The Hard-Seal Ball Valve Packing Set Plant delivers a premium sealing solution purpose-built for the rigorous demands of high-pressure hard-seal ball valves—a product that combines precision craftsmanship, low-emission performance, and uncompromising durability for industrial applications where reliability is non-negotiable.

Meticulously manufactured to exact dimensional specifications of inner diameter (ID) 50 mm × outer diameter (OD) 60 mm, this packing set is engineered for a seamless, gap-free fit within hard-seal ball valve assemblies. Each set comprises 8 precisely formed rings, ensuring uniform compression and consistent sealing contact across the valve stem—eliminating the risk of leak paths that can arise from ill-fitting or irregular packing components.

At the core of its exceptional performance is a material formulation that prioritizes quality and longevity: every ring is crafted with a minimum 99% graphite purity. This ultra-high-purity graphite delivers unparalleled chemical inertness, thermal stability, and lubricity, enabling the packing set to withstand aggressive media, extreme temperature fluctuations, and the constant friction of valve stem operation without degradation. The result is a sealing solution that maintains its structural integrity over extended service cycles, reducing the need for frequent maintenance and minimizing unplanned downtime.

Designed with low-emission performance as a core attribute, this packing set meets the stringent environmental and operational standards demanded by modern industrial facilities. It excels in high-pressure operating conditions, forming a robust, leak-tight seal that prevents fugitive emissions of hazardous gases, fluids, or vapors—critical for compliance with global emission regulations and for safeguarding workplace safety.

Ideal for deployment across sectors such as oil and gas exploration and refining, petrochemical processing, power generation, and chemical manufacturing, this packing set is the go-to choice for hard-seal ball valves in critical service applications. Whether for new valve installations, retrofitting legacy systems, or routine maintenance overhauls, it provides plant operators with the confidence that their sealing systems will perform reliably under the most challenging conditions.
