I am trying to determine the actuator torque required for my metal seated, concentric butterfly damper for smoke service in a fire heater.

Butterfly Damper Specifications
- 58" diameter
- 0.04 PSI dP
- 630 degrees F
- intended for SMOKE service
- sealing system is 316SST on 316SST.

I intend to use a pneumatic actuator.

Does anyone knows any design standard for sizing damper actuators?

Thanks in advance,

Paco.
