Features

 N/A Medium Pressure Valves feature:
  • Rising stem design.
  • 316SS wetted parts for excellent corrosion resistance.
  • Metal-to-metal seating achieves bubble-tight shut-off, longer stem and seat life, greater durability for repeated open and close cycles.
  • PTFE and carbon packing with metal back-up rings offers reliable stem to body sealing.
  • Non-rotating stem prevents stem to seat galling.
  • Stem sleeve and packing gland materials have been selected to achieve optimum thread cycle life and reduced handle torque. All stem sleeve threads are rolled, assuring smooth operation.
  • Safety weep holes for all pressure connections and packing area.
  • Six different valve body patterns, with choice of vee or regulating type stem tip.

Note

 N/A When selecting multiple items, the pressure rating would be that of the lowest rated component.
