Abstract
A float valve for controlling a liquid level includes a valve main body which forms a throughflow duct, a valve narrowing which is formed by the throughflow duct, and a float mounted above the valve narrowing as a valve element. The valve element is freely movable, closes the valve narrowing via its weight, and is lifted from a valve closing position via a liquid. The float has a low center of gravity so that the float always rights itself to a standing position.
