Product Description
our large-diameter butterfly valve packing set is precision-engineered to deliver ultra-reliable, leak-tight sealing for high-performance butterfly valve systems in demanding industrial operations. specially dimensioned at an inner diameter of 170 mm and outer diameter of 186 mm, this packing set is expertly constructed from high-purity anti-oxidation graphite—formulated to resist thermal degradation—and robustly reinforced with braided inconel 600 wire, a premium alloy that elevates its thermal resistance and mechanical strength to withstand extreme temperature fluctuations and high-pressure operating conditions. manufactured to adhere to the stringent global standards of iso 15848-1 and api 622, this packing set not only guarantees industry-leading low fugitive emissions but also delivers an extended service life, minimizing the need for frequent replacement and reducing unplanned operational downtime. its optimized design and high-performance material composition make it the definitive sealing solution for critical service butterfly valves across the oil and gas, petrochemical, power generation, and heavy chemical processing industries, where sealing integrity directly safeguards operational safety, environmental compliance, and long-term system efficiency.

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.
