An introduction to diaphragm check valves and how they work. Check valves come in a wide range of sizes and materials. They provide automatic flow control of liquids and gases using a variety of mechanisms. Small-bore low-pressure systems and vacuum systems make extensive use of diaphragm check valves. They are used to prevent reverse flow and the problems that could result from it. This post briefly describes how most small-bore low-pressure diaphragm check valves work. Tubing or piping about two inches in diameter or smaller are frequently referred to as small-bore. Low-pressure systems are generally understood to be about 50psi (345kPa) or less.
