Product accent：
Float valve uses a sub-valve (floating ball switch) to control the main valve. When the water level elevates to the full water level defined by sub-valve (floating ball switch), the sub-valve (floating ball switch) closes and back pressure inside the main valve accumulates rapidly, which pushes the piston valve reversibly 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.

◎At full water level, pressure accumulates in the pressure chamber and pushes the gate reversibly.		 ◎At low water level, pressure in pressure chamber dissipates, and water pressure inside the pipe pushes the gate open.
