About us
A new stage to reinforce our specialisation
After nearly five decades dedicated to designing and manufacturing safety valves, Valnac (formerly Válvulas Nacional) begins a new stage in which its historical specialisation is further strengthened. The new structure of Xelentia Group (formerly Pekos Group) consolidates our role within the group’s industrial ecosystem, enhancing what has always set us apart: regulatory precision, technical depth and the reliability of a product designed to safeguard processes, facilities and people.
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.
An expert team dedicated to industrial protection
Our team combines innovation, technical expertise and a strong service mindset to provide a reliable response to leading companies in the most demanding sectors. We deliver specialised knowledge in each product to ensure that every valve meets precisely the safety and performance requirements of its application.
Certified quality for maximum safety
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 ISO 9001:2015 quality system. This regulatory framework, combined with decades of expertise, guarantees the production of high-performance safety valves that are consistently reliable.
Global reach and strategic alliances
In addition to the presence of our products in the Synerkos portfolio—the new commercial brand of our group—we maintain strategic alliances with leading international partners who add value to our valves through comprehensive safety solutions tailored to each customer’s specific needs.
Technology and facilities prepared for the future
Our facilities in Rubí (Barcelona), with 3,000 m² dedicated to machining, assembly and testing, incorporate CNC technology and advanced quality control systems that ensure precision and repeatability. We complement this capacity with authorised workshops that expand our production and with a new facility designed to optimise processes and increase stock, further enhancing service quality.
Since 1976 serving industrial safety
With 50 years of experience, Valnac has established itself as a European company with international recognition in the design and manufacture of safety valves for multiple industrial sectors. Throughout these decades, we have built deep technical expertise that enables us to meet the most demanding international standards and develop a unique approach based on precision, reliability and operational rigour.
This journey has brought us to where we are today: a brand with a solid track record, committed to technical excellence and guided by a clear objective: protecting industrial environments and the people who work in them through reliable, precise and high-performance safety valves.
