We design and manufacture safety valves under the Valnac Safety Valves brand, specializing in overpressure protection solutions to ensure the safety of people, equipment, and industrial processes.

Our manufacturing heritage dates back to Válvulas Nacional, a factory founded in 1976 to meet the needs of Spain’s then-emerging chemical and petrochemical industries. All our products comply with the European directives PED 2014/68/EU and ATEX 2014/34/EU and are designed and manufactured under a strict quality management system in accordance with ISO 9001:2015.
