Belimo ZONE24NC-S Actuator

For contractors demanding reliable zone control, the Belimo ZONE24NC-S Actuator delivers robust performance. This 24V zone valve actuator is engineered for precise on/off control in HVAC systems, ensuring optimal flow management. As a spring return normally closed actuator, it defaults to a safe, closed position upon power loss, a critical feature for system integrity. Operating on both 24Vac and 24Vdc, it offers versatile integration into various setups. With a running power consumption of 6.5W and 7VA for wire sizing, it’s designed for efficiency. The integrated auxiliary switch actuator (1x SPST, 5A @ 120V) provides valuable feedback for system monitoring or sequencing additional equipment. Its NEMA 1 / UL Enclosure Type 1 rating and IP20 protection category confirm its suitability for typical indoor mechanical room environments. Installation is straightforward, featuring a manual override hand lever and a swift 5-second spring return time for fail-safe operation, with a motor run time of 20-40 seconds for controlled modulation.

• Reliable Fail-Safe Operation: Spring return mechanism ensures the valve closes securely upon power interruption, enhancing system safety.
• Versatile Power Compatibility: Operates seamlessly on both 24Vac and 24Vdc, simplifying integration into diverse control circuits.
• Integrated Auxiliary Feedback: A single SPST auxiliary switch provides critical status indication or enables control of other components.
• Durable Construction: Rated NEMA 1 / UL Enclosure Type 1 and IP20 for dependable performance in standard mechanical room conditions.
• Efficient Control: Low power consumption (6.5W running, 7VA for wire sizing) contributes to energy-conscious system design.

Common Questions

• How do I wire a Belimo ZONE24NC-S actuator into my existing control panel? This actuator utilizes a straightforward on/off control signal, compatible with standard 24Vac/dc circuits. Refer to the technical data sheet for specific terminal assignments and recommended wiring practices for the main power and auxiliary switch.
• What is the typical power draw for the Belimo ZONE24NC-S during operation? The unit draws 6.5W while running, with a power consumption for wire sizing rated at 7VA. This allows for efficient circuit design and load calculation.
• Is the Belimo ZONE24NC-S compatible with all 24Vac HVAC zone control systems? Yes, its 24Vac/dc compatibility and on/off control signal make it broadly suitable for most low-voltage HVAC zone control applications requiring a normally closed, spring-return actuator with auxiliary feedback. Always verify valve body compatibility.
