describe Automatic float valve, water level control valve F/water tank The valve is an alternative to traditional floats and can be used in various systems such as high level water tanks, swimming pools and water towers in industrial and civil buildings. Automatic control, self-replacing water shortage, automatic water cutoff Four water outlets, large water volume Beautiful appearance, small size, convenient and simple installation No electricity required, easy operation, long service life, low failure rate, saving water resources Working pressure: 1-10 KG (0.1-1 MPa) Applicable medium: water Applicable average temperature: ≤70° Medium and high temperature resistance: 70°~120° When the water level in the pool or tank drops, the valve body sinks and the precursor of the control valve then opens. Due to the influence of water pressure in the pipeline, the sealing surface of the control valve will open. Finally the water comes out and vice versa. Notes: This product is a liquid level control valve. After installation, the float should be vertical. If top installation is required, an elbow is required to connect the float valve and inlet pipe. First, the water supply line should be fixed on a flat surface, then the automatic water level control valve should be connected to the water inlet as standard. > The main water inlet should conform to the normal diameter of the control valve. When in use, the shut-off valve must be fully open. If two valves are installed in the same basin, both valves must remain at the same level. Size: 7.1*7.67CM Package includes: 1 * float valve
