Belimo CQ24A-SR - Rotary actuator for zone valves

Belimo CQ24A-SR – actuator for zone valves

Electronic rotary actuator with modulating control. The measuring voltage U is used to electrically indicate the valve position from 0...100% and as a control signal for other actuators.

Key features and parameters

• Torque: 1 Nm; rated voltage: AC/DC 24 V, 50/60 Hz.
• Operating range of control signal Y: 2...10 V; position feedback signal U: 2...10 V.
• Running time: 75 s / 90°; power consumption during operation and at rest: 0.3 W; power rating for cable sizing: 0.6 VA.
• Power and control connection: Cable 1 m, 4x 0.34 mm².
• Degree of protection IEC/EN: IP40; protection class IEC/EN: III, Safety Extra-Low Voltage (SELV).
• Tool-free snap-on mounting; mechanical position indicator.
• The rotation angle can be adjusted using a clip in increments of 2.5° to set the valve's maximum flow rate. After each flow setting change using the travel limiter clip on modulating actuators, run an adaptation.
• Manual adjustment is possible by removing the actuator and turning the valve stem using the actuator.
