[Stainless Steel Water Floating Valve, No Electricity Required]: The stainless steel automatic water level control floating valve is made of food-grade 304 stainless steel, ensuring water safety. This water floating valve features an exquisite appearance, a hard and durable shell, and strong resistance to friction and impact. The water level floating sub-valve with an automatic water level ball valve enables water level control without electricity.[Full-Automatic Water Level Control Floating Valve]: When the water level drops and the float ball descends, water pressure in the pipe opens the silicone seal inside the valve body, allowing water to flow. As the water level rises, the float ball lifts, causing the plunger to compress the silicone seal, shutting off the water supply automatically.[Connects to 1/2 inch, 3/4 inch, and 1 inch Water Pipes, Easy to Install]: These floating valves are compatible with 1/2 inch, 3/4 inch, and 1 inch water pipes for top or side water inlet applications. Two installation options: with or without elbows. The 1/2 inch valve can directly connect to a 1/2 inch pipe, or use the included 1/2 inch to 3/4 inch adapter to connect to a 3/4 inch pipe.[Wide Application Scope]: The compact design of the automatic water level control valve saves space and effectively improves water flow efficiency. It is compatible with most standard thread connections. This 304 stainless steel fully automatic floating valve is ideal for use in water tanks, swimming pools, ponds, and automatic animal watering systems.[Packaging]: The automatic water level control valve kit includes 7 accessories: one 1/2 inch water level control valve, one 1/2 inch to 3/4 inch adapter, and one 1/2 inch female coupling.
