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:
3
Control-Disk NPS 14-36
April 2011
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.
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.
Instruction Manual
D103545X012
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 disk will occur if any pipe flanges or piping connected to the valve interfere with the disk rotation path. If
the piping flange has a smaller inner diameter than specified for schedule 80 piping, measure carefully to be certain the disk
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 disk (key 2, figure 9) close with a shearing, cutting motion. To avoid personal injury, keep
hands, tools, and other objects away from the disk while stroking the valve.

If the Control-Disk 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 a manual actuator, a constant supply pressure to the pneumatic actuator, or other
steps as necessary.

A Control-Disk valve is normally shipped as part of an assembly with an actuator and other accessories such as a valve
positioner. If the valve and actuator have been purchased separately or if the actuator has been removed for
maintenance, properly mount the actuator and adjust valve/actuator travel before inserting the valve into the line.
CAUTION
Damage to the disk will occur if any pipe flanges or piping connected to the valve interfere with the disk rotation path. Be
certain to align the valve accurately to avoid contact between the disk (key 2) and the flanges.

Adjusting the Actuator Travel
Key number locations are shown in figure 9, unless otherwise noted.
1. Adjust the actuator to bring the disk to the fully closed position at the end of the actuator stroke. To determine the
fully closed disk position, measure the distances between the disk face and the seal retainer face at the top and
bottom of the valve (X1 and X2) as shown in figure 3. Adjust the actuator to rotate the disk slightly until the two
measurements are within 0.8 mm (0.032 inch) of each other. Refer to the appropriate actuator instruction manual
for assistance.
2. 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.

Installing the Valve
The maximum allowable inlet pressures for Control-Disk valves are consistent with the applicable ASME
pressure/temperature ratings except where limited by the material capabilities as shown in table 2 or figure 2.
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 disk during installation, the valve must be in the fully closed position. If the Control-Disk 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.

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 Control-Disk valves depending on the service
conditions of the application.

3. For Wafer‐Style Valves: Properly orient the valve according to the specific application. Place the valve in the line so
the flow properly enters the valve as indicated by the flow tag. Then, install the valve and the gaskets between the
flanges into the cradle formed by the flange bolts.
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.
