At several Mediterranean towns were found small valves, all of them had similar design, such as in Rabat, Djemila, Istambul, Avarches, Augusta (where there was also found butterfly valves as taps) and Naples (were the plugs were cylindric). During the Middle Ages there were not any very important designing progresses. It was during the Renaissance when the construction of canals, irrigation systems and other hydraulic works included more sophisticated valves. Leonardo Da Vinci left good samples in his sketches. | At several Mediterranean towns were found small valves, all of them had similar design, such as in Rabat, Djemila, Istambul, Avarches, Augusta (where there was also found butterfly valves as taps) and Naples (were the plugs were cylindric).

The modern history of the valve industry starts with the Industrial Revolution. At 1705 Thomas Newcomen invented the first steam machine. It needed valves able to keep and regulate the steam at high pressure. As new inventors as James Watt created new machines, they also improve the design of the valves. But it was until many years later when the production of valves was at great scale, independently of particular projects. | The modern history of the valve industry starts with the Industrial Revolution.
