Technical Specifications

Applications

• Damper control in air handling units, VAV boxes, and ventilation systems

• Valve actuation in HVAC hydronic or air systems (when torque requirement matches 75 lb-in)

• Building automation systems requiring actuator feedback or external signal via auxiliary switches

• New installations or retrofit projects requiring a reliable, foot-mounted actuator

• Zone control in commercial or residential HVAC systems

Before installation, verify that torque output, shaft coupling, and control voltage match your system requirements.

Installation & Use Notes

• Installation should be carried out by a qualified HVAC or automation technician

• Ensure the power supply is 120 V AC before wiring the actuator

• Secure foot-mounted housing properly to prevent vibration or misalignment

• Confirm correct coupling between actuator shaft and damper/valve to avoid binding

• Use auxiliary switches if external feedback or safety interlock functionality is needed

• After installation, cycle the actuator to confirm smooth, full-range motion and correct auxiliary switch operation
