Fisherr POSI-SEALt A31D Double-Flange
High-Performance Butterfly Valve
The Fisher A31D double-flange high-performance
butterfly valve provides outstanding performance
under extreme pressure and temperature conditions.
The A31D valve is available with face-to-face
dimensions conforming to ISO 5752 Butterfly Valve
Short (CL150) or Long (CL300) Series (for other
face-to-face dimension requirements, consult your
Emerson Process Management sales office). A splined
shaft combines with a variety of Fisher
spring-and-diaphragm or pneumatic piston actuators.
A keyed drive shaft combines with a variety of
handlevers, handwheels, or pneumatic double-acting
or spring-return piston actuators. These combinations
make the A31D valve a reliable, high-performance
butterfly valve for both throttling and on-off
applications in the process industries.
TheA31Dvalvecanbesuppliedwithoneofseveral
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 provides excellent shutoff
against the full ASME class pressure range.

Features
Excellent Shutoff Integrity-- The pressure-assisted
seal design provides tight shutoff and permits the
use of smaller actuators in applications requiring full
ASME B16.34 shutoff capabilities.
True Bi-directional Shutoff Performance-- A31D
valve design helps to ensure that the torque
necessary to open and close the valve is the same
regardless of the direction in which the differential
pressure is applied.
Safety-- Shaft-blowout protection is designed into
the A31D valve (figure 2). For NPS 3 through 12
valves, the packing follower and an anti-blowout
follower hold an anti-blowout gland securely around
the valve shaft. Under the anti-blowout gland, a
formed wire ring around the shaft completes the
protection design. For NPS 14 through 24 valves,
the anti-blowout gland fits securely over the valve
shaft which has been turned down to form a
circumferential shoulder that contacts the
anti-blowout gland.

Excellent Emissions 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
Protection Agency) limit of 100 ppm (parts per
million) for valves.
Shaft Versatility-- This valve will meet your actuator
needs with a choice of splined or keyed shaft
connections.

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.
Reliable Flange Gasketing Surface-- Seal retainer
screws are located so there is no interference with
the sealing function of either flat sheet or spiral
woundlineflangegaskets.
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
Recommended or “preferred” installation for the A31D
valve is with the flow into the shaft side of the disk
(retaining ring downstream from the high pressure
side of the valve).
The standard soft seal offers ANSI/FCI 70-2 Class VI,
bidirectional shutoff. The Phoenix III seal should be
installed in the preferred direction to obtain optimal
shutoff performance, and it must be installed in the
preferred direction for fire-tested applications. The
NOVEX seal is uni-directional and should be installed in
the preferred direction.
For assistance in selecting the appropriate
combination of actuator action and open valve
position, contact your Emerson Process Management
sales office.
Standard Seal
Configurations
Standard Soft Seal (PTFE)-- A resilient dynamic seal
with an elastomeric back-up ring for low to
moderate temperature applications.
NOVEX Seal-- The NOVEX stainless steel seal is
available for severe service, Cryogenic, and
high-temperature applications.
Phoenix III Seal-- This three-component,
metal-and-polymeric seal is available for severe
service with low to moderate temperature
applications.

Because of potential erosive and premature seal failure that can occur, throttling PTFE seals at differential pressures greater than 300 psid at disk angles less than
20 degrees open is not recommended.

Temperature limitations do not account for the additional limitations imposed by the backup O-ring used with this seal. To determine the effective temperature
