INCREASE AVAILABILITY WITH THE FISHER V500 ASSEMBLY
Body Construction Options
Full and restricted port trims for
variable-flow applications provide
operational versatility. Optional internal
body coatings help withstand erosion
and promote extended life. The V500
flanged body helps eliminate exposed
line flange bolting, shorten alignment
and installation time, and promote
secure valve installations and piping
integrity. The flangeless V500 body is
self-centering on line bolting for easy
installation.
Emissions Control
Available Fisher ENVIRO-SEAL
™
packing
system provides improved sealing
and control of emissions compared to
standard packing.
4 | Fisher V500 Rotary Eccentric Plug Valve
Reliable Actuator Performance
The 2052 spring-and-diaphragm actuator
was designed for long operating life
under load conditions. It has no O-rings
to wear, inherent fail position on loss of
air, low actuator pressures for operation,
and double-sided diaphragms.
Precise Valve Positioning
The linkage-less, non-contact FIELDVUE
DVC6200 digital valve controller is paired
with the V500 valve to achieve precise
positioning and fast response to process
changes. With no linkage to wear,
loosen, corrode, or vibrate, the FIELDVUE
DVC6200 digital valve controller can
handle harsh environments and nonstop
cycling. It offers integral 4-20 mA
position feedback for explosion-proof or
non-explosion-proof applications.
Rugged Construction
Eccentric plug action
minimizes friction and seal
wear. Durable metal or very
tough ceramic (VTC) seat ring
and valve plug shut off tightly
without deforming plug arms
or employing thin ball seals.
Selectable Trim
You can select trim materials for various
erosive applications. The plug, seat ring, and
retainer are available in four levels for a
range of erosion resistance. See pages 6–7
for trim level details.
Large Pressure Drop Without Windup
The large diameter, splined shaft with
clamped actuator lever connection helps
prevent lost motion while minimizing
windup and allowing for large pressure
drops. This configuration is ideal for
accurate positioning and throttling control.
Bearing Options
Sealed metal bearings help prevent
particle buildup and valve shaft
seizure in erosive applications.
High-temperature bearings
are also available.
Compact, High-Torque,
Spring-and-Diaphragm Actuator
The 2052 actuator allows greater
mounting versatility where space is
at a premium.
