How should valves be operated in high pressure lines?

Valves in high-pressure lines should be operated slowly to ensure the safety and integrity of the system. Operating valves slowly minimizes the risk of hydraulic shock, also known as water hammer, which can occur when high-pressure fluid is quickly stopped or redirected. This phenomenon can lead to significant pressure surges in the system, potentially damaging equipment, connections, and the piping itself.

By opening or closing valves gradually, pressure changes within the line can be managed more effectively, allowing the system to adjust and reducing the likelihood of sudden fluctuations that might cause harm. This careful operation is critical in maintaining the overall performance and longevity of high-pressure systems. It also helps ensure that the flow remains stable and controlled, which is essential for consistent operation in various applications, such as water distribution and industrial processes.
