Valves are one of the most important components of fluid based industrial systems. From controlling fluid flow to regulating the pressure, these valves perform a variety of functions.
In accordance with their usage, these valves come with several different configurations. Most prominently, pneumatic check valves, high pressure needle valves, ball valves, toggle valves and purge valves are used.
In certain conditions, two or more different requirements have to be fulfilled. This necessitates use of two or more valves at a single location in the system. However, this can be inefficient since it takes double the space.
