[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 consistent water height without manual intervention. [Versatile Sized Fittings] Equipped to handle various pipe sizes, this water tank valve accommodates 1/2-inch and 3/4-inch pipes with both side and top water inlet options. This versatility ensures compatibility with most plumbing setups, enhancing installation ease and flexibility. [Constructed from Safe, Stainless Steel] Crafted from 304 stainless steel, this auto-fill shutoff valve is safe for potable water applications. Its robust construction resists corrosion, wear, and impact, ensuring a long service life. [Efficient and Low-Maintenance] Compact and efficient, this valve delivers reliable water flow. Installation is straightforward, performance is consistent, and maintenance is minimal, thanks to an integrated filter that helps prevent sediment buildup. [Wide Application Range] Suitable for solar water heaters, livestock troughs, swimming pools, and other non-potable or potable water storage systems. This non-electric valve operates effectively at water pressures above 0.2 bar and supports water temperatures from 0°C to 100°C.
