​​LEFB25ET-500C-R5: Intelligent Regulation, Precise Valve Control! Linear Electric Actuator Empowers Accurate Flow Control​

In process automation applications requiring precise valve positioning to regulate flow or pressure, actuators are demanded with extremely high thrust, accuracy, and intelligent control capabilities. The LEFB25ET-500C-R5 linear electric actuator integrates high thrust output, high-precision positioning, and intelligent control into one unit. Providing linear drive for control valves, gate valves, and more, it is a key actuating mechanism for achieving precise process control.​​Core Product Advantages​​

• ​​High Thrust Linear Output​​Delivers a high thrust of up to ​​500 kgf​​ (the 500 in the model likely indicates thrust), enabling it to operate large-bore or high-pressure differential control valves and gate valves, ensuring reliable actuation.
• ​​High-Precision Positioning Control​​Utilizes a precision motor and gearbox to provide high positioning accuracy (up to ±0.5% FS) and excellent repeatability, achieving precise adjustment of valve opening.
• ​​Integrated Intelligent Control​​Features a built-in integrated controller supporting ​​analog signals (4-20mA) / digital communication (e.g., Modbus, PROFIBUS)​​. It can receive control signals and provide valve position feedback for closed-loop control.
• ​​Non-Intrusive Setup & Commissioning​​Parameters are set and configured using an infrared setter or Bluetooth, eliminating the need to open the electrical housing. This maintains sealing integrity and ensures safe, convenient operation.
• ​​Multiple Safety Protections​​Equipped with torque overload protection, overheating protection, and motor stall protection. Its high IP68 protection rating makes it suitable for harsh operating conditions.

​​Typical Application Scenarios​​

• ​​Process Control:​​ Precise flow/pressure control for regulating valves in chemical, pharmaceutical, and water treatment plants.
• ​​Energy Management:​​ Flow regulation and balancing in heating systems and HVAC water circuits.
• ​​Water Supply & Drainage Systems:​​ Remote control of pump station discharge valves and network regulating valves.
• ​​Environmental Protection Equipment:​​ Precise valve adjustment in flue gas desulfurization and wastewater treatment systems.

​​Technical Parameters (Typical Values)​​

• ​​Output Thrust:​​ 500 kgf
• ​​Stroke:​​ Customized per valve requirements (e.g., 25mm / 50mm / 100mm)
• ​​Control Signal:​​ 4-20mA analog / Digital communication
• ​​Supply Voltage:​​ AC380V 3-phase / AC220V single-phase
• ​​Protection Rating:​​ IP68
