China Topper Valve Packing Seal Kits Co., Ltd. is a premier manufacturer specializing in high-performance industrial valves, sealing gaskets, and packing solutions tailored for the most demanding industrial applications. Our product range—including gate, globe, and ball valves—is engineered to meet stringent API standards and features advanced low-leakage graphite packing for reliable sealing under extreme pressure and temperature conditions.

We also offer a wide selection of sealing gaskets and packing materials designed to withstand chemical corrosion, thermal cycling, and mechanical stress. Each product undergoes thorough 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 certification from TüV Süd and TüV Rheinland.

Innovation drives our development. Early on, we invested in R&D focused on low-emission graphite packing to comply with the strict environmental and performance standards of markets like the United States. Our collaborations with leading universities and research institutions have enabled us to overcome complex challenges in leakage control, friction reduction, and wear resistance. This work led to our first TüV-witnessed API 622 certification and a robust portfolio of global approvals.

What sets China Topper apart is our research-driven approach to valve and sealing technology. Beyond precision manufacturing, we study material behaviors under pressure and heat, develop advanced sealing surface coatings, and analyze long-term friction and wear. Our multidisciplinary team—experts in valve design, materials science, sealing systems, and automation—works cohesively to deliver smarter, safer, and more durable solutions.

By combining cutting-edge research with practical engineering, we empower our customers to enhance safety, extend service life, and optimize operational efficiency—earning trusted partnerships worldwide.
