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.
