Fisherr V500 Rotary Control Valve
The Fisher V500 eccentric plug rotary control valve
controls erosive, coking, and other hard-to-handle
fluids, providing either throttling or on-off operation.
The flanged and flangeless valves feature streamlined
flow passages, rugged metal trim components, and a
self-centering seat ring (figures 1 and 2). With these
components, the V500 rotary control valve combines
globe valve ruggedness with the efficiency of a rotary
valve. Matched with a Fisher power or manual
actuator, the V500 rotary control valve dependably
controls fluids in many process industries.

NACE MR0175-2002.
Features
Resists Damage from Erosive Flow–Valve assembly
is specifically designed to combat the process of
erosion. Streamlined flow passages, rugged
components, and a wide choice of erosion-resistant
trim materials all promote long, dependable service
life in erosive applications.
Long Seat Life–Path of eccentric plug (figure 4)
minimizes contact with seat ring when opening,
reducing seat wear and friction. When the valve
plug rotates into the seat ring, a self-lapping action
occurs, improving the fit between shut-off surfaces.
Full-port, S31600, CoCr-A, or VTC seat ring has two
shutoff surfaces and can be easily reversed,
reducing downtime.

Fisher V500 Flanged Rotary Control Valve with 1061 Ac
tuator and FIELDVUEt DVC6200 Digital Valve Controller
Operational Versatility–Self-centering seat ring and
rugged plug allow forward or reverse flow with tight
shutoff in either flow direction. Reverse flow
direction helps move downstream turbulence away
from shutoff surfaces. Full 90-degree rotation
removes valve plug from flowstream, helping to
reduce plug wear. Seat ring and retainer are
available in full and restricted port constructions,
and can easily be changed if capacity requirements
change.
