Features and advantages
Class VI is closed, bubble is tight
Advanced seat design:
Provides two-way interference and pressure-assisted sealing. This provides maximum sealing at high, medium and low pressures
Extend the neck:
Allow up to two inches of pipe insulation
Positive seal packaging design:
PTFE is a cup and cone system, and graphite is the ring formed by the mold.
Graphite impregnated or reinforced 316 SS bearings:
Ensure long service life
High-intensity 17-4 ph SS stem:
Maximum strength for high torque applications
Quick release design:
Reduce the amount of torque required to remove the disc.
The pins are offset from the center of the rod so that they are in a compressed state rather than a transparent state. This makes them bigger than the stem itself.
The overall casting plate position stops:
The machined position stop on the fuselage positions the valve disc in the seat for maximum seat and seal life.
