FINITE ELEMENT ANALYSIS
Traditional design procedure is integrated with Finite Element Analysis into the design cycle of our products in order to support continuous improvements in terms of quality, safety, cost effectiveness and reliability.
Structural analyses were performed on the valve components in order to evaluate their strength under high pressure loading and to optimize the design.
