Features & Benefits

N/A

  • Quarter turn handle provides a visual indication on of on/off valve position, improving safety.
  • Dual encapsulated TFE seats and microfinished ball ensure a leak tight seal. This combination provides greater valve reliability.
  • Dyna-Pak® packing provides a leak-tight seal with low operating torque in vacuum or high pressure applications, helping to prevent fugitive emissions.
  • Floating ball provides pressure-assisted sealing and temperature wear compensation for longer valve cycle life and greater value.
  • A wide variety of Hoke Gyrolok® end fittings or pipe fittings provide the correct fitting option for the application.
