TRIM OPTIONS
6 | Fisher V500 Rotary Eccentric Plug Valve
TRIM LEVEL 4 utilizes VTC material for wear and corrosion resistance for
your most erosive applications. VTC is a Fisher trade name for a particular grade of
transformation-toughened ceramic known for being extremely rugged.
n Plug - Solid VTC or VTC surface cap
n Seat Ring - Solid VTC
n Retainer - R30006 (Alloy 6) or VTC
Typical applications for the V500 valve with trim level 4 include the dirtiest and most
erosive ows such as bauxite slurry, lime mud underow, catalyst cracker bottoms,
water with entrained solids, mineral slurries, and heavy oil slurries.
TRIM LEVEL 3 includes an Alloy 6 plug, seat ring, and retainer for erosive
services that require a metallic trim solution. It is meant for use in high-temperature,
high-velocity uids where ceramic materials are not suitable.
n Plug - R30006 (Alloy 6)
n Seat Ring - R30006 (Alloy 6)
n Retainer - R30006 (Alloy 6)
There is a high-temperature 3H conguration for applications over 316°C (600°F).
Typical applications for the V500 valve with trim level 3 include digester gas-off,
ash handling, phosphate acid, low pressure heater drains, and reclamation water.
* Some trim materials are only available with certain NPS sizes. For more information, contact your Emerson local business partner or sales ofce.
TRIM LEVEL 2 is great for general service, high-pressure applications
with an Alloy 6 plug and seat ring, and stainless steel retainer.
n Plug - R30006 (Alloy 6) or 318SST with CoCr-A faced*
n Seat Ring - Alloy 6
n Retainer - 316 SST or 17-4PH SST
Typical applications for the V500 valve with trim level 2 include soot blower,
geothermal, crude oil emulsion, and molybdenum slurry.
TRIM LEVEL 1 is for general service applications where excess wear is occuring in
the trim or body. Chrome plated plug, stainless steel seat ring, and retainer are utilized.
n Plug - 316 SST with chrome plate
n Seat Ring - 316 SST
n Retainer - 316 SST or 17-PH SST
Typical applications for the V500 valve with trim level 1 are generally standard processes
with maintenance issues due to trim wear.
APPLICATION-SPECIFIC V500 DESIGNS
Applying valves to control the extraction or separation of bitumen from oil sands is a
challenge because bitumen can be very erosive. A special V500 trim configuration is
available and ideal for use in oil sands and refining applications to withstand erosive
slurry services, helping extend operating life.
Typical applications include delayed coker heater feed valves and fluid catalytic
cracking fractionator bottoms to reactor valves. For more information about this
trim option or other available configurations, contact your Emerson local business
partner or sales office.
