What information do I need to order the right actuator?
To ensure accurate actuator selection, provide the damper size and blade type, required torque rating (check damper manufacturer specifications), control signal type (0-10V, 2-10V, floating, or digital protocol), voltage available at installation location (24VAC, 120VAC, or 208-277VAC for line-voltage models), and whether you need spring-return or non-spring-return operation. If you're replacing an existing actuator, the current model number helps our team identify a direct replacement or compatible alternative. Our specialists assist with sizing verification when specifications are unclear.
What torque rating do I need for my HVAC damper?
Torque requirements depend on damper size, blade configuration, and system static pressure. A 24-in round damper may require only 35 in-lb, while a 48-in rectangular damper in a high-static system could need 180 in-lb or more. Consult the damper manufacturer's torque charts or contact BCS technical support for sizing assistance.
