STYLE 9000 EVSP*
(EXPANDABLE VALVE STEM PACKING)
The 9000 EVSP set combines three superior Garlock products - Style 98 carbon packing, GRAPH-LOCK® die-formed rings, and aluminum gaskets (spacers) - to prevent any system emission (gas or liquid) via a valve stem. The nearly chemically inert set expands radially when the gland is tightened for a positive valve stem OD seal as well as stuffing box ID seal. A patented “cup and cone” configuration uses selective component compression to ensure a tight seal. The Style 9000 EVSP set is extremely useful in hydrocarbon industry processing, or any valve application where elimination of encrustation, chemical attack, or health hazard is required.
