The DSM technology experts of the global discipline team working on technical standards in the field of instrumentation have chosen CONVAL® as the preferred software tool for sizing, calculation and optimisation of valves. They have developed a standard how to size control valves supported by CONVAL®. DSM and FIRST are working together to extend the co-operation to other applications.
