Fisherr 8560 Eccentric Disc
Butterfly Control Valve
Fisher 8560 high-performance valves feature a
stainless steel disc with a soft or stainless steel seal
ring. Soft seals provide excellent sealing capabilities in
both directions. The pressure-assisted metal seal ring
provides excellent shutoff against pressure applied in
the recommended flow direction for both liquid and
gas applications.
The NOVEX and Phoenix III metal seals are available for
demanding applications requiring excellent shutoff
capabilities. The splined-shaft valve combines with a
variety of power actuators to form a reliable,
high-performance control valve suitable for throttling
applications requiring extremely low leakage rates.
Unless otherwise noted, all NACE references are to
NACE MR0175-2002.

W8299- 2

Fisher 8560 Valve with 1052 Actuator and FIELDVUEt
DVC6200 Digital Valve Controller

Features


Exceptional Shutoff–Bidirectional soft seal ring
with pressure assisting action (see figure 1) results
in exceptional shutoff per Class VI.



Excellent Flow Control–The eccentrically- mounted
disc design provides an approximate linear flow
characteristic and can be used for throttling or
on/off control applications through 90 degrees of
disc rotation.



Sour Service Capability–Trim and bolting materials
are available for applications involving sour service.
These constructions comply with the
recommendations of NACE MR0175-2002.
Improved Environmental Capabilities–The optional
ENVIRO-SEAL packing system is designed with
improved sealing, guiding, and loading force
transmission. The ENVIRO-SEAL packing system can
control emissions to below the EPA (Environmental

www.Fisher.com

W6361

Fisher 8560 Single-Flange Valve

Protection Agency) limit of 100 ppm (parts per
million) for valves.


Integral Shaft-to-Body Bonding–Standard valve
construction includes conductive packing to
provide electrical bonding for hazardous area
applications.



Low Cost Maintenance–Individual disc/shaft
components can be replaced after disassembly due
to sleeve and taper pin connections (see figure 1).

ENVIRO-SEALt Packing
This optional J PTFE or J graphite packing system
provides improved sealing, guiding, and transmission

(see figure 5). See Bulletin 59.3:041 ENVIRO-SEAL
Packing Systems for Rotary Valves for more
information.

1. The pressure-temperature limits in this bulletin and any applicable standard or code limitation should not be exceeded.
2. For component selection and applicable fire-tested standards and codes, consult your Emerson Process Management sales office (see table 2).
3. UHMWPE stands for ultra high molecular weight polyethylene.
4. Ratio of maximum flow coefficient to minimum usable flow coefficient.
5. Weight of the CL600 NPS 2 valve is the same as the CL150 and CL300 values.

Installation
It is recommended that the valve drive shaft be
mounted in a horizontal position as shown in the
figures on page 1. Operating conditions may require
specific valve/actuator fail action, styles, positions and
flow direction. Valves with NOVEX seal rings require
mounting in the reverse flow direction. Refer to figure
4. Large valve/actuator assemblies may require
additional support because of their combined weight.

Fail Action: For actuators with spring returns, spring
fail action is available for push-down-to-open or
push-down-to-close valve action. The valve action is
field reversible.
For assistance in selecting the valve/actuator
mounting suited to your application, consult your
Emerson Process Management sales office.
Dimensions for wafer-style and single-flanged valves
are shown in figure 6.
