This product is compact and space-saving, designed to effectively increase water flow compared to traditional float valves. It offers stable performance and high reliability, serving as a replacement for conventional floating ball valves. This water level control float valve is made of food-grade 304 stainless steel, ensuring the safety of drinking water. It features a durable hard shell with excellent resistance to friction and impact, enhancing the product's longevity. Constructed from stainless steel, the valve operates automatically. When the water level in the tank drops, the float descends, allowing water pressure to open the plunger with a silicone sealing surface inside the valve body, initiating water supply. As the water level rises, the float lifts, and the connecting rod actuates the plunger to stop the flow. Available in four types: A, B, C, and D. Suitable for use in water tanks, water towers, pools, solar water tanks, and water storage systems. No electricity requiredoperates with clean water at pressure greater than 0.2 kg to control water level automatically.
