Belimo NRC24A-SR - rotary actuator for ball valves

Belimo NRC24A-SR – rotary actuator

Modulating actuator for ball valves, controlled by an analogue Y signal. The U feedback voltage provides an electrical indication of valve position from 0...100% and can also serve as a control signal for other actuators.
