Liquid Filling Valves in the Bottling Industry

Liquid Filling Valve

Liquid Filling Valves

There are all kinds of operations that require some kind of heavy machining or industrial process. There is almost no heavily produced item in the world that does not work off some type of assembly line operation or some kind of mechanized action.

Certainly most people think about the automobile whenever they think of the assembly line. The automobile was a the first example of the assembly line, and no other industry has done more to revolutionize the way that the production line is moving through product. The examples of the advances in the assembly line due to the automotive industry are tremendous.

There are other industries that benefit from the advances in the production line. For one, the bottling industry needs to be able to quickly fill and cap bottles in order to turn a profit in the field. When you consider just how many bottles are produced and consumed in the United States, and the world, there is no wonder that the proper liquid filling machines that are needed to create an efficient business are at the leading edge of technologies.

One of the most essential units in order to properly fill bottles is known as a liquid filling valve. These valves are generally affixed to some type of hydraulic system that enables the process to quickly fill and move the bottles through the production line. The liquid filling valves are also known as gravity liquid fillers or pressure gravity filler. Basically, the valves are employed to fill bottles to a specific volume without error or extra time. There is no need to be concerned with overfill, as there is a mechanism that is designed to make certain that this does not take place.

In the gravity filling valves, there is nozzle that keeps the liquid in from overflow. The nozzle is placed into the open neck of the bottle, and is held in place by a centering bell. The centering bell will make contact with the rim of the bottle and this action forces the nozzle open and to thereby fill the bottle to a pre-determined level. Once the bottle has filled to a proper amount, the nozzle shuts off, and the centering bell is raised from the top of the machine, thereby making certain that no more liquid is placed into the bottle. The entire system is raised and moved through hydraulics.

      Thanks for breaking this down for us. There's a lot of info out on the bottling process, but nothing that goes into the finer detail like you have. Nice!
