Features 1、EASY TO INSTALL: This is a small float valve that is easy to install. Built in standard male threads for screwing into standard female connectors. The float valve comes with tape and 1/2Inch elbow and 1/2Inch to 3/4Inch adapter. 2、AUTO SHUT OFF: It is a kind of automatic shut off valve. When the water level reaches the control position, it will stop the water supply automatically. When the water level drops, it will automatically turn on the water, so it is a kind of fully automatic water level controller. 3、POWER SAVING: The internal float allows water to flow until a specific water level is reached. Once the water reaches this level, the float valve will be pushed up by the water due to buoyancy and stop the flow of water. When the water level starts to fall, the valve will open again and water will start flowing again, so no electricity is required. 4、WORKING WATER PRESSURE: The working water pressure of the float valve is 10psi to 150psi. If the water pressure is too low or too high, the float valve will be unsuitable for use, will not work or will be damaged. Operating temperature is between 0°C and 100°C. 5、APPLICATION: The float valve is used for outdoor fountains, courtyard fountains, rainwater tanks, swimming pools, fountain reservoirs, automatic chicken waterers, drought cattle waterers, outdoor rainwater collection barrels and so on.
