304 Food Grade Stainless SteelResistance to friction and impact, effectively increasing the service life of the product. The valve body is completely made of food grade materials, which can be directly used for daily water use. When in use, 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 inductionThe bottom is designed with three-hole induction, which greatly increases the contact surface between the internal floating ball and the surface of the water. 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 lack of water. If two float valves are installed in a swimming pool, they should be kept on the same water surface Ultra-large displacementSmall and does not occupy space, it is better than the process traditional, effectively increases the water flow and has more water flow than the traditional floating ball valve. The stainless steel shell has a higher melting point, high temperature and corrosion resistance, waterproof and flame retardant, and is widely used Wide range of applicationsApplicable to various tank systems water tanks, swimming pools, industrial and civil construction water towers, etc. Without electricity, easy to operate, long service life, low failure rate, saving water resources and clean water. with pressure greater than 0.2 bus is connected to realize water level control Product InstructionsApplicable water pressure range: 0.2 - 10 kg. The product should be installed vertically on a horizontal plane, and the float valve should be down when installing. Please fix the water pipe on a flat surface first, then install the product on the water inlet pipe. When in use, the shut-off valve of this valve must be fully open. Please clean the impurities in the pipeline before installation
