Business description

China Topper Valve Packing Seal Kits Co., Ltd. (https: //www.

) is a dedicated manufacturer specializing in high-performance industrial valves, sealing gaskets, and packing solutions for demanding applications.

Our valve portfolio—including gate, globe, and ball valves—is engineered to comply with stringent API standards and features advanced low-leakage graphite packing to ensure reliable operation under extreme pressure and temperature conditions.

Alongside our valves, we supply premium sealing gaskets and packing materials designed to withstand chemical corrosion, thermal cycling, and mechanical stress.

Every product undergoes rigorous third-party testing and is certified to internationally recognized standards, such as API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with verification from TüV Süd and TüV Rheinland.

With a strong commitment to innovation and sealing performance, we were among the early pioneers in developing low-emission graphite packing solutions tailored to meet the strict requirements of global markets, including the United States.

Our long-term collaborations with leading universities and research institutions have enabled us to tackle complex challenges such as valve leakage, friction, and wear.

These efforts led to our first TüV-witnessed API 622 certification and have since expanded into a comprehensive portfolio of international approvals, proving the durability and reliability of our products in real-world conditions.

What truly sets us apart is our scientific approach to valve engineering.

Beyond precision machining, we focus on understanding how non-metallic materials behave under varying pressures and temperatures, advancing coatings for sealing surfaces, and studying long-term friction and wear dynamics.

Our multidisciplinary team—spanning valve design, sealing systems, materials science, and automation—works in unison to create smarter, more durable, and more efficient valves.

By bridging academic research with industrial application, we help our customers achieve safer operations, higher efficiency, and extended service life, earning long-term trust across industries worldwide.
