Our experience and know-how

Research and Development is an important part of the company strategy and we pride ourselves in our ability to provide you with modern and effective design solutions. Depending on your needs, our engineers will work with you to design the right valve for your specific situation.

We collaborate and exchange knowledge with the most important Italian and leading University Hydraulic laboratories all over the world. Ensuring absolute quality to our products, we carry out tests on all our valves, both installed on site and on prototypes.

Design methods

The FEM (Finite Element method) is used to analyse the strength of the valve and of its components, according to the ASME code.

The CFD (Computational Fluid Dynamics) is used to check any cavitation phenomenon and the hydraulic performances of the valve, on each opening position. An acoustic simulation software is used to study the propagation of vibration and sound in the pipes, with reference to Standard EN 60534-8-4.

Nencini designs and manufactures the waterworks valves according to the ISO, DIN, ASME or AWWA standards
