This valve is a replacement for the traditional float ballcock and can be applied to various systems in high water tanks, pools, water towers used in industrial and civil construction. Features automatic control, low self-complementary water usage, and automatically stops when water is full. Four intake ports allow high-volume water flow. Sleek appearance, compact size, practical design, and easy installation. Operates without electricity, simple to use, long service life, low failure rate, and helps conserve water resources. When the water level in the pool or tank drops, the valve body sinks, opening the pilot of the control valve. Due to water pressure in the pipe, the sealing surface of the control valve opens, allowing water to flow. When the water level rises, the valve closes automatically. Specifications: Type: Upright Inner Installation Working pressure range: 1-10KG (0.1-1MPa) Applicable Medium: clean water Applicable Medium temperature: ≤70°C Resistance to high temperature medium: 70–120°C Outlet Diameter: G1/2 Size: 100.2 x 58 x 50mm Quantity: 2 Pieces Color: White Material: Plastic Package Contents: 2 x Water Level Control Valve Note: During installation, the float must remain vertical. If installing from the top, an elbow is required to connect the float valve to the inlet line. First, fix the feed line in a horizontal plane, then connect the automatic water level control valve to the water inlet according to standard procedures. The main water inlet should match the control valve’s nominal diameter. During operation, ensure the globe valve is fully open. If two valves are installed in the same tank, they should be positioned on the same horizontal plane. Before installation, flush the pipes to remove any debris that may cause blockage. If water quality is poor, regular maintenance is recommended. If the water filling time increases, simply disconnect the water inlet and rinse it. The package includes only the items listed above; other products are not included. Note: Lighting and monitor differences may cause slight color variations between the product image and actual item.
