The BESGO valve is a pneumatic valve designed to change the flow within the use of one pump and multiple attractions or to regulate the flow through the overflow and bottom drain (3-way design).

The great advantage of these valves is maximum operational safety, the change of position can take place even when the filter pump is switched on, however, it is always more appropriate and safer to adjust the valve without water flow (when the circulation pump is switched off)

Schematic presentation of 3-way BESGO valve operation - recirculation through the bottom drain using the AS Control Plus unit -  the water can get aspirated as a subject to the temperature either over the overflow channel or over the bottom drain.
