China Control Valve Packing Set Supplier — High-Performance Graphite Packing Set for Control Valves

The China Control Valve Packing Set Supplier provides a high-quality sealing solution specifically engineered for control valves operating under demanding industrial conditions. This advanced graphite packing set combines precision design, premium materials, and strict adherence to international emission standards to ensure reliable, long-term sealing performance.

Product Overview

The packing set features a hybrid construction comprising metal mesh–reinforced graphite end rings and molded high-purity graphite center rings. This composite structure optimizes both mechanical strength and flexibility, ensuring stable sealing performance across a wide range of pressures and temperatures.

Complying with the ISO 15848-1 CC2-AH fugitive emission standard, the packing set is suitable for Class 150–900 LB valve applications and is ideal for use in control valves handling high-temperature, high-pressure, and corrosive media.

Key Features

• Metal Mesh–Reinforced End Rings:
  The metal mesh reinforcement provides excellent structural integrity, improving extrusion resistance and preventing packing displacement under fluctuating pressure. It also enhances heat dissipation and stability during thermal cycling.

• Molded Graphite Center Rings:
  Made from high-purity molded graphite, the center rings offer superior compressibility and resilience, maintaining consistent sealing stress even under temperature variations. This ensures excellent recovery and reduced leakage over long-term service.

• ISO 15848-1 CC2-AH Compliance:
  Fully tested to meet the requirements of ISO 15848-1 fugitive emission performance classification (Class CC2, Tightness Class AH), guaranteeing reliable low-emission sealing performance across thermal cycles and dynamic operating conditions.

• Wide Operating Range:
  Designed for Class 150–900 LB valves, this packing set performs effectively under both static and dynamic sealing conditions, covering a broad range of pressures and temperatures.

• Thermal and Chemical Resistance:
  The high-purity graphite and metal reinforcement deliver excellent resistance to oxidation, high temperatures, and corrosive process media—ensuring long-term durability even in harsh service environments.

Advantages

• Stable sealing performance under variable pressure and temperature cycles

• Superior extrusion resistance and dimensional stability

• Proven low-emission performance verified by ISO 15848-1 testing

• Excellent adaptability to control valve stem movement

• Extended service life and reduced maintenance frequency

Typical Applications

This packing set is widely used in:

• Control valves in oil and gas, petrochemical, power generation, and chemical processing industries

• Systems requiring low-emission compliance and high operational reliability

• Valves operating under high-temperature, high-pressure, or cyclic thermal load conditions

Summary

Engineered with a focus on performance, reliability, and emission control, this metal mesh–reinforced graphite packing set delivers superior sealing capability for critical control valve applications. By integrating material science with precision manufacturing, the China Control Valve Packing Set Supplier provides a robust solution that ensures safety, stability, and efficiency in modern industrial operations.
