Graphite Packing

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

This Low Emission Graphite Packing Set is specifically engineered to deliver exceptional sealing performance in gate valves operating under demanding industrial conditions. Designed to comply with stringent global fugitive-emission standards—including ISO 15848-1 and API 622—it provides a highly reliable solution for applications where emission control, durability, and long-term stability are critical.

Manufactured using high-purity expanded graphite with a carbon content of ≥99%, the packing set offers outstanding thermal conductivity, chemical inertness, and resistance to oxidation. These material properties enable the packing to maintain structural integrity and sealing efficiency across a wide temperature and pressure range, even under frequent thermal cycling or exposure to aggressive process media.

The set consists of five precision-molded rings with a 28 mm inner diameter and 40 mm outer diameter, ensuring a snug and uniform fit around the valve stem. The rings exhibit low friction characteristics, reducing stem wear and allowing smooth valve operation while maintaining tight sealing performance. Their engineered density and resilience help minimize fugitive emissions by preventing leakage pathways from forming over time.

This combination of high-purity materials, robust construction, and compliance with leading industry standards makes the Low Emission Graphite Packing Set an ideal choice for refineries, petrochemical plants, power generation facilities, chemical processing systems, and other environments where reliable valve sealing is essential for safety, environmental protection, and operational efficiency.
