2025/04 – Nether Seal Successfully Passes ISO15848 Certification

In April 2025, Nether Seal successfully passed the fugitive emission test for RSBV products under the witness of a third party and obtained the ISO15848 certificate issued by TÜV company. This certification marks that Nether Seal has achieved internationally recognized high standards in valve low-leakage performance, signifying further international recognition of its product performance.

ISO 15848 certification is a globally acknowledged crucial standard in the valve industry and an international standard for industrial valve leakage control. It aims to ensure the reliability and safety of valves under extreme conditions, representing excellence in valve low-leakage performance, reliability, and safety. This certification is a high recognition of Nether Seal’s outstanding quality and professional competence. The certification indicates that Nether Seal has met stringent, even demanding, standards in product quality, technological innovation, and safety assurance. This is not only a moment of glory for Nether Seal but also sets a new benchmark for the industry.

With the growing awareness of safety and environmental protection, petrochemical plants are imposing increasingly stringent limits on the allowable leakage levels of toxic, flammable, and explosive media. Consequently, leakage requirements for natural gas purification facilities are even stricter, making the adoption of low-leakage valves more practical. Micro-leakage valves represent the future direction of valve development and will find increasingly widespread applications.

Through this certification, Nether Seal’s valve products have received global technical recognition, ensuring effective leakage control in high-demand industrial applications and further solidifying Nether Seal’s brand position in the international market. The completion of this certification not only enhances Nether Seal’s competitiveness in the international market but also means that our products can meet the increasingly stringent requirements of customers, especially in industries such as petroleum, petrochemicals, and coal chemicals, where strict valve leakage control is demanded.

Every success marks a new starting point. Faced with growing market demands, Nether Seal will continue to increase its R&D investment, continuously optimize its product structure and technical solutions, and strive to become a leader in the global fluid control field. In the future, Nether Seal will continuously strengthen its self-improvement efforts, endeavor to provide high-quality valve products for harsh and demanding operating conditions, and safeguard safe applications. We will continuously enhance product performance and quality, offering customers safer, more reliable, and environmentally friendly valve solutions, and creating multi-dimensional value for owners.
