Bray Commercial D24-210 Actuator

The Bray D24-210 is a high-torque direct-coupled actuator designed for precise control in HVAC applications requiring 210 in-lb (24 Nm) of force. This non-spring return unit operates on a 24V AC/DC power supply and utilizes floating (3-point) control to modulate dampers and valve assemblies effectively. The D24-210 series is engineered for longevity in demanding environments, featuring an impact-resistant enclosure and a low-power consumption design that reduces transformer loading. Technicians appreciate the manual override button for manual positioning during commissioning and the universal mounting bracket that accommodates various shaft sizes. With a 150-second run time, this actuator ensures stable positioning for high-load air handling units and large-scale zoning dampers. The brushless DC motor technology ensures consistent performance without the maintenance requirements of traditional brushed motors, making it a reliable choice for technical retrofits and new commercial installations.

Key Benefits

• 210 in-lb Torque Output: Provides ample power for large dampers and high-pressure butterfly valve applications.
• Precise Floating Control: Enables accurate 3-point modulation for superior temperature and airflow management.
• Tool-Free Installation: Simple direct-coupling mechanism speeds up field replacement and reduces labor costs.
• Independent Direction of Rotation: Easily switch between clockwise and counter-clockwise operation via the integrated switch.
• Long Service Life: Designed with electronic stall protection to prevent motor burnout under high-load conditions.

Common Questions

Is the Bray D24-210 a spring-return actuator?
No, this is a non-spring return (NSR) motor. It will maintain its last position upon loss of power rather than returning to a fail-safe position.

Which shaft sizes is this actuator compatible with?
The universal clamp accommodates round shafts from 3/8" to 1/2" and square shafts from 1/4" to 1/2", making it highly versatile for most damper actuator replacements.

Can I use this for proportional 2-10V signals?
No, the D24-210 is specifically a floating control actuator. For 0-10V or 2-10V modulated signals, the Bray 'proportional' series counterparts are required.
