Product Description

our high-temperature low-emission packing factory specializes in manufacturing premium-grade valve packing, precision-engineered to deliver uncompromising performance for the most demanding industrial high-temperature, high-pressure applications. each meticulously crafted packing set features a five-ring configuration with precise dimensional specifications of id 52 mm × od 72 mm, engineered for seamless fit and optimal sealing contact in industrial valve stems and critical fluid-handling equipment. crafted with ultra-high-purity graphite (?99.5% purity) as the core sealing material—an elite formulation that ensures exceptional thermal stability, chemical resistance and low-emission performance—these packing sets are rigorously manufactured to meet and exceed the stringent global industry standards of api 622 and iso 15848-1, and further comply with strict ta-luft emissions regulations. this comprehensive compliance guarantees industry-leading fugitive emission control, even when operating at extreme continuous temperatures of up to 400°c, eliminating costly leakages and ensuring full alignment with environmental and safety mandates. optimized for long-term durability and reliable sealing integrity in high-temperature industrial environments, our five-ring valve packing sets deliver consistent, leak-free performance across oil and gas, petrochemical, power generation, and heavy chemical processing applications—safeguarding operational efficiency, minimizing unplanned downtime and maintenance costs, and serving as a trusted sealing solution for critical high-temperature valve systems where performance and compliance are non-negotiable.

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.
