pplicable ambient temperature compared with other ball valves, the stainless steel shell has a higher melting point, high-temperature resistance, resistance, waterproof and fire prevention, and is widely used. stainless steel fully automatic water level control float valve is made of food grade material stainless steel, ensuring the safety of drinking water. With an exquisite appearance and hard shell, it has strong friction and impact resistance, effectively increasing the service life of the product, and making friction in life no longer a problem. This product is small and does not take up space, and it is superior to the traditional process to effectively increase the water output, which is A ball float valve inside allows water to until a specific level is reached. Once the water reaches this level, the float valve be pushed up with water due to buoyancy and stop the of water. When the water level starts dropping, the valve open again, and the water to again, so no need electricity. The float valve comes with filter, the filter must be used in the water inlet, avoid sand and stone blocking the floating ball.We used stainless steel as the valve body, used stainless steel screw, never rust, very safe. This product is suitable for water tanks water towers/pools /water pools/solar water tanks/water storage, etc. No electricity is needed, and clean water with a pressure 0.2 kg is used to control the water level, Weight: 1.17065461122 Pounds, Manufacturer: HWIREUIGT
