  • 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.
