Installation
The valve is normally shipped as part of a control
valve assembly, with the power actuator mounted on
the valve. If the valve or actuator has been
purchased separately, or if the actuator has been
removed for maintenance, mount the actuator on the
valve, and adjust actuator travel before installing the
valve into the line. This is necessary due to the
measurements that must be made during the
actuator calibration adjustment process. Refer to the
Actuator Mounting section of this manual and to the
separate actuator instruction manual for mounting
and adjusting instructions before proceeding.

WARNING
To avoid personal injury or property
damage resulting from the sudden
release of pressure:
D Always wear protective gloves,
clothing, and eyewear when
performing any maintenance
operation.
D Do not install the valve assembly
where service conditions could exceed
the limits given in this manual or on
the nameplates.
Instruction Manual
Form 5288
November 2007
8532 Valve
D Use pressure-relieving devices as
required by government or accepted
industry codes and good engineering
practices to protect from
over-pressurizing the system.
D Check with your process or safety
engineer for any other hazards that
may be present from exposure to
process media.
D 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. Since some 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 Process
Management sales office.
1. Isolate the control valve from the line pressure,
release pressure from both sides of the valve body,
and drain the process media from both sides of the
valve. If using a power actuator, shut off all pressure
lines to the power actuator, release pressure from
the actuator, and disconnect the pressure lines from
the actuator. Use lock-out procedures to be sure that
the above measures stay in effect while you are
working on the equipment.
See the WARNING at the beginning of the
Maintenance section for more information before
removing the valve from the pipeline.
2. Install a three-valve bypass around the control
valve assembly if continuous operation is necessary
during inspection and maintenance of the valve.
3. Inspect the valve to be certain that it is free of
foreign material.
4. Be certain that adjacent pipelines are free of any
foreign material, such as pipe scale or welding slag,
that could damage the valve sealing surfaces.
CAUTION
Damage to the disc will occur if any
pipe flanges or piping connected to
the valve interfere with the disc
rotation path. If the piping flange has a
smaller inner diameter than specified
for schedule 80 piping, measure
carefully to be certain the disc rotates
without interference before placing the
valve into operation. Minimum inside
diameters for flanges or pipe mating
with valves are shown in tables 3
and 4.
Valve Orientation
The valve can be installed in any orientation,
however it is recommended that the valve drive shaft
be horizontal and the actuator vertical as shown in
figure 4.
Install the valve with the high-pressure shutoff side
in the direction noted by the flow arrow for proper
installation, and see figure 4 for more information.
Before Installing the Valve
WARNING
The edges of a rotating valve disc
(key 2, figure 9) close with a shearing,
cutting motion. To avoid personal
injury, keep hands, tools, and other
objects away from the disc while
stroking the valve.
If the Type 8532 valve is equipped with
a fail-open actuator, cycle the valve
into the fully closed position. Ensure
the valve cannot open during
installation by using travel stops, a
manual actuator, a constant supply
pressure to the pneumatic actuator, or
other steps as necessary.

CAUTION
When using an actuator, the actuator
travel stop (or actuator travel, for
actuators without adjustable stops)
must be adjusted so the disc stop in
the valve does not absorb the output
of the actuator. Failure to limit the
actuator travel as described in the
Adjusting the Actuator Travel Stops or
Travel steps can result in damage to
the valve, shaft(s), or other valve
components.

Adjusting the Actuator Travel Stops or
Travel
Key number locations are shown in figure 9, unless
otherwise noted.
1. Refer to the actuator instruction manual to locate
the actuator travel stop that controls the closed
position of the valve disc (key 2). When adjusting the
travel stop or travel, make sure that the disc is from
0 to 0.76 mm (0 to 0.030 inch) away from the
internal stop in the valve body (see figure 5). This
adjustment is necessary to be certain that the
actuator output torque is fully absorbed by the
actuator travel stop or by the actuator. The internal
travel stop in the valve body should not absorb any
of the actuator torque.
2. Before installing the valve/actuator assembly in
the process line, cycle the valve several times to be
sure the valve disc returns to the proper position.
Installing the Valve
The maximum allowable inlet pressures for Type
8532 valves are consistent with the applicable
ASME pressure/temperature ratings except where
limited by the material capabilities as shown in
table 2 or figure 3.
Refer to table 5 for the quantity and size of line
bolting required to install the valve in the pipeline.
CAUTION
To avoid damage to the valve disc
during installation, the valve must be
in the fully closed position. If the Type
8532 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, take appropriate steps
to be sure that the actuator does not
cause the valve to open during
installation.

Figure 4. Installation of Wafer-Style Valves
1. See figure 4 for recommended valve orientation.
D For Wafer-Style Valves: Install the lower
flange bolts first to form a cradle for the valve (see
figure 5). See table 5 for flange bolt specifications.
D For Single-Flange Valves: Position the valve
between the flanges. Be sure to leave enough room
for the flange gaskets. Install the lower flange bolts.
2. For all Valves: Select the appropriate gaskets for
the application. Flat sheet, spiral wound, or other
gasket types, made to the ASME B16.5 standard or
user’s standard, can be used on Type 8532 valves
depending on the service conditions of the
application.
4. Install the remaining flange bolts.
D For Wafer-Style Valves: Make sure the
gaskets are centered on the gasket sealing surfaces
of the flange and body.
5. For all Valves: Tighten the flange bolts in an
alternating criss-cross fashion to a torque value of
one-fourth of the final bolting torque. Repeat this
procedure several times, increasing the torque value
each time by a fourth of the final desired torque.
After applying the final torque value, tighten each
flange bolt again to allow for gasket compression.
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 other
hazards that may be present from
exposure to process media.
