- 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 srtrength 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 yeild point greater than the stem itself.
