Our product lineup includes gate, globe, and ball valves designed to meet rigorous API standards, featuring advanced low-leakage graphite packing to ensure outstanding performance under extreme pressure and temperature conditions.
In addition to our valves, we provide premium sealing gaskets and packing materials engineered to withstand chemical corrosion, thermal cycling, and mechanical stress. All our products undergo stringent third-party testing and hold certifications from globally recognized standards such as API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, verified by TüV SüD and TüV Rheinland.
Committed to innovation and sealing excellence, we initiated early research and development in low-emission graphite packing solutions to meet strict market requirements, particularly in the United States. Our long-standing partnerships with leading universities and research institutions have enabled us to tackle complex challenges related to valve leakage, friction, and wear. These efforts culminated in our first TüV-witnessed API 622 certification and have since expanded to a comprehensive range of international approvals, solidifying the reliability and performance of our valves in real-world applications.Learn more about Google SEO.
