STEFFENINI VALVES was established in 1967 as generic machining shop under the leadership of Francesco Steffenini who devoted himself to the Company’s growing and development.

Francesco’s son, Paolo followed the same track drawn by his father.

Thanks to his skills and dedication he has always shown towards his work, soon STEFFENINI VALVES has grown in terms of productivity, quality and size becoming a reference point for the sector and for the industries in the area.

At the beginning of 2000, the Company underwent a strong reorganization, moving its business to other markets such as petrochemical, energy and mechanical ones. In particular, STEFFENINI VALVES developed its skills in the production of industrial pumps, flanges and valve components.

In 2014, in response to growing market demand the Company improved its specialization in the design and production of valves for the chemical and petrochemical industry.

Obviously, the concepts that have always distinguished the company took increasingly importance: Quality, flexibility and customer satisfaction.

Continuous efforts in R & D, the search for more and more qualified staff, the alternation of the old facilities with increasingly advanced machines and the passion that involves all the staff make the Steffenini Valves not only a simple supplier, but rather a reliable partner for its customers.
