- The main water inlet should be aligned with the standard diameter of the control valve. During operation the shut-off valve should be fully open to ensure proper flow. - This product is a liquid level regulation valve, featuring a float-operated mechanism for automatic level control. - If multiple valves are installed in the same tank, keep them at the same height. Before installation, clean debris in the piping to prevent blockages. - After installation, the float must be vertical. If installation is from above, a connector is required to join the float valve and the inlet line. First secure the water inlet pipe on a horizontal surface, then connect the automatic water level regulation valve to the water inlet according to the standard. - Applications: in domestic water storage tanks to prevent overflow; in industrial process tanks to maintain a stable level during operation; in rainwater harvesting or cooling systems requiring automatic level regulation.
