Bray Commercial D24-70 Actuator
The Bray D24-70 Actuator is a high-performance 24Vac/dc non-spring return actuator designed for the precise control of butterfly and ball valves in HVACR systems. Operating with an on/off (floating) command signal, this NSR direct coupled actuator delivers 70 lb-in (8 Nm) of torque, ensuring reliable operation for medium-sized dampers and valve assemblies. Built for long-term field durability, it features a brushless DC motor and an IP54-rated enclosure to protect against dust and moisture in mechanical rooms. The unit includes a manual override button and a universal shaft clamp that simplifies installation on various damper shaft sizes. Technical specifications focus on 70 lb-in torque output, a 90-second run time, and low power consumption at both 24V AC and DC power supplies. For contractors seeking a 24V non-spring return damper actuator, the D24-70 provides a robust solution for multi-zone air distribution and hydronic flow control where failsafe positioning is not required.
Key Benefits
- Universal Mounting: Direct-mount design with a self-centering shaft adapter reduces installation time and improves shaft grip.
- High Torque Output: Provides 70 lb-in of torque, sufficient for driving high-differential pressure ball valves without stall issues.
- Efficient Power Usage: Uses a brushless DC motor for consistent speed and reduced energy draw compared to traditional AC motors.
- Selectable Direction: Includes a manual direction pulse switch to easily reverse rotation based on valve or damper orientation.
- Enhanced Durability: The NEMA 2 (IP54) housing ensures internal gears remain protected from common environmental debris.
Common Questions
How do I wire the Bray D24-70 for 3-point floating control?
The D24-70 supports 3-point floating control by utilizing the common, CW, and CCW terminals. Ensure your controller’s pulse matches the 90-second drive time for accurate positioning.
Can the Bray D24-70 be used for failsafe applications?
No, this model is a non-spring return actuator. For applications requiring a safety return position upon power loss, a spring-return series actuator should be specified.
What is the maximum shaft diameter for the universal clamp?
The universal clamp on the D24-70 typically accommodates round shafts up to 5/8 inch and square shafts up to 1/2 inch.
