What Are Isolation Valves?

Isolation valves are on-off valves, which are only in the open or closed state. Unlike on-off valves, they basically have a requirement for leakage levels. Relatively speaking, the requirements on safety are higher than on-off valves, and some parts have higher requirements on opening and closing speed. It should be said that it is a valve that emphasizes fluid separation on both sides and higher safety. Many parts without special requirements use on-off valves. ^[1]
