Product Description

Features and Benefits:

  • Dual Pattern ISO 5211 Direct Mount Pad
    No mounting kit needed for automation
    Eliminates exposed moving parts for safer work environment
    Direct drive eliminates play and improves actuator positioning
    Dual pattern pad fits a wide range of actuator sizes

  • High-Cycle, Live Loaded Stem Packing
    Spring energized stem seals self-adjust to compensate for wear, pressure and temperature changes ensuring a leak-tight seal and extending 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 Design
    Swing-out construction makes the valve easy to repair in line

  • Universal Valve Body
    Same center section can be used for both manual and automated service

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

  • Heavy Duty Construction
  • Investment Cast
    High quality investment castings improve dimensional control and reduce porosity; certified material test reports are available upon request

  • Heavy Duty 410 SS Bolts (336 only)

The 334/336 series ball valve incorporates several innovative design features for improved process performance.  The new dual pattern ISO 5211 mounting pad facilitates direct mounting of pneumatic and electric actuators.  In combination with our high-cycle, live-loaded stem packing system, the 334/336 series ball valve provides an ideal choice for all your automation requirements.
