Advanced Valve Technology

Abstract

The use of valves dates back some 4,000 years. When man first invented the tube or pipe to transport fluids, a method was also needed to stop and start the flow. A type of wood plug valve was used by the Chinese in early bamboo pipelines. The depths of the Mediterranean have yielded artifacts which contain fragments of petcocks dating from before the time of Christ. During the time of the Roman Empire, wooden valves were used which bore a striking resemblance to the present-day plug valves. In those ancient times, and for centuries to follow, a type of plug valve or petcock has been used. In our modern times, this same type of wooden plug valve is still in use on wine casks and beer kegs to dispense these timeless drinks.
