The packing used in cast steel valves is the M800 series graphite packing,
with a graphite carbon content exceeding 99% and a sulfur content below 50 PPM.
The dynamic leakage rate, as tested according to API 622, is less than 12 PPM.
The static leakage rate is below 6 PPM.
All the gaskets used are low-emission gaskets certified by TÜV Rheinland TA-LUFT
