Features & Benefits

N/A Safety

  • Integral bonnet provides differential thread pitch between stem threads and packing nut thread preventing accidental stem removal

    Stem tip options
  • A choice of PCTFE, metal, vee-point, blunt vee-point, or regulating stem tips

    Helps eliminate fugitive emissions
  • Dyna-Pak® packing provides a leak-tight seal with low operating torque in deep vacuum or high pressure applications

    Dependability
  • All valves are tested for bubble-tight leakage at both seat and packing

    Installation variety
  • Broad selection of male NPT, female NPT, and HOKE Gyrolok® fractional or metric tube fitting connections

    Handle options
  • Color-coded handles are available for identifying system fluids

    Panel mounting available
  • All models can be ordered for panel mounting

    Easy maintenance
  • All models can be panel mounted without packing disruption. Packing can be adjusted without removal from panel
