M800 Combined Packing, Graphite Ring, API 622, Control Valve

Product Name: M800 Combined Packing
The M800 combined packing is low-emission packing designed for control valves with high-frequency switching operations. It exceeds the API 622 test standards and features dynamic detection of leakage values, providing pressure fluctuation adaptability and more stable dynamic performance.
Structure: The middle part of the sealing ring is made of high-purity die-formed graphite ring structure. The end ring uses the M602 die-formed packing.
Temperature: -200°C to +450°C in Air, +450°C in Steam
PH Range: 0-14 (excluding strong oxidizing agents)
Pressure: Up to 4,500 PSI (310 bar)
Certifications: API 622 (Second Edition) Low Emission, API 607

The API 622 test shows a dynamic leakage rate of less than 12PPM,

while the static leakage rate is less than 6PPM during the test.
