About Tognella Valves
Tognella Valves is a world leader in design, production and distribution of hydraulic check and regulation components and valves, claiming the certification of its own Quality System in accordance with EN ISO 9001:2015 Standards.
Tognella S.p.a. history dates back to the last century, with two brothers Vittorino and Dorino Tognella who in 1957 decided to combine their technical experience and to establish “ F.lli Tognella Sdf “.
The challenge of that time, taken by the two Tognella brothers, was the one of manufacturing high quality products at a right price. This meant working in competition with international giants, but simplicity, rigour and wise administration permitted to that little company to become, during time, one of the main character on the national market. But it is during 80’s that consecration at international level arrives for Tognella S.p.a., that is now able to face the real world leaders in the field.
From the 90’s up to today
In 1992 the sons of Vittorino and Dorino Tognella take over the management: Ferruccio, Luigi and Fabio. The three of them have taken up the challenge, carrying on the work their parents begun, with the same tenacity.
During these years the process of internationalization of the company begins spending time on fairs and travels searching for trading strategies necessary to state the trademark “ FT “ in the foreign market. The purchase of the new headquarter office in Somma Lombardo, the current seat of F.lli Tognella Spa, allows the union of all craftsmen in a single plant.
The following step in 2000 has been the transformation from a single company to Tognella Group, result of synergies from the union of different firms: Sesino S.p.a., Lametars 2005 S.r.l., Special Service Seprio S.r.l., Tecnovi S.r.l. and National System S.r.l. Today Tognella Spa is a leader in hydraulic valves production for every kind of application; flow regulation, cartridge flow control, single-acting control valves, Cetop, stackable and solenoid valves.
The product combined with the service for a result of “global“ excellence. We are a product firm with a strong calling to service, specialized in production of hydraulic valves and components. We provide turnkey solutions of real quality, efficient in their function and functionality, both for standard and customized, to match and rise in an increasingly competitive and global market. But not only: we create positive experiences, lasting human relationships and cooperations finding their natural union into the wide product range offered on the market; products that stand out, for more than 60 years, in control and regulation fluid scene through their complete reliability.
In our company we follow the safety and hygiene protocols required by the regulations. From the production to the packages that we will ship to you, everything is sanitized and does not come into contact with operators without protection instruments.
