We are a professional supplier of forged gate valve packing sets, dedicated to providing high-quality sealing solutions that meet the rigorous demands of modern industrial applications. Specifically designed for API 602 Class 2500 LB gate valves, our packing sets deliver exceptional sealing performance, mechanical strength, and long-term reliability in high-pressure and high-temperature service conditions commonly found in refineries, power plants, and petrochemical facilities.
Each packing set features a precisely engineered outer diameter of 85 mm and an inner diameter of 65 mm, ensuring a perfect fit and consistent compression within the valve stuffing box. The set is composed of five rings, meticulously manufactured from a composite of high-purity graphite and Inconel 600 wire reinforcement. This advanced material combination provides a balance of flexibility, resilience, and structural stability, allowing the packing to maintain its sealing integrity under severe thermal and pressure fluctuations.
The graphite component offers outstanding thermal conductivity, chemical resistance, and self-lubricating properties, effectively reducing stem friction and wear while preventing leakage. The Inconel 600 reinforcement enhances the mechanical strength of the packing, preventing extrusion and deformation under extreme load conditions. Together, they create a robust sealing system capable of withstanding temperatures up to 650°C and pressures exceeding 400 bar, depending on service conditions.
Our packing sets are fully tested and certified in accordance with ISO 15848-1 and API 622 standards, ensuring compliance with global low-emission requirements. These certifications verify the product’s ability to minimize fugitive emissions, contributing to safer, cleaner, and more environmentally responsible operations.It's important to know about Google SEO to help your website rank higher in search results.
