Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
Note
When installing a valve after it has been in long‐term storage, cycle the valve at least ten times to re‐energize the dynamic seal.
Please contact your Emerson sales office or Local Business Partner if you have any questions about preparing a valve for storage or
if you are planning to put into service a valve that has been stored for some time.

Adjusting the Travel Stops
CAUTION
When using manual or power actuators, adjust the actuator travel stops so the disk stop in the valve body does not absorb
the output of the actuator.
For actuators without travel stops, the actuator must be properly mounted to prevent it from driving the valve disk against
the valve disk travel stop.
Failure to limit actuator travel as described in this section can result in damage to the valve shafts or other valve parts
Note
An ”S” is visible on both the valve shaft and valve body. When the valve disk is closed, the ”S” on the shaft aligns with the ”S” on
the valve body.
1. Locate the actuator travel stop that establishes the closed position of the valve disk. When adjusting the travel stop
make sure that the disk is from 0 to 0.76 mm (0 to 0.030 inch ) away from the internal stop in the valve body. This
adjustment is necessary to be certain that the actuator output torque is fully absorbed by the actuator travel stop
rather than the stop in the valve body.
For actuators without travel stops, the actuator must be properly mounted to prevent it from driving the valve disk
against the valve disk travel stop.
2. To mount an actuator without travel stops, first, if necessary, remove the actuator from the valve. Then, position
the valve disk from 0 to 0.76 mm (0 to 0.030 inch) away from the internal stop in the valve body.
3. Now, travel the actuator to the maximum position. Keep the actuator in the maximum travel position. Return the
actuator to the valve, taking care not to disturb the position of the valve disk.
4. Mount the actuator on the valve using proper bolts with locking washers to achieve a secure fit.
5. Before installing the valve/actuator assembly in the process line, cycle the valve several times to be sure the valve
disk returns to the proper position.
Preparing for Installation
WARNING
If the A11 valve is equipped with a fail‐open actuator, remove the actuator before installing the valve/actuator assembly or
cycle the valve into the fully closed position. Then, to avoid possible personal injury or property damage, take appropriate
steps to ensure that the actuator does not cause the valve to open during installation.
1. If the valve and actuator have been purchased separately or if the actuator has been removed for storage, travel
stop adjustment, or maintenance, mount the actuator before inserting the valve/actuator assembly into the line.
Refer to the actuator instruction manual for mounting and adjustment procedures.
CAUTION
To avoid product damage, inspect the valve before installation for any damage or any foreign material that may have
collected in the valve body. Also remove any pipe scale, welding slag, or other foreign material from the pipeline.

2. Remove the protective end covers from the valve and inspect the valve body to be certain that it is free of foreign
material. Also, be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag
that could damage the valve seating surfaces.
WARNING
The A11 valve is designed for use with the appropriate piping schedule for the ASME class. However, before putting the
valve into operation, measure carefully to ensure disk rotation without interference from piping or flanges. Be certain to
center the valve accurately to prevent interference of the disk with the flanges.
The edges of a rotating disk have a shearing effect that may result in personal injury. To help prevent such injuries, stay
clear of the disk edges when rotating the disk.
Damage to the disk will occur if any pipe flanges or piping connected to the valve interfere with the disk rotation path.
Compare the disk chordal swing diameter from the dimensional tables in Bulletin 51.6:A11 CL900-2500 A11 High
Performance Butterfly Valve (D104222X012) to the ID of the pipe to be certain the disk rotates without interference before
putting the valve into operation. Consult with your Emerson sales office or Local Business Partner for any constructions not
listed in the bulletin.
3. Select the appropriate gaskets for the application. flexible graphite, spiral wound, or other gasket types, made to
ASME B16.5 group or user's standard, can be used on A11 valves depending on the service conditions of the
application. Note: spiral wound gaskets, when properly centered, will cover more than 60 percent of the gasket
area at the retaining ring screws.
For metal‐seated and cryogenic valve gasket recommendations, please contact your Emerson sales office.
4. Refer to the appropriate table for the quantity and size of flange bolts required (table 3) and proceed with the
following instructions.
Valve Orientation
A11 valve bodies are designed for installation with the shaft in any orientation around the pipeline: horizontal, vertical,
or at an angle. However, when installing an A11 valve, please follow these recommendations.

D In certain services (process fluids with high concentrations of entrained solids, abrasive slurries, or polymerizing
media), valve performance will be enhanced by installing the valve with the shaft horizontal to the pipeline.
D Valves supplied for unidirectional shutoff should be installed with the high pressure at the back (shaft side) of the
disk. A flow tag with an arrow is provided for proper installation.
The High Performance Butterfly Valve is designed to allow flow in either direction when in the open position. When in
the closed position, high pressure should be applied to a specific side of the disk to provide best performance and
optimal service life.
D Valves supplied for bidirectional shutoff, such as soft seal constuctions, under normal operating conditions can (at
different times) experience pressure in both directions; the highest of the two pressures should be exerted on the
preferred side of the disk. If the two pressures are equal, then the one lasting the longest period of time should be
applied to the preferred side. A flow tag with an arrow is provided for proper installation.
If you have questions about proper valve orientation in a specific application, contact your Emerson sales office or
Local Business Partner.
Installing the Valve
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given in this manual, the limits on the appropriate nameplates,
or the matching pipe flange rating. Use pressure‐relieving devices as required by government or accepted industry codes
and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.

CAUTION
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
materials with process media rests solely with the purchaser and end‐user.
Because some valve/body trim material combinations are limited in their pressure drop and temperature ranges, do not
apply any other conditions to the valve without first contacting your Emerson sales office or Local Business Partner.

Packing Adjustment and Shaft Bonding
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing
might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any
additional measures that must be taken to protect against process media.
1. For PTFE or graphite packing: Tighten standard packing follower nuts only enough to prevent shaft leakage.
Excessive tightening of packing will accelerate wear and could produce higher rotating friction loads on the valve
shaft. If necessary, refer to the Packing Maintenance section.
2. For ENVIRO‐SEAL Packing Systems: These packing systems will not require this initial re‐adjustment. Refer to the
separate ENVIRO‐SEAL Packing System for Rotary Valves Instruction Manual (D101643X012).
3. For hazardous atmosphere or oxygen service valves, read the following Warning, and provide the bonding strap
assembly mentioned below if the valve is used in an explosive atmosphere.
WARNING
The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could
result, if the process fluid or the atmosphere around the valve is flammable, from an explosion caused by a disk's charge of
static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to
the valve body.
Note
The packing is composed of all conductive packing rings (graphite ribbon packing) or partially conductive packing rings
(carbon‐filled PTFE female adaptor with PTFE V‐ring packing or graphite‐composition packing ring with PTFE/composition
packing) to electrically bond the shaft to the valve for hazardous area service. For oxygen service applications, and hazardous area
service where the standard packing doesn't provide sufficient shaft‐to‐valve body bonding, provide alternate shaft‐to‐valve body
bonding according to the following step.
4. Attach the bonding strap assembly (key 131, figure 4) to the shaft with the clamp (key 130, figure 4).
5. Connect the other end of the bonding strap assembly to the valve flange cap screws.
6. For more information, refer to the Packing Maintenance section below.

Maintenance
Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection
and replacement depends upon the severity of service conditions.
WARNING
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Vent the power actuator loading pressure.
D Use lockout procedures to be sure the above measures stay in effect while you work on the equipment.
D Always wear protective gloves, clothing and eyewear when performing any maintenance operations to avoid personal
injury.
D The valve packing area may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
CAUTION
When using an actuator, the actuator travel stop (or actuator, for actuators without adjustable stops) must be adjusted so
the disk stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel can result in
damage to the valve, shaft(s), or other valve components.
