leak-resistant connection within the refrigerant circuit

Always verify that the actuator and valve packing can handle the specific system media temperature before installation

though it is standard practice to install the regulator in a horizontal upright position to ensure easiest access for pressure adjustments and venting

Belimo AFB24-S Actuator Refrigerant and ceramic wire nuts forThe Belimo AFB24 S is a heavy duty spring return damper actuator engineered for on off control in demanding HVAC applications. Delivering a robust 180 in lb torque, this unit is designed to operate reliably within 24VAC or 24VDC circuits, ensuring failsafe positioning for fire and smoke dampers or large control air valves during power loss. The integrated auxiliary switches (2x SPDT) provide precise position feedback to the building management system,
