Recently, the IP6000 Series Intelligent Valve Positioners of Boliu Control Technology (Zhejiang) Co., Ltd. successfully obtained ATEX certification from DNV. At the same time, the company’s relevant production quality system passed its audit, achieving dual compliance through product certification and production-system assessment.
From the launch of the certification project to the final issuance of the certificate, the process took nearly two years. For Boliu Control, this was not only a product-compliance certification, but also a process of reassessing its product design and manufacturing system against international standards.
Throughout the certification process, Boliu Control underwent ongoing review and verification of product design, risk assessment, type testing, technical documentation and production consistency, and implemented improvements accordingly. Through continuous alignment with applicable ATEX requirements, the company further refined product design and quality control, systematically enhancing the IP6000 Series in explosion protection safety and product reliability.
The value of high-standard certification lies not only in obtaining a certificate, but in putting the standards into practice in the product itself.
DNV Certification: Two Years of Continuous Refinement
Founded in 1864, DNV (Det Norske Veritas) is one of the world’s leading independent assurance and risk-management organizations. With more than 160 years of development, DNV operates across maritime, energy, industrial and other sectors, with operations in more than 100 countries. It has broad professional influence and credibility in international industry and is a Notified Body under the EU ATEX Directive.
ATEX (Atmosphères Explosibles) is a mandatory EU safety directive for equipment and protective systems intended for use in potentially explosive atmospheres. Products within its scope that are intended for the EU market must meet the relevant requirements for design, explosion protection, technical documentation, conformity assessment and production quality management. Meeting these requirements provides an important compliance basis for relevant explosion-protected products entering the EU market.
For Boliu Control, the IP6000 Series Intelligent Valve Positioners obtained ATEX certification following DNV’s professional evaluation and audit. This represents not only authoritative recognition of the products’ explosion-protection safety performance, but also a systematic, high-standard assessment of product design, manufacturing and quality-management systems.
Over nearly two years, Boliu Control continuously invested resources in personnel, time, testing and system development, and underwent multiple rounds of technical evaluation and audit covering both the products and the production system. From the products themselves to the manufacturing process, and from technical documentation to quality traceability, every link was required to meet the applicable certification requirements.
This process both verified the existing explosion-protection design of the IP6000 Series and examined the company’s relevant manufacturing and quality-control capabilities, while also driving Boliu Control to further improve its product-design and quality-management systems.
Intrinsic Safety and Flameproof Protection for Different Hazardous-Area Requirements
This certification covers two types of explosion-protected products in the IP6000 Series:
Benchmarking Against International Standards to Continuously Improve Product Reliability
Obtaining certification is not the end point. More importantly, certification standards must be translated into long-term, consistent quality requirements.
During the ATEX certification process, Boliu Control continuously benchmarked against the relevant requirements and further optimized the IP6000 Series in product design, material selection and reliability. In response to issues identified during certification, the company completed upgrades in three key areas:
1. Optimized PCB Design
In line with relevant ATEX certification requirements, the PCB design of the IP6000 Series was further optimized so that the products meet applicable EU technical standards in electrical design and safety performance, improving standardization and safety from the design stage.
2. Further Improved Product Reliability
For risk points that could affect long-term, stable product operation, the product structure and protective measures were optimized. Measures such as overall potting were used to strengthen protection of key components, reduce the effects of external conditions and long-term operation on internal components, lower the likelihood of faults and risk of failure, and improve operational reliability.
3. Unified Raw-Material Selection and Procurement Requirements
Boliu Control further standardized raw-material requirements. All raw materials are selected and procured in accordance with applicable EU requirements, improving product-quality consistency and stability from the material source and providing a more reliable foundation for long-term, stable product operation.
Going forward, Boliu Control will apply the design-optimization experience, reliability-improvement measures and raw-material control requirements developed through this certification to the R&D and manufacturing of the full product range, taking into account the characteristics and applicable requirements of different products.
Whether products are sold domestically or internationally, they will be manufactured to consistent high-quality requirements. By continuously improving product design, manufacturing, raw-material procurement and inspection standards, Boliu Control will put the high standards developed through international certification into every product, ensuring that every customer receives Intelligent Valve Positioners with high quality, high reliability and consistent performance.
