LET'S TALK ABOUT ANCIENT ROMAN VALVES

---

The storyline water supply within the ancient Roman Empire is grand. The transport and hydraulic charge of vast amounts of freshwater was among the factors within the immense, unparalleled success from the Roman Empire. The main Roman metropolitan areas were located, partly, within the closeness of excellent water supplies. Plentiful water improved public health insurance and permitted the urban existence to supply labor and support companies to construct the Roman economy.

Several technological accomplishments through the Roman engineers made water open to the towns. Of these accomplishments were aqueduct design, surveying, tunneling construction, lead piping, inverted siphons, lead storage tanks, and valves. Although the water was plentiful, the Roman water commissioners implemented controls to limit illegal taps and control the flow to users.

The Wright Paleohydrological Institute (WPI) continues to be studying water use within the traditional town of Pompeii. This research has incorporated using water valves to manage the flow of water towards the houses and companies inside the city.

Ancient or Modern Design?

The Romans used lead piping to distribute water to metropolitan areas and towns through the Roman Empire. Using lead piping was prevalent in the first century B.C. but for the next several centuries. Using valves to manage the flowing water during these pipeline systems seemed to be Empire wide. This universal utilization of valves and piping needed an amount of standardization that's familiar to modern engineers.

The style of ancient Roman water valves is remarkably much like today's plug valve design. Typical Pompeian water valves are proven within the figures. The valve physiques were created of bronze having a typical inline configuration as proven in Figure 1, even though the Romans also manufactured position valves with much the same construction. The valve body includes a round chamber into that the round plug was placed, as proven in Figure 2.

The valve body was welded into the lead pipe on every finish using the valve side from the union being placed into the lead pipe sleeve. Molten lead solder ended up being accustomed to weld the insert on every side from the valve. Even though the Romans had an understanding of threaded pipe, no known threaded joints were utilized on pipe or valve unions. As proven in Figures 1 and a pair of, the pipe diameter from the valve body tapered into the plug chamber, which may have led to growing water velocity along with a finer adjustment water flow.

The valve plug insert seemed to be made from bronze and it was a hollow round insert by having an oblong hole on every side of the cylinder to permit the passage water. Just like modern valves, the plug insert was rotated inside the valve body either to control the flow or provide shutoff.
