Features and Benefits
• Compact design requires minimum
space for operation and installation.
Lower valve weight increases strength
at the process connection and reduces
gauge whip.
• Cost savings from reduced number of
components required for instrument
installation, also decreases possible
leak points.
• Easy instrument check calibration
using 1/4-inch FNPT vent/test port.
• Ball end stem eliminates seat galling,
provides bubble-tight shutoff and long
life. The hardened, non-rotating ball
ensures perfect alignment closure.
• Packing below threads prevents lubricant washout, thread corrosion, and
keeps solids from entering the thread
area, which can cause galling. It also
prevents process contamination.
• Adjustable packing adjusts easily –
loosen jam nut, tighten bushing slightly,
then retighten jam nut. Decreases
packing replacement downtime and
increases valve life.
• Safety back seating prevents stem
blowout or accidental removal while in
operation and provides a metal-tometal secondary stem seal while in the
full open position.
