Graphite Packing Set for Gate Valve, ISO 15848-1, 28 * 40 mm

This Low Emission Graphite Packing Set is a high-performance sealing solution meticulously designed for gate valves that operate in critical industrial applications. Engineered to meet and exceed the stringent requirements of ISO 15848-1 and API 622, it ensures outstanding control of fugitive emissions and provides long-term sealing integrity in environments where reliability and environmental compliance are paramount. From refineries and petrochemical facilities to power generation plants and chemical processing systems, this packing set offers dependable performance under extreme operating conditions.

The packing set is manufactured from high-purity expanded graphite with a carbon content of ≥99%, ensuring superior physical and chemical properties. This premium-grade graphite material exhibits exceptional thermal conductivity, oxidation resistance, and dimensional stability, maintaining its sealing efficiency over a wide range of temperatures and pressures. It also offers excellent chemical compatibility, resisting corrosion and degradation when exposed to steam, solvents, hydrocarbons, heat transfer oils, and various other aggressive media commonly encountered in industrial processes.

The set comprises five precision-engineered rings with an inner diameter of 28 mm and an outer diameter of 40 mm, carefully designed to form a compact and resilient sealing assembly. Each ring is compression-molded and accurately sized to ensure a tight fit in the valve stuffing box, minimizing leakage paths and enhancing overall sealing effectiveness. The layered structure of expanded graphite enables the packing to retain flexibility and recovery, even after repeated thermal cycles and mechanical compression.

In addition to its superior sealing performance, the graphite packing set contributes to extended equipment lifespan and reduced maintenance frequency. Its self-lubricating nature minimizes friction and wear between the valve stem and packing surface, allowing smoother operation and preventing stem scoring. The result is a reliable, low-maintenance sealing system that helps operators reduce downtime, improve process efficiency, and achieve compliance with modern low-emission standards.

With its combination of high purity, structural precision, and verified emission control performance, this Low Emission Graphite Packing Set is an ideal choice for industries seeking a robust and environmentally responsible sealing solution that delivers both durability and peace of mind.It's important to know about Google SEO to help your website rank higher in search results.
