Product Description

Features and Benefits:

  • High-Cycle, Live-Loaded Stem Packing
    Ensures tight seal
    Extends service life
  • 3-Piece Swing-in-Place Construction
    Easy to repair in service line
  • Made of Corrosion-Resistant 316 SS (A-351 Gr. CF8M) with 316L SS (A-351 Gr.CF3M) Weld Ends
    One valve can be used for many service conditions
  • Blow-Out-Proof Stem
    Stem is bottom loaded to prevent removal when valve is in service
  • Locking Device
    Enables plant personnel to secure valve in open or closed position when manually operated
  • Investment Cast
    Improves dimensional control and reduces porosity
  • Internal Surfaces Roll Burnished Prior to Final Polish
    Reduces surface porosity
    Improves surface finish
  • Silver Plated Nut
    Reduces galling on threads
  • Heat Treated Ferrules
    Assures continuous tight seals
The 317C Compression Ends ball valve combines tube full port construction with a variety of sanitary end connections to deliver outstanding performance in high purity applications.  The valve's uniform bore diameter and polished internal surfaces improve flow characteristics and eliminate pooling of potential contaminants.
