What are Instrumentation Valves?

What are the Most Common Instrumentation Valves Available?

As Wikipedia defines it-

“A valve is known as a device that helps in controlling the passage of fluid through a pipe or duct, especially an automatic device allowing movement in one direction only.”

Thus, basically, valves serve to regulate the flow of gases, liquids or any other loose materials through a piping system. This is done through by controlling the opening and closing of apertures or obstructing the ports.
