 Application Versatility–Standard construction
materials and seal assemblies provide long life and
outstanding performance in a broad range of liquid
and gas applications.
 Easy Installation–The valve body self-centers on the
line flange bolts as a fast, accurate means of
centering the valve in the pipeline.
 Reliable Flange Gasketing Surface–Seal retainer
screws are located so there is no interference with
the sealing function of either flat sheet or spiral
wound line flange gaskets.
 Powder paint as standard– The Emerson Process
Managementt powder paint finish offers an
excellent corrosion-resistant finish to all steel parts.
 Excellent Emissions Capabilities– The optional
ENVIRO-SEALt packing systems, are designed with
very smooth shaft surfaces and live-loading to
provide improved sealing, guiding, and loading
force transmission. The seal of the ENVIRO-SEAL
system can control emissions to below 100 ppm
(parts per million).
