BESGO DN50 Spindle Valve (Aqua Solar AG)

The BESGO DN50 piston valve from Aqua Solar AG is a professional solution for automatic control of water or air flow in large-volume swimming pool filtration systems. The hydraulic drive ensures smooth and silent operation without electricity, and the "normally closed" design guarantees that the pool will not be accidentally drained even if pressure is lost in the system.

The body is made of high-quality PVC and stainless steel, and the seals are made of ozone-resistant Viton, ensuring durability even when working with ozonated or chlorinated water. 90° swivel connections allow the valve to be connected to any filter without additional adapters.
