A float valve is used to shut off the flow of liquids, normally water.Our products have applied for numbers of patent protection


Float valve(also balltap or ballcock) is a mechanism or machine for filling water tanks. It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, whence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.

A discharge mechanism is activated by means of a rod or chain. As the tank water level drops, the float descends and actuates the fill valve. Water is fed to the tank to replenish its supply, and a smaller flow is directed into the overflow tube to refill the tank. Once the  valve closes, the water flow from the fill valve continues until the tank level again reaches the fill line.
