About Me
China Topper Valve Packing Seal Kits Co., Ltd. is a specialized manufacturer dedicated to delivering high-performance industrial valves, sealing gaskets, and packing solutions for the world’s most demanding applications. Our comprehensive valve lineup—including gate, globe, and ball valves—is engineered to meet rigorous API standards and features advanced low-emission graphite packing for exceptional sealing performance in extreme pressure and temperature environments.
In addition to valves, we offer a complete range of premium sealing gaskets and packing materials designed to withstand chemical corrosion, thermal cycling, and mechanical wear. All our products undergo thorough testing by independent third-party institutions and are certified to globally recognized standards, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT—verified by TüV SüD and TüV Rheinland.
Our commitment to innovation and sealing reliability sets us apart. Recognizing the growing demand for low-emission solutions, we began early R&D on high-performance graphite packing specifically tailored to the stringent requirements of global markets such as the United States. Through long-term partnerships with top universities and research institutions, we’ve tackled critical challenges related to valve leakage, friction, and durability—leading to our first TüV-witnessed API 622 certification and a robust portfolio of international approvals.
What truly distinguishes China Topper is our scientific approach to valve engineering. Beyond precision machining, we explore the in-depth behavior of non-metallic materials under stress, develop advanced sealing surface coatings, and analyze long-term friction and wear patterns. Our multidisciplinary team—spanning valve design, materials science, sealing systems, and automation—collaborates to deliver smarter, safer, and longer-lasting valve solutions.
By bridging cutting-edge research with industrial application, we empower our customers with valves and sealing products that enhance operational efficiency, improve safety, and deliver long service life. Our products have earned the trust of clients across a broad range of industries worldwide.
