What is the purpose of a bridgewall marking on a globe valve?

• A. To indicate system pressure
• B. To classify valve type
• C. To indicate the direction of flow
• D. To show temperature rating

Answer: (C)

The purpose of a bridgewall marking on a globe valve is to indicate the direction of flow. This marking helps ensure that the valve is installed correctly in the piping system, as correct flow direction is critical for the proper operation of the valve and the overall system. In certain applications, installing the valve in the wrong orientation can lead to poor performance, increased wear, or even system failure. When a globe valve has a bridgewall marking, it usually depicts an arrow or some form of symbol that clearly shows how the fluid should flow through the valve. This is especially important in systems where flow direction can significantly affect performance or where the valve operates under high pressure or specific conditions. The other choices refer to characteristics that are typically marked on valves, but they do not specifically relate to the bridgewall marking's primary purpose. System pressure, valve classification, and temperature ratings are important aspects for valve operation and selection but do not involve the flow direction, which is crucial for the functionality of a globe valve.
