fitting in travel control mechanisms. Gears use wear-resistant alloy materials and adopt precision machining techniques. Besides, they reduce wear effectively during long-term high-load operation. This design maintains consistent stroke control accuracy in continuous working. It also prevents valve operation errors from mechanical wear or part loosening. In addition, they match actuators’ stroke with valves’ actual opening and closing range perfectly. They deliver stable and reliable control for large-scale industrial pipelines steadily.

In the chemical industry, they adapt to corrosive and high-pressure environments, such as large chemical synthesis plants and petrochemical refineries. They manage process valves in chemical raw material transportation and reaction vessel pipelines, with excellent pressure resistance to prevent media leakage.

In shipbuilding, Basic Type Multi-Turn Electric Actuators BD60-C8 match valves in ship power systems and hull pipeline networks. They withstand strong vibration and harsh marine environments (such as salt spray corrosion), maintaining stable operation for long periods. In large-scale water treatment plants, they operate valves in sewage treatment pipelines, sludge discharge systems and raw water intake lines, controlling the flow of media to ensure efficient water treatment processes.

Their optional explosion-proof versions expand their application to more hazardous areas.
