Fisherr 8580 Rotary Valve

The Fisher 8580 rotary valve offers excellent throttling
performance. An approximately linear flow
characteristic provides precise throttling control. The
8580 valve offers high cycle life and rugged reliability.

The valve body meets PN 10 through PN 40, CL150,
and CL300 ratings. Face-to-face dimensions meet EN
558, API 609, and MSS-SP68 standards. Line centering
clips provide for versatility to mount and align the
same wafer style valve body in different piping
configurations (ASME and EN ratings).

The 8580 rotary valve features an eccentrically­mounted disk with either soft or metal seal, providing
capability for enhanced shutoff. The interchangeable
sealing technology allows for the same valve body to
accept both soft and metal seals.

The actuator sizing and selection process is improved
by simply reading a table for information.

WAFER STYLE

8580 Features

 Approximately linear flow characteristic– An

approximately linear flow characteristic provides
precise throttling control.

 Global Standards– The valve meets API, ASME, and

EN standards, making it suitable for use in all world
areas.

 PEEK/PTFE bearing as standard– The PTFE-lined

PEEK bearing is a low friction, low wear bearing. It
allows the valve to operate under high pressure
drops for a high cycle life while maintaining low
torque. The “drop-in” bearing design enables fast,
easy maintenance.

 Spline-ended Shaft– The splined shaft with clamped

lever and single-pivot linkage reduces lost motion
between the actuator and the valve shaft.

W9498-2

 Improved shaft-disk pinning– The improved

expansion pin system ensures there is a positive,
durable connection between disk and shaft. This
connection reduces backlash and wear in the drive
system, optimizing long-term performance. It also
makes disassembly for maintenance quick and
simple with no need for special tools.

 New Spring-Loaded Shaft– The spring in the

outboard shaft provides support to the drive train
and disk, enabling the shaft to be installed in both
horizontal and vertical orientations with no
detriment to performance or cycle life. This
complements the ability to mount the actuator on
the left- or right-hand side, enabling access for any
installation.

 Excellent Emissions Capabilities– The optional

ENVIRO-SEALt packing systems, are designed with
very smooth shaft surfaces and live-loading to
provide improved sealing, guiding, and loading
force transmission. The seal of the ENVIRO-SEAL
system can control emissions to below 100 ppm
(parts per million).

 Sour Service Capability– Trim and bolting materials

are available for applications involving sour liquids
and gases. These constructions comply with NACE
MR0175-2002, MR0103, and MR0175 / ISO 15156.

 Field-Reversible Valve Action– The actuator/valve

assembly action can be converted from
push-down-to-open to push-down-to-close, or vice
versa, without additional parts.

 Long Seal Life– The opening and closing path of the

eccentric disk minimizes disk contact with the seal
ring, thereby reducing seal wear, undue friction,
and seating torque requirements. See figure 2.

 Reliable Flange Gasketing Surface– The seal

retainer screws and retention clips are outside the
gasket surface of the seal retainer. Spiral-wound or
flat-sheet gaskets can be installed between the
uninterrupted seal retainer face and the pipeline
flange.

 Integral Shaft-to-Valve Body Bonding– Standard

valve construction includes conductive packing to
provide electrical bonding for hazardous area
applications.

 Powder paint as standard– The Emerson Process

Managementt powder paint finish offers an
excellent corrosion-resistant finish to all steel parts.

 High Temperature Capability– The valve will

operate at elevated temperatures, with the
appropriate trim components.

 Easy Installation– Line-centering clips engage the

line flange bolts to simplify installation and provide
for centering of wafer-style valves in the pipeline.
End connections are compatible with EN and ASME
standards.

 Excellent Shutoff– Both the metal and soft seal

rings have pressure-assisting sealing action that
ensures tight shutoff regardless of pressure drop.

 Shaft Retention– Redundant shaft retention

provides added protection. The packing follower,
anti-blowout ring, and shaft groove interact to hold
the shaft securely in the valve body (see figure 1).

 Travel Indication– Additional travel indication can

be achieved by using the indication line on the
shaft, along with the disk position markings on the
packing follower (see figure 4).
