Small body, large displacement: 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. No electricity/no manpower working principle: 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,and the silicone rubber The body seals the water inlet, and the valve body stops water supply. This product is used for automatic water level control of water tanks, water towers, pools, water storage tanks, solar water tanks, livestock drinking water, etc. Safe and durable 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 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. Wild scope of application: Applicable ambient temperature compared with other ball valves, the stainless steel shell has a higher melting point, high-temperature resistance, corrosion 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. type: 1/2Inch Material: Stainless steel colour: silver Package Contents: 2 x Water Level Control Float Valve Only the above package content, other products are not included.
