Schneider Electric (Barber Colman) AL-161-4 3-Way Air Switching Valve 8/13 PSI

The Schneider Electric (Barber Colman) AL-161-4 3-Way Air Switching Valve is a component that is used to regulate the flow of air between two or more ducts in HVAC systems to enable the system to supply conditioned air to various areas or appliances. It is powered at 8 to 13 PSI, which is a fine pneumatic actuation to switch accurately. It is a process of attaching the valve in place and connecting it to the control or pneumatic lines. In the system, it guides airflow, equalizes pressure, and promotes effective ventilation and air circulation systems in normal operation.
