Founded in 1976, Valnac (formerly Válvulas Nacional) was created to respond to the needs of Spain’s emerging chemical and petrochemical industries. Over the years, our expertise, specialization and production capacity have positioned us as a benchmark manufacturer for leading companies in sectors such as oil, refining and other auxiliary industries.
We design and manufacture safety valves strictly certified under the most relevant international standards, ensuring protection, operational precision and safe performance in the most demanding industrial environments
Technical knowledge and commitment to excellence enables us to deliver safety valves that protect processes, facilities and people in any operational environment.
In this new context, Synerkos—the group’s new commercial brand—will integrate our valves into its solutions, while Valnac continues to reinforce its position as a specialised manufacturer with international reach, expanding capabilities and raising safety standards in every project.
