The Float Valve Switch for all RO Modelis used to control the level of water, at a pre-determined level in a tank/vessel. It is a mechanical device that is fitted on the inlet line to stop the flow of water into the tank/vessel. If the water is drained out from the vessel then the valve opens automatically and lets the liquid in. The inlet pipe is closed automatically once the tank gets filled and the inlet valve opens in proportion to the water level in the tank/vessel. It is of highest quality and is made using high standard material. The Float Valve Switch can be used for all RO system models .
