Different types of valves are available. Each of these types has a number of models, each with different features and functional capabilities.
Industrial valves have been around for more than a century. As applications become more specific and complicated, valves have evolved into nine major types to suit different requirements.
The three common valve functions include stopping and starting flow, throttling (controlling) flow, and acting as a non-return check for flow (check). Industrial valves can vary greatly in size and design, but there are several basic components to valve functionality.
