[Stainless Steel Water Float Valve, No Electricity Required]: The stainless steel automatic water level control float valve is made of food-grade 304 stainless steel, ensuring water safety. This float valve features an elegant appearance, a durable shell, and strong resistance to friction and impact. The water level float sub-valve works with an automatic water level ball valve to control water levels without electricity.[Full-Automatic Water Level Control Float Valve]: When the water level drops, water pressure in the pipe opens the silicone seal inside the valve body, allowing water to flow in. When the water level rises, the float ball rises and uses water pressure to close the silicone sealing valve on the plunger, stopping water supply automatically.[Connects to 1/2 inch, 3/4 inch, and 1 inch Water Pipes, Easy to Install]: These float valves are compatible with 1/2 inch, 3/4 inch, and 1 inch water pipes for top or side water inlet applications. Two installation methods: with or without elbows. The 1/2 inch float valve can directly connect to a 1/2 inch pipe. Alternatively, use the included adapter to connect 1/2 inch to 3/4 inch or 1 inch pipes.[Wide Application Range]: The compact automatic water level control valve saves space and ensures efficient water flow.
