1. The reversible seat is not available in every trim material. Consult your Emerson Process Management sales office.
2. The pressure or temperature limits in the referenced tables or figures, and in any applicable code limitation, should not be exceeded.
3. Ratio of maximum flow coefficient to minimum usable flow coefficient. May also be called rangeability.
Features (continued)
 Easy Installation–Integral valve body flanges mate
with many different classes of pipeline flanges,
satisfying a variety of piping requirements. Flanges
help to eliminate exposed line flange bolting,
shorten alignment and installation time, and
promote secure valve installations and piping
integrity. Flangeless valves are automatically
self-centering on line bolting for easy installation.
 Simple Assembly and Maintenance–No special
orientation, precision clamping or repetitive
centering of valve plug and seat ring is required
when tightening the retainer, promoting accurate
alignment and easy assembly.
 Improved Environmental Capabilities–The optional
ENVIRO-SEAL packing systems are designed with
very smooth shaft surfaces and live loading to
provide improved sealing. The seal of the
ENVIRO-SEAL system can restrict emissions to less
than the EPA (Environmental Protection Agency)
limit of 100 ppm (parts per million).
 Sour Service Capability–Trim and bolting materials
are available for applications handling sour service.
These materials comply with the requirements of
NACE MR0175-2002.
 Rugged Construction–Durable, solid metal or VTC
seat ring and valve plug shut off tightly without
deforming plug arms or employing thin ball seals.
Oversized shaft diameters and rugged trim parts
allow high pressure drops.
 Reliable Performance–Seat ring design (figure 2)
self-centers, self-laps, and dynamically aligns with
plug, giving excellent cycle life. Sealed metal
bearings help prevent particle buildup and valve
shaft seizure in erosive applications.
 Choice of Construction Materials–Plug, seat ring,
and retainer are available in four levels of hardness
for selection of erosion resistance.
