Typical Applications
  • Instrument air lines
  • Sampling systems
  • 2-way gauge readout of line pressure
  • Manual cylinder actuation



Features & Benefits
  • Handle points to port in use or to closed position, providing a visual cue and improved safety.
  • Dyna-Pak® packing provides a leak-tight seal with low operating torque in vacuum or high pressure applications, helping to prevent fugitive emissions.
  • Dual encapsulated TFE seats and microfinished ball ensure a leak tight seal. This combination provides greater valve reliability.
  • TFE seats and washers provide excellent corrosion resistance, providing the correct material for the application.
  • A wide variety of HOKE Gyrolok® end fittings or pipe fittings provide the correct fitting option for the application.
