- This automatic water level control valve is designed to regulate water level in a variety of systems, including water tanks, water towers, swimming pools, solar energy systems, toilets, water heaters, animal drinking water, air cooling systems, humidifiers, and more. Its compact size and easy installation suit many settings. - Unlike traditional float valves, this valve requires no electricity, offering ease of use and a longer service life with a low failure rate for reliable performance. - Materials: Made from materials, this valve is built to last. It can withstand a wide temperature range of 0-100°C and handle pressures from 1-12 kg. - Automatic control: The valve maintains the desired water level by regulating flow and automatically shuts off when the target level is reached, saving water and preventing overflow. - Benefits: simple installation, durable construction, energy-free operation, and consistent performance with low maintenance. - Practical use scenarios: 1) in a water storage tank or water tower to keep level steady; 2) in swimming pools or humidifiers to prevent overflow; 3) in solar energy water systems or toilets where autonomous level control is beneficial; 4) for animal drinking stations or air cooling systems requiring reliable level management.
