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 construction, 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 t he 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.
