5800 WedgeSeal™ Packing
Chesterton 5800 WedgeSeal™ Packing sets are manufactured from high-purity graphite. The die-formed rings are non-absorbent and non-wicking. A corrosion inhibitor is incorporated into the rings to help prevent stem pitting. At elevated system pressures, Chesterton 5800 reduces stem friction while sealing effectively. It provides critical control valves with limited load capabilities to respond more rapidly and precisely throughout the pressure range.
•High technology solution for modulated, actuated valves
•Reduced stem friction; lower actuation force needed
•Passes API 589 Fire Test
•Certifiable for nuclear service
