FEA Case Study

Design Optimization of Gate Valve Body for High Pressure Fluid Flow Applications, USA

The Client
Design, USA

The Objective

To perform design optimization of gate valve used for high pressure fluid flow application.

The Solution

The gate valve design was first analyzed as per the given loading conditions to measure the stress and deformation values across the geometry. To reduce the deformation value to an acceptable limit, the valve geometry was re-modeled with an additional rib on the outer surface. The following structural analysis for the new design showed considerable reduction in deformation values.

ANSYS Professional NLS 14.5


Engineering Solution

The existing valve body was first analyzed under given operating conditions to identify stress concentration regions. It was observed that the deformation values across the geometry were exceeding the permissible limits. The structural analysis also helped in figuring out the material’s factor of safety across the geometry.

The new body design was suggested based on the analysis results by applying ribs, thereby providing additional structural strength to the valve. The subsequent structural analysis performed for the new design showed beneficial results, reducing the deformation below the specified limit.
