Home DAFRAM S.p.A., founded in 1956, was the first company to manufacture floating ball valves in Italy. The long experience gathered during more than 50 years of activity ensures DAFRAM is one of the most famous and competitive companies in the world. DAFRAM's factory is located in Urbisaglia (Macerata), the centre of Italy in an industrial complex covering 32.000 square meters, 12.000 of which are covered workshops. The factory consists of commercial, technical and engineering offices and of two extremely modern workshops, the latest of which, 4200 square meters, 10 meters high, completed in February 2008, allows the production, assembly, testing, sandblasting and painting of ball valves up to extremely large sizes and weights.

Due to a very large flow passage DAFRAM control ball valves can grant high flow coefficients compared to other valve types. Thanks to their operating principle, quarter-turn ball valves are able to control fluid flow at very small openings and to open at high differential pressure. They are also able to maintain low fluid velocity thus lower noise and vibration to the pipeline. In addition, control ball valves allow tight and fast shut-off in case of emergency. DAFRAM control valves assure excellent flow characteristic and provide accurate, reliable control in a wide range of applications, such as chemical, power and oil, both on gas and liquid service. 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. In order to better set the mathematical model, DAFRAM, in collaboration with 3P Engineering, has provided advanced testing equipment to test valve prototypes. A first bench was specifically designed to work with water, therefore the valve Cv can be measured as per main international standards (i.e. IEC 60534). A second loop was developed to test valves with a gaseous flow in order to evaluate sound pressure level generated in operation. DAFRAM developed a proprietary calculation software for valve sizing and valve behaviour prediction; this special tool is based on CFD calculation data and on the mathematical model validation obtained through intensive loop testing sessions that allowed a refined setting of the virtual model for each trim configuration.
