Valve manifolds are flow management devices of ever-growing interest for operators, maintainers, and design teams worldwide. Even under today\u2019s landscape of ongoing innovations, they continue to be a go-to technical solution for fluid control in systems. When two or more valves are involved, that is.\u00a0<\/strong><\/p> Since their deployment extends across diverse processes in several industries, it is only fitting to seize the opportunity to offer knowledge on them.\u00a0<\/strong><\/p> What are valve manifolds? When to use them? What configurations are available?\u00a0<\/strong><\/p> These are some of the questions to address in this introduction feature. Please, continue reading below to get the details.<\/strong><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Oftentimes comes an industrial application that calls for the setup of various valves in practically the same location. Such a specific requirement obeys a tailored configuration prepared to achieve the desired design and measurement targets.\u00a0<\/p> There are two options to tackle this process demand.<\/p> The first one is through the arrangement of a set of individual valves. A proposal that can get the job done, carrying many disadvantages to its credit. For instance, it is pricey to install and maintain. And it requires a large and bulky structure that takes up a lot of space and leaves room for many potential leak paths.<\/p> The second possibility is much simpler and overall preferred. It\u2019s the installation of a manifold. A valve manifolds!\u00a0<\/p> A manifold is a system that combines multiple valves into a single unit. A bridge between the instrument and the process. A piping segment where, internally, the valves connect in standard configurations given by a design engineer.\u00a0<\/p> The manifold is carefully assembled to allow the calibration or replacement of measuring instruments in total safety. Without having to shut down the plant! For that reason, there are different configurations available, fit for various applications.<\/p> Given how beneficial they are, valve manifolds write individual installations off the table from the get-go.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Valve manifolds fulfill critical operational functions, including:<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Because of their versatility, manifolds are a common fixture in oil & gas, petrochemical, chemical, power generation, and water and wastewater facilities. Signs are that if you are a fluid control operator for any of those industries, you have encountered a manifold along the way.\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Four major process variables are up for measurement in manifolds. They are:<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Each of these variables belong to an applied measuring instrument.<\/p> Since pressure is the most monitored variable in manifolds, it’s crucial to state the differences between the two possible reads, gauge pressure <\/strong>and differential pressure<\/strong>.\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Gauge pressure is the pressure of a system above atmospheric pressure. The value measured is zero-referenced against ambient air (or atmospheric pressure). The reading ultimately includes the pressure from the weight of the atmosphere.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t As the name suggests, differential pressure (DP) is the difference in pressure between two given points. Its value also serves as the basis to estimate other variables, such as flow rate, fluid level, viscosity, density, and temperature. Fluctuations in differential pressure tend to indicate that there\u2019s a potential problem in the process line.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t There are several design configurations available for valve manifolds. Each applies the same principle of incorporating multiple valves into a single body.<\/p> The manifold, as meant by design, is built-in with several ports that enable connections to the process, the measuring instrument, or other devices for calibration. The number and types of valves per unit are dependent on the manifold’s functionality.
