Features Applications Model Document

A top stem bushing, retained by a stainless steel ring, is provided to absorb actuator side thrusts and is acetal as standard or PTFE as an option.
The upper stem seal serves to keep any environmental contaminants from entering the stem bore.
Bodies are two piece wafer or lug style and are epoxy coated.
PTFE impregnated steel bearings provided for precision alignment of the upper and lower stem.
The primary seal is achieved by an interference fit between the extra wide disc hubs and contoured seat.
The seat design reduces seating/unseating torque and, at the same time, reduces wear on the contacting parts.
A resilient seat energizer extends completely around the seat, including the disc hub. This provides uniform force sufficient for bubble-tight shut off.
An extended neck design in all valve sizes allows for 2" of piping insulation and provides easy access for mounting actuators..
Locating holes in the wafer version provide quick and precise alignment during valve installation eliminating disc interference with adjacent pipe I.D..
A shoulder is machined into the upper stem.
The PTFE disc has 1/8" (3 mm) minimum thickness of pure, virgin PTFE encapsulated over Stainless Steel.
