We are a professional manufacturer and supplier of forged gate valve packing sets, providing high-performance sealing solutions specifically designed for API 602 Class 2500 LB gate valves. Each packing set features five precision-formed rings with an outer diameter of 85 mm and an inner diameter of 65 mm, engineered to deliver superior sealing reliability under extreme operating conditions.
Constructed from a high-quality combination of flexible graphite and Inconel 600 wire reinforcement, these packing sets offer exceptional durability, thermal stability, and resistance to high pressure and chemical attack. The Inconel reinforcement enhances structural integrity, while the graphite ensures excellent sealing performance and low friction, reducing wear on valve stems and extending service life.
