Overview
The Garlock 615883 compression packing is a precision valve stem sealing component designed for the 9000-EVSP Simplified packing set. The 9000-EVSP® Simplified set expands radially when the gland is tightened, creating a positive valve stem OD seal as well as stuffing box ID seal. With dimensions of 1.299ID × 1.929OD, this unit is engineered for use in demanding industrial and chemical processing environments where reliable sealing and emission control are critical.
Key Features
- Patented Cup and Cone Design: Patented “cup and cone” design permits selective component compression and controlled radial flow for effective sealing of I.D. and O.D.
- GRAPH-LOCK® Material: GRAPH-LOCK® rings of high-purity diamond texturized graphite tape, in cup and cone configuration
- Wiper Ring Protection: End rings act as wiper rings to restrict graphite particle transfer, prevent extrusion and provide extra resiliency
- Worn Valve Compatibility: The EVSP design permits a controlled radial expansion to create an effective seal against both valve stem and bore. This engineered set can be used to seal older more worn valves.
- Chemical Resistant: This Style is fire safety tested and chemical resistant.
