Float Valve

A float valve, also known as a ball valve or float-operated valve, is a mechanical device used to control the level of liquids in tanks or reservoirs. It consists of a valve mechanism connected to a floating ball or float that rises and falls with the liquid level. The key components of a float valve include the float, the valve body, and an inlet orifice.
