The valve industry is growing every day, and with this growth, more and more people are learning about the amazing opportunity to work in valves. Many new individuals entering the industry do not, however, know the first thing about valves. The first thing that should be understood is that no one learns about valves until they work with them. There is no Bachelor of Science degree for valves, and anyone involved with them had to learn from scratch at one time or another. It is, therefore, useful to have a ‘cheat sheet’, or guide, to reference for individuals entering the industry, on everything they may need to quote valves.
