Abstract
Check valves are used to control the amount of flow through a valve and only open when a certain pressure is reached. The path of the fluid is strictly in one direction, which allows the valve to prevent any back flow within a system. They are also one of few self-automated piping system components that do not require assistance to open or close. Some check valves use a combination spring-and-nut compression assembly to set an opening pressure. As the nut is used to set the spring compression, and by extension the opening pressure, problems tend to arise when adjusting the nut to the correct position for a corresponding pressure. The current testing methods take an extended period of time disproportional to the simplicity of the operation. The extensive process begins by hooking up hoses to check pressures and then detaching the same hoses to readjust. The cycle is repeated multiple times until the correct pressure has been confirmed three times. This can be very tedious work as some valves need to be set within a few pounds per square inch (PSI) leaving little room for error. Swagelok requested a new testing method be designed, whether it be a new process or fitting, to help reduce the testing time. This report contains the process the group underwent and the final design that was approved by Swagelok.
