Belimo CQKB24-SR-RL Actuator
The Belimo CQKB24-SR-RL is a high-performance spring return zone valve actuator designed for reliable proportional control in closed-loop hydronic systems. Operating on a 24VAC/DC power supply, this actuator utilizes a 2 to 10 VDC control signal to provide precise 0-90 degree rotation, ensuring accurate flow modulation. Built with a NEMA 2 (IP54) rated enclosure, it is suitable for demanding mechanical environments where moisture and debris protection are required. The fail-safe spring return mechanism ensures the valve returns to its normally closed (NC) position during power loss, preventing uncontrolled flow. This unit integrates seamlessly with Belimo ZoneTight pressure independent valves and conventional zone valves, offering a running time of 75 seconds and a fail-safe timing of less than 25 seconds. For contractors, the tool-free snap-on mounting and 5-foot plenum-rated cable simplify field installation, reducing labor time and ensuring a secure connection to building automation systems.
Key Technical Benefits:
- Fail-Safe Reliability: Mechanical spring return ensures the system defaults to a safe state during power interruptions.
- Proportional Control: Accepts 2-10 VDC modulation for precise temperature and flow management.
- High Torque Efficiency: Optimized for low-profile zone valve applications without compromising shut-off force.
- Durable Construction: The NEMA 2 rated housing protects internal components from vertical dripping water and dust.
- Simplified Integration: Equipped with a pre-wired plenum cable for rapid 24V hookups to HVAC controllers.
Common Installation Questions:
Can the CQKB24-SR-RL be mounted in any orientation?
This actuator can be mounted in multiple orientations, but it is recommended to avoid mounting it upside down to maintain its NEMA 2 rating and prevent moisture accumulation.
What is the power consumption during operation?
The unit is engineered for high energy efficiency, consuming approximately 2.5W during motor operation and 0.5W in the holding position.
Does this unit support manual override?
Yes, the CQKB series includes a manual override feature, allowing technicians to position the valve during commissioning or maintenance without power.
