Belimo CQD24A-SR-T - rotary actuator for zone valves

Belimo CQD24A-SR-T rotary actuator

Electronic rotary actuator for zone valves, controlled by a Y signal. The U measurement voltage provides electrical indication of valve position from 0...100% and serves as a control signal for other actuators.

Key features and specifications
