Founded in the 1950s by Tommaso Olocco, the company initially focused on plant maintenance and the construction of wooden mills and mechanical handling.

In the mid-1960s, the company passed into the hands of his son Mario Olocco, and by the late 1970s, thanks to the experience gained in the bulk material systems sector, the business began its first production of valves and mechanical components. This was a simple production of three models, produced in batches of just a few dozen pieces per year.

In the early 1990s, Olocco moved to its current industrial site in Fossano, installing its first CNC machine tools.

At the turn of the century, his children Andreana and Umberto joined the company, and remain involved in the business to this day.

Since 2015 and consistently thereafter, huge investments have been made in new production technologies and new production spaces, which continue to this day.

In October 2022, Olocco joined VDL GROEP BV, a family group of more than 100 manufacturing companies in a wide variety of applications.

The company currently produces thousands of components annually and exports them worldwide thanks to a consolidated network of customers and dealers.

VDL OLOCCO employs a 4.0 production department with state-of-the-art 4- and 5-axis multitasking machining centers, allowing us to produce medium-large production batches as well as valves made to customer specifications.

Considering the various valve families with their respective sizes and the numerous types of materials and treatments, our catalog offers over 2,000 different versions. Nevertheless, every year our R&D department focuses on new types and innovative treatments.

In our department, we design all our products with state-of-the-art 3D CAD programs and utilize technologies and software for the most demanding applications, such as those involving high temperatures.
