Belimo ZONE24NO-S Actuator
For contractors requiring dependable zone control, the Belimo ZONE24NO-S actuator delivers robust performance in hydronic heating and cooling systems. This spring return valve actuator is engineered for precise On/Off control, operating efficiently on 24V AC/DC power. Its normally open configuration ensures fail-safe operation, returning to its open position upon power interruption, a critical feature for maintaining system integrity. The integrated auxiliary switch (1x SPST, 5A @ 120V AC or 0.4A @ 24V AC) provides valuable feedback or enables sequential control of other components. With a rapid fail-safe running time of less than 5 seconds and a 90° angle of rotation, the ZONE24NO-S is a reliable choice for managing water flow in various applications. Its NEMA 1 enclosure and 18-inch wire leads simplify installation and ensure durability in typical HVACR environments.
Key Benefits
- Fail-Safe Operation: Spring return mechanism ensures the valve defaults to a normally open position upon power loss, enhancing system safety.
- Integrated Auxiliary Switch: Provides flexible control options and system status feedback for advanced automation.
- Versatile Power Input: Compatible with 24V AC/DC systems, offering broad application flexibility.
- Precise Control: Delivers accurate On/Off modulation for optimal hydronic system performance.
- Durable Construction: Features a NEMA 1 enclosure, built to withstand common HVACR operational conditions.
Common Questions
- What are the specific wiring requirements for the auxiliary switch on the ZONE24NO-S?
- Can this actuator be directly mounted to various zone valve body types, or are adapters required?
- What is the expected operational lifespan and maintenance schedule for this spring return actuator?
- How does the 24V AC/DC compatibility impact system design and power supply considerations?
