【Auto function】MEUPMEOP the float valve automatically refills water for your water tank,water tower,livestock,animal water drinker when water drops below the valve level. Once it reaches the valve, it would automatically stop refilling water,so it will shut-off when the water reaches the internal float.

【Easy to install】It's a mini float valve,MEUPMEOP branded ball size is small,so easy to install,the male thread is 1/2", we used BSP pipe thread,also the male thread is longer,it's perfectly to fit most of BSP thread connections. If your pipe thread is NPT,you just need to add a few PTFE TAPES on the male thread,then it works perfectly as well.

【No electricity needed】A ball float valve inside allows water to flow until a specific level is reached. Once the water reaches this level, the float valve will be pushed up with water due to buoyancy and stop the flow of water. When the water level starts dropping, the valve will open again, and the water will start to flow again,so no need electricity.

The valve is made of brass and the float is made of stainless steel. It is corrosion resistant, ductile at high temperature and has low magnetic permeability.
