[Easy to install water tank float valve] This mini float valve features a compact plastic ball for easy installation. It has a standard male thread that fits perfectly into standard female connectors. The extended male thread allows for secure tightening. The float valve comes with Teflon tape, a 1/2 inch elbow, and a 1/2 inch to 3/4 inch adapter. [Automatic water shut off valve] This float valve functions as an automatic shut-off device. When the water level reaches the preset position, the valve automatically stops the water supply. As the water level drops, the valve reopens to allow flow, providing fully automatic water level control. [No electricity required] The internal float ball enables water flow until the desired level is reached. Buoyancy lifts the float to shut off the water when the level rises, and it lowers to reopen the valve as water decreases, operating without electricity. [Working Water Pressure] This float valve operates within a water pressure range of 0.2 to 10 bars. It will not function properly if water pressure is below 0.2 bars. Working Temperature: 0100C (32212F). [Application] This float valve maintains a consistent water level with minimal variation. Ideal for use in outdoor fountains, yard fountains, rain gutter gardens, swimming pools with automatic shut-off, fountain reservoirs, automatic chicken waterers, livestock watering systems, and rainwater collection barrels.
