Food Grade 304 Stainless Steel: Friction and impact resistance, effectively increasing the service life of the product. The valve body is entirely made of food-grade materials, which can be directly used for daily water use. When using, the shut-off valve of this valve must be fully open. When installing the product, there will be water drops on the ball valve. Three-Hole Induction: The bottom is designed with three-hole induction, which greatly increases the contact area between the internal floating ball and the water surface. The floating core is designed as a solid floating ball, there is no need to worry about water leakage or insufficient buoyancy, and it is more sensitive to water shortage. If two float valves are installed in a swimming pool, they must be kept on the same water surface Ultra-large displacement: Small and space-saving, it is better than the traditional process, effectively increases the water flow, and has more water flow than the traditional floating ball
