Belimo AFRX24-MFT
Configurable Valve Actuator, Spring return, AC/DC 24 V, 2...10 V, MFT/programmable

Product Details
AFR series actuators are used with B6 Series, Two Way Flanged Ball Valves.
Application: This valve is typically used in air handling units on heating or cooling coils, and fan coil unit heating or cooling coils. Some other common applications include Unit Ventilators, VAV box re-heat coils and bypass loops. This valve is suitable for use in a hydronic system with variable or constant flow. Belimo damper actuators and control valves with Multi-Function Technology (MFT) are an excellent way to standardize your product line while reducing the number of different actuators needed. MultiFunction Technology offers a wide variety of programmable control inputs and feedback signals. Parameters can be set for voltage control (VDC), time proportional control (PWM), floating point, on-off, feedback signal, or torque output. Parameters can be changed on-site to optimize/enable application. You can also set, modify or read position, running time, mechanical working range, address, status, and diagnostics.
