As early as the 1970s, the Guichon Company has found in the chemical industry natural outlets for its fabricated constructions which enabled the former craftman’s undertaking to reach the industrial stage. The chemical sector is very demanding in reliable industrial valves to manufacture big quantities of products in large capacity plants involving huge capital spendings. Guichon Valves was able to meet this challenge in supplying a wide range of quality valves. Today, main major international chemical groups are Guichon’s clients.
