Description: This product is small and does not take up space, and it is superior to the traditional process to effectively increase the water output, which is more than the traditional float valve. It can replace the traditional floating ball valve with stable performance and high reliability. This excellent water level control float valve is made of food grade material 304 stainless steel, which ensures the safety of drinking water. with an exquisite appearance and durable hard shell, it has strong friction and impact resistance, effectively increasing the service life of the product, and making friction in life no longer a problem. It is constructed of stainless steel material. When the water level in the water tower drops, the floating ball falls, and the pressure of the water in the water pipe is used to open the plunger with the sealing silicone surface in the valve body, the valve body starts the water supply: when the water level in the water tower rises, the floating ball floats up, and the connecting rod drives the plunger. There are 4 types for your choice: A, B, C and D. The floating ball valve is suitable for water tanks water towers/pools /water pools/solar water tanks/water storage, etc. No electricity is needed, and clean water with a pressure greater than 0.2 kg is used to control the water level.
