Top Stem Bushing is retained by a stainless steel ring, provided to absorb actuator side thrust and standards or PTFE as an option

Extended neck design for all valve sizes allows for 2″ of piping insulation and provides easy access for mounting actuators

Flange Locating Holes provide quick and precise alignment during valve installation, eliminating disc interference with adjacent pipe I.D.

The seat design reduces seating/unseating torque and, at the same time, reduces wear on the contacting parts

Unique seat geometry permits lower torques and reduces seat wear

PTFE disc has 1/8″ (3 mm) minimum thickness of pure PTFE encapsulated over Stainless Steel

Resilient seat energizer extends completely around the seat, including the disc hub, providing uniform force sufficient for bubble-tight shut off
