Product Description
The Low Emission Graphite Packing Set from our plant is designed to deliver exceptional sealing performance, durability, and environmental compliance in the most demanding industrial applications. Engineered with precision, each packing ring features an inner diameter of 65 mm and an outer diameter of 85 mm, ensuring an accurate fit and consistent compression in valve stuffing boxes. Manufactured from high-purity graphite with a minimum carbon content of 99%, this packing set provides outstanding thermal stability, chemical resistance, and low friction performance. The addition of 20% metal wire reinforcement significantly enhances structural strength, extrusion resistance, and reliability under extreme pressure and temperature conditions. Certified to withstand pressures up to 45 MPa, this packing set complies with the industry's most rigorous low-emission and safety standards, including: TA-Luft – ensuring ultra-low fugitive emissions ISO 15848 – validating sealing capability under thermal and mechanical cycling API 622 – certifying fire safety, durability, and emission performance Key advantages include: Superior low-leakage performance, supporting strict environmental regulations Enhanced mechanical strength from metal wire reinforcement Excellent thermal and chemical resistance, suitable for harsh media Long-lasting performance with reduced maintenance requirements Reliable sealing in high-pressure and high-temperature service Designed for critical industrial valves and high-integrity sealing systems, this Low Emission Graphite Packing Set ensures consistent, leak-free operation while minimizing environmental impact, making it an ideal choice for refineries, chemical plants, power stations, and other mission-critical applications.

As a leading manufacturer of industrial valves, packing, gaskets, and seal kits, Magpie Valve is a research-driven enterprise committed to advancing valve technology through material science, precision engineering, and third-party-verified performance. Our mission is to redefine the role of valves in industrial systems by focusing on the core factors that determine long-term reliability—especially sealing performance. In today’s valve industry, large-scale machining is no longer the primary challenge in China. Instead, the true obstacles lie in the mechanical behavior of non-metallic materials, advanced surface-coating processes, and the study of friction and wear mechanisms. These critical yet often overlooked areas represent the real bottlenecks to achieving high-performance, low-emission valves.
Our multidisciplinary team includes nuclear-grade sealing engineers, valve experts, materials scientists, and electromechanical specialists. By uniting academic research with practical engineering experience, we deliver high-integrity valve solutions built on scientific understanding. Magpie Valve has conducted extensive research in partnership with renowned institutions such as the National Key Laboratory of Friction at Lanzhou University of Technology, the Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics. These collaborations have enabled systematic studies of low-leakage graphite sealing technology and provided clear resolutions to the root causes of sealing failure.
Supported by rigorous testing and authoritative third-party certification, Magpie Valve has earned numerous internationally recognized credentials, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, we have tested nearly 500 valve products, including gate, globe, and ball valves, under extreme operating conditions—from 400°C to -196°C and pressures up to Class 2500 LB. These efforts not only ensure compliance with international standards but also set new benchmarks for reliability, safety, and innovation across the global valve manufacturing industry.China manufacturer offers high-quality industrial products with competitive pricing and advanced production capabilities.
