Belimo CQ24A-SR-T - rotary actuator for zone valves

Belimo CQ24A-SR-T – actuator for zone valves

Electronic rotary actuator with modulating control. The Y control signal determines the actuator position, while the U measuring voltage provides electrical indication of valve position from 0...100%.

Key features and parameters

• Torque: 1 Nm; running time: 75 s / 90°.
• Rated voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Y operating range: 2...10 V; U position feedback signal: 2...10 V.
• Power consumption during operation and at rest: 0.3 W; power for cable sizing: 0.6 VA.
• Power and control connection: 1.5 mm² terminals (ø6.3...6.8 mm cable, 4-core).
• Tool-free snap-on mounting and mechanical position indicator.
• Rotation angle adjustment using a clip in 2.5° increments enables setting the valve's maximum flow.
• Manual adjustment after detaching the actuator.
• Degree of protection IEC/EN: IP40; protection class IEC/EN: III, Safety Extra-Low Voltage (SELV).

After each flow setting change using the limit clip on modulating actuators, adaptation must be initiated.
