Note: The product is a liquid level control valve. After installation, the float must be vertical. If installing from the top, an elbow is required to connect the float valve and the inlet line. First, fix the water inlet pipe on a horizontal surface, then connect the automatic water level control valve to the water inlet according to standard procedures. The main water inlet must align with the nominal diameter of the control valve. When in use, the shut-off valve must be fully opened. If two valves are installed in the same tank, they must be mounted at the same height. Before installation, clean all impurities from the pipeline to prevent blockage. If water quality is poor, regular maintenance of the valve is recommended. If the user notices longer refill times, flush the inlet by lifting and rinsing. Working pressure range: 0.2–10 kg/cm² (0.1–1 MPa) Applicable medium: clean water Maximum medium temperature: ≤120°C Installation type: vertical internal installation Outlet diameter: 1 inch BSP thread Working principle: When the water level in the tank or tower drops, the float inside the valve chamber sinks. This action moves the orifice rod to open the pilot orifice. When the water level rises, the float lifts and presses the lever to close the pilot orifice. Water then fills the valve chamber, causing the main valve to close. The sealing surface stops water flow immediately. Color: white Material: ABS Package contents: 1 x water level control valve Note: Color variations may occur due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
