Valves are an essential component in the piping system, and ensuring that they work effectively is crucial for preventing leakage. There are various types of leakage that can occur in valves, and identifying them is vital in addressing the issue promptly.
Some of the common types of leakage in valves include internal leakage, external leakage, and stem leakage. Internal leakage happens when the valve fails to close correctly, allowing the fluid to seep through the valve. External leakage occurs when the fluid escapes from the valve and affects the surrounding environment, and stem leakage happens when the valve stem seal is not functioning correctly.
