The Fisher A11 High-Performance Butterfly Valve
maintains tight shutoff, and can be specified for a wide
range of pressure and temperature conditions,
including cryogenic applications.
TheA11valveisavailableineitherawaferora
single-flange design (single-flange only for CL600, 900,
and 1500). A square or keyed shaft can combine with a
variety of handlevers, handwheels, or pneumatic
piston diaphragm actuators. A splined shaft can
combine with a variety of spring-and- diaphragm or
pneumatic piston actuators. These combinations help
make the A11 valve a reliable, high-performance
butterfly valve for both throttling and on-off
applications in the process industries.

The A11 valve can be supplied with one of several
dynamic seals (figure 1) that can be used in a variety of
demanding applications. With the appropriate seal
selection and materials of c onstruction, the
pressure-assisted seal helps provide excellent shutoff
against the full ASME class pressure range for the A11
valve.
Features
Shaft Versatility– This valve will meet your actuator
needs with a choice of square, keyed, or splined
shaft connections.
seal design provides tight shutoff and permits the
use of smaller, less expensive actuators in
applications requiring full ASME B16.34 shutoff
capabilities.
W9570-1
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.
High-Temperature/Cryogenic Capabilities–
Optional valve constructions allow this valve to
meet both high-temperature and cryogenic
applications (see table 7 for cryogenic and
high-temperature actuator configurations).
Easy Installation–The valve body self-centers on the
line flange bolts as a fast, accurate means of
centering the valve in the pipeline.

Installation
Preferred valve orientation for the A11 valve is reverse
flow direction. Reverse flow direction is into the side of
the valve body opposite the retaining ring or into the
shaft side of the disc.
For erosive and many severe service applications,
valves with bidirectional seals can and should be
installed with the shaft horizontal and in the forward
flow direction to prevent direct impingement of the
process media on the seal, and to minimize the
exposure of the shaft bearings to the process media.
4
The standard soft seal and the Phoenix III seal both
offer bidirectional shutoff. Valves using either metal,
NOVEX, or cryogenic seals are unidirectional and must
be installed in the reverse flow orientation.
For assistance in selecting the appropriate
combination of actuator action and open valve
position, consult your Emerson Process Management
sales office.
