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.
