Belimo AFRB24-SR Actuator R-407A using a mixing tube isThe Belimo AFRB24 SR Actuator is a robust 180 in lb spring return actuator engineered for modulating control in demanding HVACR applications. Operating on a 24Vac Vdc power supply, this unit provides precise proportional control using a 2 10 Vdc signal, which can be adapted for 4 20 mA inputs with the addition of a 500 resistor. Designed for high torque requirements, it is a reliable choice for larger control valves and dampers where a mechanical fail
