Finite Element Method (FEM) Analysis for the Design and Optimization of a Cross Floating Valve for Pressure Metrology Applications

In pressure metrology, cross floating of pressure balances is used for the accurate and precise measurements of pressure. In this method, a nearly perfect balance condition is required between 2 pressure balances used in a common pressure transmission circuit, one as standard and another as device under calibration (DUC). Present paper describes the effect of stress analysis during the simulation in design, optimization and process of development of a manually actuated cross floating valve. Simulation studies have been carried out by using ANSYS software to analyze the behavior of stress, strain, and subsequent deformation. The optimization tool is used to fix all the dimensions according to factor of safety and other design points. The valve thus developed was tested in the pressure range from atmospheric to 2500 bar and the results thus obtained are found excellent.
