The Swiss company Aqua Solar AG is showing its automatic backwash valves which are available in sizes DN40 to DN125.

Due to high backwash speeds and low pressure loss, the Besgo valve ensures particularly good washing results.

Furthermore, the circulation pump must not be switched off when changing. In the event of a power failure, the Besgo valve is automatically set to “Filter”, making any unintentional draining of the pool impossible.
