Abstract

Orbit valves are used dehydration processes of gas. Failure of valves impose cost of repair and maintenance and its experimental tests are more expensive and in many cases are not applicable. Therefore, in this work a three dimensional model of an orbit valve class 900 is created and exported to a CFD solver. Results are exported to a structural analyzer to determine the exerted forces and stresses. Analysis are considered in six position of valve ball. Results show that ball position of 45° is the critical position and probability of failure in this situation is very high. Therefore, results of 45° are valuable to design of parts and choosing appropriate material inside parts.
