How should valves in high-pressure lines be operated?

Valves in high-pressure lines should be opened and closed slowly to ensure safe operation and to reduce the risk of hydraulic shock. This careful operation helps to prevent sudden changes in pressure within the system, which can lead to damage or failure of pipes and fittings. When valves are manipulated quickly or forcefully, it can create a sudden pressure surge, known as water hammer, which can result in pipe bursts, leaks, or equipment malfunction.

Operating valves slowly allows for a gradual change in flow and pressure, which is essential for maintaining system integrity. A steady approach to adjusting the valves helps to stabilize the system and prevent abrupt fluctuations that could compromise safety and functionality.
