Flow size Relief valve sizing program  

FlowSize is a Windows-based program designed by Flow Safe Inc. as an aid in selecting the proper relief valve for an application.  The program allows the user to determine the required orifice flow area with a given flow capacity, fluid parameters, set pressure, and temperature, or conversely, it can determine the maximum flow capacity for a given area, pressure, and fluid conditions.  Information is provided for the complete family of Flow Safe relief valve products for gas / vapor and liquids throughout their service limits.  Sizing calculations used in the program are based on API Recommended Practice 520, Part I.
