Recognizing that leak-tightness is vital in high-pressure environments, at Comeval Valve Systems we are committed to technological self-sufficiency. Our facilities are fully equipped to perform in-house hydrostatic testing in accordance with the most stringent industry standards. This in-house operational capability allows us to certify the strength and leak-tightness of our valves directly, efficiently, and without intermediaries.
In-House Infrastructure for Large-Scale Challenges at Comeval
Comeval Valve Systems’ major competitive advantage lies in our centralized facilities, designed to respond quickly to technically demanding projects. We have a specialized workshop and state-of-the-art automated test benches that allow us to certify our product lines in-house in accordance with international standards such as EN 12266 and API 598.
Our in-house capabilities stand out in the market for their scope and versatility:Total flexibility and validation in our workshop
Wide range of sizes: We perform leak tests on special diameters up to DN 2600 / 104”.
Extreme pressure ranges: We subject valve bodies to extreme conditions of up to PN 420 / Class 2500.
Operational flexibility: Our in-house capabilities allow us to manage large-scale projects and high production volumes. We alternate between using automatic test benches and dynamic blind flange systems depending on the specific needs of each batch. The result is a fast and efficient response, while always maintaining full control of the process under our supervision.
Total flexibility and validation in our workshop
Conducting tests in our workshop gives us unmatched agility to adapt to each customer’s inspection point schedules. Engineering firms and industrial operators can audit the tests directly in our workshops or appoint external inspectors.
Furthermore, this in-house management allows us to immediately link each result and certificate to our digital traceability system via a QR code. By centralizing the entire inspection process at Comeval, we eliminate intermediaries, reduce response times, and provide the technical expertise demanded by the energy, chemical, and water sectors.
