[Automatic Water Level Control]This float valve uses a sophisticated design to automatically manage water levels without electricity. As the water level falls, the floating ball drops, leverages water pressure to unseal the valve, and refills the tank, maintaining water height without manual intervention. [Versatile Sized Fittings]Equipped to handle pipe sizes, our water tank valve accommodates 1/2inch and 3/4inch pipes with both side and upper water intake options. This versatility ensures a seamless fit for most plumbing setups, enhancing installation ease and flexibility. [Constructed from Safe, Stainless Steel]Crafted from 304 stainless steel, our auto fill shutoff valve secures the safety of your drinking water. Its robust construction resists friction and impacts, affording it a prolonged service life, while it remains -free, ensuring continual use without degradation. [Efficient and Maintenance-Simple]Compact and efficient, our valve outperforms traditional models in water output. Installation is straightforward, reliability is high, and maintenance low, thanks largely to an integral filter that protects against sediment, guaranteeing unimpeded operation. [Applicable in Multiple Scenarios] a range of applications such as solar water tanks, livestock troughs, and swimming pools.
