[Wild scope of application]: Applicable ambient temperature compared with other ball valves, the stainless steel shell has a higher melting point, high-temperature resistance, resistance, waterproof and fire prevention, and is widely used. This product 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 0.2 kg is used to control the water level. [No Electricity Needed]: 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 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. [Small & Save Place]: 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. [Safe and materials]: stainless steel fully automatic water level control float valve is made of food grade material stainless steel, ensuring the safety of drinking water. With an exquisite appearance and hard shell, it has strong friction and impact resistance, effectively increasing the service life of the product.
