Fully Automatic Water Level Control Float Valve Automatic Shut-Off Mini Float Valve No Electricity Required Automatic Water Level Controller for Water Tanks and Water Towers _x000D_ How does it work? _x000D_ _x000D_ The float valve inside allows the water to flow until a specific water level is reached. Once the water level reaches this level, the float valve is pushed up by the water due to buoyancy and stops the flow. When the water level starts to drop, the valve will open again and the water will start flowing again. When the water level drops below the valve level, the float valve will automatically replenish water for your tank, water tower, livestock, or animal drinking fountain. Once it reaches the valve, it automatically stops adding water, so when the water reaches the internal float, it shuts down. [easy to install] this is a mini float valve featuring a small ball size, making it easy to install. it has a 1/2-inch male thread, utilizing bsp pipe threads. the male thread is also longer, making it a great fit for most bsp threaded connections. If your pipe thread is npt, you just need to add some ptfe tape to the external thread, then it will work perfectly as well. The ball float valve inside [no electricity required] allows water to flow until a certain water level is reached. Once the water level reaches this level, the float valve is pushed up by the water due to buoyancy and stops the flow. When the water level starts to drop, the valve will open again and the water will start flowing again, so no electricity is needed. It Is Used By People To Maintain The Water Level Of Garden Waterfalls Yardage Fountains Rain Gutters Garden Projects, It Is Used To Automatically Close Down Swimming Pools, Chicken Coops, Automatic. Chicken Water Drinkers, Cattle Watering Droughts, Outdoor Rain water Harvesting Buckets Etc. The float valve operates at a water pressure of 10 psi to 150 psi. if the water pressure is too low or too high, the float valve will be unsuitable for use and may malfunction or become damaged. Operating temperature: 0~60 degrees [easy to maintain] the float valve comes with a filter, and the filter must be used at the water inlet to avoid sand and gravel blocking the float. We use nylon as the valve body, using stainless steel screws, which will never rust and is very safe. [please note] if you are using any type of autofill float indoors, make sure you have an emergency overflow system. Herhangi bir tür otomatik dolum şamandırası zamanla arızalanabilir ve su baskınıya neden olabilir. It's a good idea to set the minimum water flow required to maintain a full water level. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
