The Company




Who we are
Nuova General Instruments S.r.l. is the flagship of the Gianesi Group, located just a few kilometers from Piacenza and nestled in the green hills of Val Tidone. With over 35 years of experience in manufacturing spring loaded safety valves, we are capable of meeting the different needs of our customers by offering products made of brass for standard applications and 316L stainless steel for corrosive environments. Our valves are available in free discharge and piped discharge configurations, making them suitable for gases, steam, and liquids used in various industries, including refrigeration, compressors, chemical, pharmaceutical, and food processing plants.
Nuova General Instruments stands for precision and reliability, with a 100% Made in Italy production that guarantees the highest quality and full traceability at every stage of the process. Our flexible production allows us to handle orders of any size, from small batches to large-scale supplies, always ensuring speed and meticulous attention to detail. Each valve undergoes strict calibration tests, conducted by two operators using certified instruments, to guarantee flawless performance. Additionally, we use only materials of Italian origin, ensuring complete traceability and an extremely rigorous quality control process.
Our commitment to excellence is demonstrated by our ISO 9001 quality system certification, obtained in 1995, and our ISO 45001 certification for occupational safety management. Our safety valves comply with the highest international standards and are certified according to European Directive 2014/68/EU (PED), ASME XIII, SELO, UKCA, Canadian Registration, ATEX, UKEX, and EAC TR CU 032/010/012. Upon request, our products can undergo testing and certification by the most prestigious certifying bodies, including INAIL, TÜV, RINA, Bureau Veritas, ABS, and Lloyd’s Register, ensuring maximum safety and reliability for any application.
Since March 2002, our headquarters has been located in a state-of-the-art facility equipped with the latest technologies, including a barcode management system for tracking every production batch, test laboratories for final inspections, automated vertical storage systems, and a single-unit packaging machine that seals each valve along with its certification and user manual. In 2017, we doubled our production and administrative space, investing in custom-designed machinery, increasing staff, and enhancing the working environment.
We have also created dedicated spaces for employee well-being, including a shaded parking area, a fully equipped conference room for international meetings, landscaped green areas for lunch breaks, and comfortable indoor spaces for relaxation and meals during the workday. The entire facility is air-conditioned and powered by photovoltaic panels, and in 2019, we joined the “Progetto Vita” initiative, installing a defibrillator inside our company to enhance workplace safety.
Nuova General Instruments perfectly combines tradition and innovation, delivering safe, reliable, and high-quality solutions to ensure the safety and efficiency of your systems worldwide.
Our History

Nuova General Instruments was set up through the entrepreneurial vision of its founder and chairman: the Cavaliere Grande Ufficiale Edilio Gianesi, born in 1926.
In 1961, after years of hard work, Gianesi, from a humble background, finally succeeded in discovering the setting in which his innate capabilities could find their fullest expression, founding Gianesi Edilio S.r.l..
During the following years there followed G.B. Impianti, RE.BI.GAS. and in 1987 Nuova General Instruments.
“My dream was to bring life back to my Val Tidone, right at a time that people were all abandoning the country to go to the cities in search of work.” (E.Gianesi)
This was the motivation behind the emergence of Gruppo Gianesi.
In a symbolic way, Nuova General Instruments represents the spirit of its founder, always growing and keeping pace with the most modern technology in order to achieve the highest standards of quality.

After the death of the Founder, Cav. Gianesi Edilio, which took place in 2013, Nuova General Instruments has maintained its corporate structure and its staff.
We boast an all-female leadership.
Albertini Patrizia, former Director of a historic company of the group for over 40 years and trusted person of the founder, partner and CEO of Nuova General Instruments since 1987.
Gianesi Barbara, grandson of the founder, after working at Gianesi Edilio srl, settled in 2010 at Nuova General Instruments srl performing various tasks: administrative, commercial and study of production processes. An intense training experience that will allow her to hold the position of CEO from 2013 onwards.
The Gianesi Family and Albertini have maintained the corporate spirit desired by the Founder but with an eye to the future, investing in new technologies, expanding the production area, duplicating the staff, creating a dedicated research and development office and expanding towards new markets thanks to the acquisition of new international approvals.
Patrizia and Barbara, assisted by a team of executives who have been working at NGI for over 20 years, represent the experience, solidity, quality and the search for innovation and development, which are the values we want to convey with our products.
