Find all parts for your ventilation system at iacs, the Free Delivery and 1-2 Delivery is available for all the Belimo Actuators in stock

The Belimo CQ24A-SR is a type of Actuator used in HVAC and ventilation systems.

This kind of Actuator rotates the damper in order to control it.

The force applied by the Torque of the CQ24A-SR is 1 Nm.

This Rotary Actuator needs to be supported by a power supply of 24Vac/Vdc.

If you have questions concerning size or installation, refer to the Belimo custom datasheet above or email iacs for individualised support.

CQ24A-SR Zone Rotary Actuator, AC/DC 24 V, 75 s

• Modulating
• Operating range DC 2...10 V
• Motor running time 75 s
• Connection PVC cable 1 m, IP 40
• Adjustable flow rate value

Mode of operation: The actuator is connected with a standard modulating signal of DC 0...10V and drives to the position defined by the positioning signal.

Simple direct mounting: Tool-free snap assembly. The actuator can be plugged on the valve by hand (Caution! Just vertical movements). Pins must match the holes on the flange. The mounting orientation in relation to the valve can be selected in 180° increments. (Possible two times)

Manual override: Click out the actuator and rotate the valve stem with the help of the actuator.

High functional reliability: The actuator is overload protected, requires no limit switches in intermediate positions and automatically stops when the end stop is reached (at rest).

Adjustable angle of rotation: The angle of rotation of the actuator can be changed by clip in 2.5° increments. This is used to set the maximum flow rate of the valve.

kv setting: Adjustable kv-values (C2..Q- ..) / max-values (C2..QP (T) - ..) are given in the respective zone valve data sheets. 2-way valve: Remove end stop clip and place at desired position. 3-way valve: Remove end stop clip (change-over application).
