FLOAT VALVE Float valve uses a sub-valve (floating ball switch) to control the main valve. When the water level elevates to the full water level set by sub-valve (floating ball switch), the sub-valve (floating ball switch) closes and the back pressure chamber inside the main valve accumulates pressure rapidly, which reversely pushes the piston valve to close. By this mechanism, the float valve can thus control the water level. In order to save space inside the pool and for easy maintenance, it is recommended to install the float valve outside the pool. [Float valve closed state] [ Float valve open state] ©At full water level, pressure accumulates in ©At low water level, pressure in pressure chamber the pressure chamber and pushes the gate dissipates, and water pressure inside the pipe pushes reversibly. the gate open. ► The working pressure should be greater than 0.3 kgffcm2, please check the pressure before installation. ► Please remove impurities or metal dusts inside the pipe thoroughly. If possible, please add filter to prevent pipe blocking. ► Vertical and horizontal installation is acceptable. Avoid upside-down installation under insufficient flow. ► Please uses high pressure float ball switch. Flow Chart of Float Valve Flow rate-Water
