TS308-AV-6 Low emission valve stem packing
Structure description:
TS308-AV-6 is made of special graphite with inconel wire mesh reinforced braided packing ring which with rectangular cross section.
The unique design and manufacture to make the TS308-AV-6 has optimal sealability after installed in the stuffing box, there is no leakage after thousands movements of valve stem, even keep stable function under the high pressure and temperature. To use the special graphite brings the understanding features of low emission, low friction and abrasion resistant. It prolongs the longer life span of packing to compare with normal packing.
Application:
It applies to the Gate valves, isolating valves, control valves, global valves for the industries of petrochemical, chemical engineering, nuclear power plant, anti-corrosion equipments and so on.
