High-Performance Butterfly Valve

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.

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 construction, 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.

 Excellent Shutoff Integrity–The pressure-assisted

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 t o

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. T hese 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.
