Belimo CQB24-SR-L Actuator
The Belimo CQB24-SR-L is a high-performance non-spring return actuator designed specifically for modular control in HVAC systems utilizing ZoneTight zone valves. Operating on 24V AC/DC power, this actuator provides a proportioning control signal of 2 to 10 VDC, ensuring precise modulation for terminal unit applications. With a 75-second run time, it offers consistent torque for reliable valve positioning without the complexity of mechanical fail-safe mechanisms. The "L" designation indicates a left-hand mounting orientation, crucial for specific manifold or piping configurations where space is constrained. Engineered for low power consumption and long-term durability, the CQB24-SR-L features a brushless DC motor and electronic stall protection, eliminating the need for limit switches. This modulating actuator is the industry standard for contractors requiring a compact, NSR actuator that integrates seamlessly with DDC controllers for pressure-dependent or pressure-independent hydronic circuits.
Key Benefits for Installation and Performance- Precise Flow Control: The 2-10 VDC feedback signal allows for accurate valve positioning and system monitoring.
- Simplified Installation: Features a tool-free snap-on mount for rapid attachment to Belimo CQ series valve bodies.
- High Operational Efficiency: Low power consumption during operation and holding reduces transformer sizing requirements.
- Manual Override: Includes a manual override lever to assist in system commissioning and troubleshooting.
- Compact Footprint: Designed for tight spaces typically found in fan coil units and radiant floor manifolds.
What is the difference between the CQB and the CQ series actuators?
The CQB series, like the CQB24-SR-L, is designed for localized zone control with specific mounting orientations and timing optimized for terminal applications compared to larger CCV actuators.
Does this actuator require a specific transformer?
It operates on a standard 24V AC/DC supply; however, ensure the VA rating accounts for the maximum power consumption of all connected units on the modulating control circuit.
Can I use this for fail-safe applications?
No, this is a non-spring return (NSR) model. For applications requiring a fail-safe position upon loss of power, a CQK series actuator should be utilized.
