The SM24 is an old actuator that has been phased out. The new model is the SM24A… however please note:
- If you are replacing on a Damper application, then you are fine with the SM24A
- If you are replacing on a Valve application, you will need to verify the valve model and type as different alternative actuators and linkages may apply. You can contact us back with the exact model and we can confirm the correct replacement.
