  • Outlet connections in NPT or tube to 1/4".
  • Rising stem/barstock body design.
  • Non-rotating stem prevents stem/seat galling.
  • Metal-to-metal seating achieves bubble-tight shutoff, longer stem/seat life in abrasive flow, greater durability for repeated on/off cycles and excellent corrosion resistance.
  • PTFE (Teflon) encapsulated packing provides dependable stem and body sealing.
  • Stem sleeve and packing gland materials have been selected to achieve extended thread cycle life and reduced handle torque.
