Automatic Float Valve, Swimming Pool Automatic Filling Float Valve - Automatic Water Level Controller for Water Tank

【Automatic Operation】The float valve automatically fills water tanks, water towers, animal and livestock waterers when the water level is lower than the valve. It automatically stops filling once the water level reaches the valve level and closes when the water level reaches the internal float.【Easy to Install】This mini float valve features a compact ball, easy to install. Its external thread is 1/2 inch and it is compatible with most BSP threaded fittings. If your thread is NPT, simply add PTFE tape to it for optimal operation. 【No Power Supply Required】Built-in float valve allows water to flow up to a specific level. Once this level is reached, the float valve is pushed upward by the water using buoyancy, stopping the flow.When the water level drops, the valve opens again and water starts flowing again. So no power supply is required.【Widely used】It is used to maintain the water level of garden waterfalls, courtyard fountains, garden gutters, for automatic closing of swimming pools, chicken coops, automatic chicken waterers, etc. It is suitable for livestock watering in dry areas, outdoor rainwater harvesters, etc.【Working Water Pressure】The working water pressure of the float valve is between 10 and 150 psi. Too low or too high water pressure can cause the float valve to become unusable, inoperative, or damaged.Operating temperature: 0°C to 100°C.【Easy maintenance】The float valve comes with a filter, which must be installed at the water inlet to prevent sand and stones from blocking it. Safety and environmental friendliness: The valve body and screws are made of stainless steel, a material that does not rust and is very safe. Tips: If using an automatic water fill float indoors, make sure an emergency overflow system is installed. Any automatic water fill float can fail and cause flooding. It is best to set the water flow to minimum to maintain an optimal water level.
