• Good water treatment is not possible without regular and good backwashing, an absolute must
• The Besgo valve is a reliable mechanical automatic backwash valve, manufactured by the company Besgo in Switzerland
• Operated by water or air pressure via a 230 V solenoid valve, air is preferred
• In the rest position, the valve is in the filtering position, so in the event of a power failure the bath is not emptied, optimal safety. When the solenoid valve is energized, backwashing is performed
• Very low pressure loss, also switching without stopping the installation
• The interior is made of stainless steel 316 (can also be used for salt electrolysis), seals are ozone resistant and made of Viton/PTFE
• Applicable in both a private and public installation

• Low pressure drop: Offers higher backwash velocity & efficiency than traditional 6-way valves.
• Fast switchover: The filtration pump does not have to be stopped during the switchover.
• High installation flexibility: Can be fitted directly on the filter or mounted on a wall (90° rotating connections)
• Swiss Made: High quality product providing outstanding reliability. TÜV Rheinland certified / GS mark (Tested safety).
• Very safe to operate: The valve returns automatically to "Filtration mode" in case of electrical failure.
• Adapted to all sand filters - up to 2 meters in diameter: Valves available from DN40 (50mm) to DN125 (140mm)

Besgo 5-way-valves

The Besgo 5-way valve works automatically and can be operated either by water or air pressure. A connection to the water network or a small air compressor to provide the 3.5 bars required.

To program and activate the solenoid valve, a simple 230V electric controller / timer is sufficient.

The solenoid valve receives the electrical current and opens, the incoming pressure compresses the spring inside the Besgo valve and starts the backwash process. The backwash process lasts as long as desired, as long as the solenoid valve receives electrical current. In the event of an electrical failure, the Besgo valve returns automatically to its "Filtration" position. An involuntary draining of the pool is therefore not possible.

Installation flexibility

Changing the direction of connections C and D

If the pipework is not parallel to the unit, the connection unions C and D can be rotated by 90 degrees. In addition, a fine adjustement of +/-4° is possible. This guarantees an installation free from any tension. All Besgo valves have to be glued on the outside and should always be installed with detachable connections such as screw connections or flanges. This makes service work or replacement easy.

Thanks to regular and powerful backwashes, Besgo creates the conditions for crystal clear water of the highest quality. Besgo is compatible with all types of pool water treatments including salt electrolysis systems.
