Other Valve Options
Cavitating Liquids . . . Cavitrol trim is available in
many of these valves and in other severe-service
valves. Cavitrol trim can minimize cavitation noise
and damage in a properly sized valve.
Noisy Gases . . . Whisper Trim cages can
substantially reduce noise in gas, vapor, and steam
applications. Whisper Trim is available in several
performance levels in many of these valves.
Materials for Sour Service . . . Materials and
manufacturing procedures are available for
compatibility with NACE MR0103 and MR0175/ISO
15156.
Protection Against Process Fluid Emissions . . .
Optional ENVIRO-SEAL and HIGH-SEAL packing
systems provide an improved stem seal to help
prevent the loss of valuable or hazardous process
fluids. These live-loaded systems provide longer
packing life and reliability. Live-loaded packing is
standard on GX and GX 3-way valves.
