Features & Benefits

  • Class VI shut-off, Bubble tight
  • Advanced Seat Design:
    provides a bi-directional interference and pressure assisted seal. This provides maximum seal at high, medium and low pressures
  • Extended Neck:
    Allows for up to two inches of pipe insulation
  • Positive Seal Packing Design:
    PTFE is a cup and cone system and Graphite is die formed rings
  • Graphite Impregnated or Reinforced 316 SS Bearings:
    ensure long service life
  • High Strength 17-4 ph SS Stem:
    provides maximum strength for high-torque applications
  • Quick-Release Disc Design:
    reduces amount of torque needed to un-seat disc.
  • Disc Taper Pins:
    Pins are offset from the center of the stem which places them in compression rather than in sheer. This gives them a yield point greater than the stem itself.
  • Integrally Cast Disc Position Stop:
    Machined position stop on the body locates the disc in the seat to achieve maximum seat and seal life.
