feature:Replace Polaris Zodiac G52 for spare valve for Polaris 180 280 380 480 3900Used for the anti -scanning valve of the cleaning robot of the Arctic Star Swimming PoolThis is a complete replacement kit. You only need to closely connect this product to the hose to make the swimming pool cleaner work perfectly again.Compared with the previous spare valve, we have upgraded the shell material that is more resistant to wear than before. It will not be easily damaged and the life span will double.When the pool cleaner is stuck on the obstacle or edge, it is difficult to flip. Even if the backup valve is still opened and the water no longer sprays from the nozzle, you should consider checking or replacement. The products we upgraded will avoid this situation and avoid stagnant water.It can work continuously under high water pressure, but too many sand will block gears. At this point, you need to remove the grinding wheel to clean the sand before you can continue to work.Notice:Due to different monitors and light effects, the actual color may be slightly different from the imagePlease allow 1-3mm deviations by manual measurementinclude:1 set of X swimming pool cleaning device standby valves
