Specifications: Name: Automatic Float Valve   Working pressure range: 1-10KG (0.1-1MPa) Applicable medium: clean water Applicable medium temperature: ≤70 ° High temperature medium temperature: 10 ° ~ 70 ° Type: Vertical internal installation Material: nylon + rubber In/Outlet diameter: 1/2 inch BSP external thread Size: about 4.64 x 3.07 x 2.28 inch/ 11.8 x 7.8 x 5.8 cm, For detailed pictures, please see the picture Color: as shown in the pictures Working principle:  When the surface of the water tower or the pool drops, the float in the valve chamber sinks. Use the hole rod to open the pilot hole of the control valve. Ascend, press the joystick to close the pilot hole, the valve cavity begins to fill with water, and then close the control valve. The sealing surface of the control valve immediay stops the water supply. Install tips: This product is a liquid level control valve. After installation, the float must be vertical. If you need to install from the top, you need an elbow to connect the float valve and the inlet line. First, fix the water inlet line on a horizontal surface, and then connect the automatic water level control valve to the water inlet according to the standard. The main water inlet should be aligned with the normal diameter of the control valve. When in use, the shut-off valve should be fully opened. If two valves are installed in the same tank, they should be kept in the same level. Before installation, please clean the impurities in the line to prevent blockage. If the water quality is not good, the valve needs to be properly maintained. If the user finds that the time for adding water becomes longer, he can upload the water inlet and rinse    Packing List: 1 x Water Level Control Valve 1 x Filter 1 x PTFE Tape 1 x Internal thread elbow joint (The package only includes the above items, and other products are not included.)
