This control valve packing 5800E WedgeSeal™ packing is designed for high-temperature fugitive emissions service in friction-sensitive valves.
Combining 5800 pure die-formed graphite sealing rings with the 477-1 inter-braided carbon yarn end rings from Chesterton, the control valve packing 5800E seals to low VOC* emissions levels (less than 500ppm), while providing minimal friction against the stem.
The most important feature of this design is to reduce stem friction, which ensures that the valve actuator can respond to system changes more rapidly and precisely.
