Both design and testing are performed by Dafram qualified engineers using dedicated software and hardware tools. Finite Element Analysis and Computational Fluid Dynamics for both structural and fluid dynamic design validation. Advanced calculation software and hardware allow to predict the valves flow characteristics in terms of pressure drop, flow velocity and risk of cavitation.
CFD analysis is the primary instrument for the design optimization: pressure and velocity fields are clearly defined at every opening angle, allowing cavitation and noise level numerical prediction.
Once known the working conditions, the single valve can be designed to perfectly meet the plant requests.
