Belimo LF24-MFT Spring Return Rotary Actuator model It is an adjustable controller device for use in HVAC systems, which is widely used in controlling dampers due to its spring return capability and programmable function. This actuator operates on 24V AC/DC and has a torque of 35 in-lbs (4 Nm). The key features of this model are: 1. Modular control and spring return: Actuator works with 2-10V signal input or 4-20mA signal adjustment and returns the damper to safe position in case of power failure. 2. 95 degree rotation: For accurate and reliable applications, the range of rotation up to 95 degrees is provided. 3. Brushless motor and intelligent control: An advanced integrated circuit and microcontroller are used to control the constant rotation rate and prevent damage in blocking conditions. 4. Position Feedback: This device provides position feedback without the need for mechanical potentiometers. 5. Adjustment capabilities: The default parameters are set at the factory and can be changed by PC-Tool software or ZTH hand tool. Advantages: • Reducing the need for frequent repairs due to the robust design without mechanical wear parts. • Working time is independent from the amount of torque. • Suitable for safe applications in emergency situations. This device also has international quality certificates (ISO 9001) and includes a 5-year warranty. As a reliable supplier of all kinds of actuators and special sensors, including this model, Bahrani Industrial Group is ready to provide services.
