Increased outlet size reduces outlet fluid velocity to reduce flashing, outgassing, and cavitation damage with proper trim material selection.
Special cylinder-guided contour valve plug furnishes an equal percentage Micro-Form flow characteristic in the 12.7 to 31.8 mm (0.5 to 1.25 inch) port size and a modified parabolic flow characteristic in the 38.1 to 114.3 mm (1.5 to 4.5 inch) port size.
NPS 2x3, 3x4, 4x6, and 6x8 valves are available with either flanged or welding ends in ratings from CL150 to 1500. NPS 2x3, 3x4, and 4x6 valves are available with CL2500 rating.
ENVIRO-SEAL packing systems provide an improved stem seal to help prevent the loss of process fluid. These packing systems feature PTFE or Graphite ULF packing with live.
Connection on the side of the valve is furnished for flushing oil between liner and valve plug guide to prevent buildup of coke. An optional bonnet purge connection is also available with extension bonnet.
Tungsten carbide trim is available for the most severe conditions and may extend the life of your trim.

Applications
Typically used in the chemical and hydrocarbon industries where control of residual oils or other liquids with coking properties is necessary
The 461 features a venturi-type throat, which is useful in power plants or slurry services where high pressure drops and flashing might exist
For increased protection, the 461 valve is offered with tungsten carbide trim. Use this trim only in the most severe abrasive conditions or in moderately corrosive environments.
