Guichon Valves specialises in the engineering, manufacture, assembly and testing of cutting-edge industrial valves ( For more than 90 years, Guichon Valves has capitalised on the added value of its products, the technical expertise of its employees and the reputation of the Guichon Valves brand around the world.


Since its acquisition in February 2014 by the funds managed by Argos Wityu, Valco Group France has developed internationally through the opening of numerous subsidiaries and sales outlets. This merger with Guichon Valves is a highly strategic move, aiming at expanding the range of products and offering customers bespoke technology and services and addressing complementary markets (pharmaceuticals, fine chemicals and naval armaments).

After 10 years of growth, we are looking for support from a major French industrial company in the sector to increase the commercial clout of Guichon Valves and reinforce its credibility among customers which are often 1000 times bigger than us,” says Thierry Perrier, Chairman of Guichon Valves.

Valco Group France has also opened up its capital to FDEN (Fonds de Développements des Entreprises Nucléaires).

The role of FDEN – which is managed by Bpifrance and supported by industrial companies in the nuclear sector (EDF, Areva, GE-Alstom, Vinci and Eiffage) – is to support the new group with its development plans and provide the management team with its nuclear expertise and know-how.

Jacques Solleau, Director of FDEN, says, “By giving Valco Group the resources to grow, FDEN intends to offer the nuclear sector a solid and competitive French specialist in nuclear valves. The Valco Group, with its engineering offices and range of specific products, is now able to support development in the sector both in France and abroad.”

Stéphane Galichet, Managing Director of Valco Group France, adds, “These two very separate operations (the merger with Guichon Valves and opening the group’s capital to FDEN) allow Valco to enter a new phase. In relation to Guichon Valves, the complementarity of products and international sites will make the new group a major player at a global level in technical and special valves, as well as in critical industrial processes. Welcoming FDEN as a shareholder will allow the group to develop in-depth knowledge in the nuclear field and improve its response to the largest customers. ”

This is a new phase in the development of Valco Group France. These two operations fit perfectly with Argos Wityu’s investment philosophy, which is designed to support managers and accelerate development within companies – a strategy implemented by the management team over the last two years, particularly by opening new sites abroad and strengthening the team, “says Gilles Mougenot, Chairman of Argos Wityu.
