Perfect ReplacementThe valve replaces the traditional float valve, no electricity, easy to use, long life, low failure rate, and save water resources. Automatic ControlThe upgraded water level control valve has a patented design, fully automatic control, and the valve does not need to be driven by electricity. Automatic float valve water level control 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 4.48 x 2.95 x 2.28 inch/ 11.4 x 7.5 x 5.8 cm 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 immediately stops the water supply. Install tip: 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 pipeline 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 pipeline 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.
