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:

Instruction Manual
D103545X012
Control-Disk NPS 14-36
April 2011
4
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.
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.

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.

CAUTION
For non‐ENVIRO‐SEAL packing: Tighten the packing follower nuts only enough to prevent shaft leakage. Excessive
tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem.
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
stem. If necessary, refer to the Packing Maintenance section.
2. The ENVIRO‐SEAL Packing Systems will not require this initial re‐adjustment. Refer to the separate instruction
manual ENVIRO‐SEAL Packing System for Rotary Valves, D101643X012, for repair and adjustment procedures.
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 shaft is not necessarily grounded when installed in a pipeline unless the shaft is electrically bonded to the valve.
To avoid personal injury or property damage resulting from the effects of a static electricity discharge from valve
components in a hazardous atmosphere or where the process fluid is combustible, electrically bond the drive shaft (key 3)
to the valve according to the following step.
Note
Standard PTFE packing is composed of a partially conductive carbon‐filled PTFE female adaptor with PTFE V‐ring packing. Standard
graphite packing is composed of all conductive graphite ribbon packing. Alternate shaft‐to‐valve body bonding is available for
hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve (see the following step).
For oxygen service applications, provide alternate shaft‐to‐valve body bonding according to the following step.
4. Attach the bonding strap assembly (key 131, figure 6) to the shaft with the clamp (key 130, figure 6).
