High-Performance Control Valve Packing Set for Low Emission Applications
The China Control Valve Packing Set Supplier provides a high-quality, precision-engineered graphite packing set specifically designed for control valve applications operating under demanding conditions. Each set is manufactured using metal mesh reinforced graphite end rings and molded graphite center rings, ensuring a superior balance of sealing performance, structural strength, and long-term reliability.
Engineered in accordance with the ISO 15848-1-CC2-AH standard, this packing set meets stringent global requirements for low emission valve performance, providing proven tightness and durability even under fluctuating pressures and temperatures. It is suitable for Class 150 to Class 900 LB service, making it versatile across a wide range of industrial systems, including chemical processing, power generation, oil and gas, and refinery applications.
The reinforced graphite end rings incorporate a fine metal mesh insert that enhances mechanical integrity, prevents extrusion, and maintains stable sealing characteristics during thermal cycling. Meanwhile, the molded flexible graphite center rings deliver outstanding adaptability, ensuring excellent conformability to stem and gland surfaces. This multi-layer configuration not only minimizes leakage and emissions but also reduces friction and stem wear, supporting longer valve life and lower maintenance frequency.
The use of high-purity graphite (carbon content ≥99%) ensures exceptional thermal conductivity, oxidation resistance, and chemical compatibility, allowing the packing to withstand high temperatures and aggressive media without degradation. This material composition also enables the packing set to perform consistently under both vacuum and pressure environments, offering reliability across dynamic operating conditions.
Whether installed in control valves used for steam, hydrocarbon, or corrosive fluid regulation, this metal-reinforced graphite packing set delivers dependable performance and emission control. By combining advanced material engineering with strict manufacturing standards, the China Control Valve Packing Set Supplier offers a solution that enhances operational safety, efficiency, and environmental compliance in modern industrial sealing systems.
