337C Instrumentation Ball Valve: 3-Piece Compression Ends


Product Description

Features and Benefits:

  • Made of Corrosion-Resistant 316L SS (A-351 Gr. CF3M)
    One valve can be used for many service conditions
  • ISO 5211 Direct Mount Pad
    No bracket or drive coupling needed for automation
    Eliminates exposed moving parts for safer work environment
    Improves actuator positioning and prevents side loading of the stem seal

  • High-Cycle, Live-Loaded Stem Packing
    Ensures tight seal
    Extends service life

  • O-Ring Stem Bearing
    Maintains stem alignment
    Reduces packing side loading and wear Enhances stem seal

  • Blow-Out-Proof Stem
    Stem is bottom loaded to prevent removal when valve is in service

  • 3-Piece Swing-in-Place Construction
    Easy to repair in service line

  • Locking Device
    Enables plant personnel to secure valve in open or closed position when manually operated

  • Silver Plated Nut
    Reduces galling on threads

  • Heat Treated Ferrules
    Assures continuous tight seals

The 337C Compression Ends ball valve incorporates several innovative design features for improved performance.  The valve's uniform bore diameter improves flow characteristics and eliminates pooling of potential contaminants.  Roll burnishing and polishing all 316L stainless steel internal surfaces reduces surface porosity and improves finish.  The ISO 5211 mounting pad allows for direct mounting of most actuators.
