Graphite Packing

Forged Gate Valve Packing Set, API 622, Graphite, 85 * 65 mm

We are a professional supplier of forged gate valve packing sets, providing high-performance sealing solutions specifically designed for API 602 Class 2500 LB gate valves. Engineered for critical service conditions, our packing sets deliver long-lasting reliability in applications involving high pressure, elevated temperatures, and stringent emission requirements.

Each packing set is precision-manufactured with an outer diameter of 85 mm and an inner diameter of 65 mm, consisting of five expertly formed rings. The rings are crafted from premium expanded graphite reinforced with Inconel 600 wire, combining the flexibility and sealing efficiency of graphite with the exceptional strength, oxidation resistance, and structural stability of nickel-based alloy reinforcement. This advanced material combination ensures superior durability, low friction characteristics, and consistent performance throughout the valve’s operating life.

Our packing sets strictly comply with ISO 15848-1 and API 622, two of the leading global standards for low fugitive emission valve sealing. With proven resistance to thermal cycling, chemical exposure, and mechanical stress, they provide reliable sealing integrity and enhanced safety for demanding industrial environments such as oil and gas, petrochemical, refinery, chemical processing, and power generation facilities.

Whether for new valve assembly or maintenance replacement, our forged gate valve packing sets offer a dependable, standards-compliant solution that helps operators maintain efficiency, reduce emissions, and ensure long-term operational stability.
