This valve is a replacement for traditional float ballcocks and can be applied to various high water tank systems, pools, water towers in industrial and civil construction applications. Automatic control with low self-complementary water flow; automatically stops when water is full. Features four intakes for high water volume. Sleek appearance, compact size, practical design, and simple installation. Operates without electricity, easy to use, with long service life and low failure rate, helping conserve water resources. Working pressure range: 0.2–10 kg/cm² Applicable medium: clean water Medium temperature: ≤70°C Resistance to high temperature medium: 70°C–120°C Material: Nylon PA66, stainless steel screws, food-grade rubber When the water level in the pool or tank drops, the valve body sinks, opening the pilot of the control valve. Water pressure causes the sealing surface to open, allowing water to flow. When the water level rises, the valve closes automatically. Note: If water quality is poor, proper maintenance is required. If the water filling time increases, clean the water inlet by flushing.
