Installation
Key numbers are shown in figure 10, unless otherwise indicated.
WARNING
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed either the valve body rating or the mating pipe flange joint rating. To avoid such injury or damage, provide a relief valve for overpressure protection as required by government or accepted industry codes and good engineering practices.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
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
.
Install the valve with the drive shaft in the horizontal position as shown in figure 1.
CAUTION
To maximize seal life, the valve should be installed so the drive shaft will be in the horizontal orientation while in service. Please contact your Emerson sales office for evaluating vertical drive shaft installations.
1. If the valve is to be stored before installation, protect the flange mating surfaces and keep the valve cavity dry and
free of foreign material.
2. Install a three‐valve bypass around the control valve assembly if continuous operation will be necessary during
inspection and maintenance of the valve.
3. Mounting the Actuator:
a. The valve is normally shipped as part of a control valve assembly, with the actuator mounted on the valve. The
factory makes actuator/valve adjustments before the valve is shipped.

D101957X012
b. If the valve and actuator have been purchased separately or if the actuator has been removed, mount the
actuator according to the Actuator Mounting section of this manual.
4. Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve seating
surfaces.
5. Be sure the mating line flanges are aligned. Provide standard flat sheet flange gaskets (or spiral wound gaskets with
compression‐controlling centering rings) that are compatible with the process fluid.
Refer to figure 2 for required clearance for valve installation and stud length. Lubricate the studs with anti-seize lubricant.
6. Install the valve using studs and nuts to connect the valve flanges to the pipeline flanges. The seal protector ring
(key 3) end of the valve requires longer line flange studs than standard (see figure 2).

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 discharge of static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to the valve.
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 rings. 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 and figure 4).
7. For hazardous applications, attach the optional bonding strap assembly (key 131, figure 4) to the valve drive shaft
(key 6) with the clamp (key 130, figure 4) and connect the other end of the bonding strap assembly to the valve body with the cap screw (key 23).
8. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When an auxiliary manual
actuator is used with a power actuator, install a bypass valve on the power actuator (if one is not supplied) for use during manual operation.
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing might need 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.
If the valve has ENVIRO‐SEAL live‐loaded packing installed, this initial re‐adjustment will probably not be required. Refer to the ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012
) for packing
instructions.
Maintenance
Valve parts are subject to normal wear and must be inspected and/or replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions.
WARNING
The Vee‐ball closes with a cutting motion. To avoid personal injury, keep hands, tools, and other objects away from the ball while stroking the valve.
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized. D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Make 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 lock‐out procedures to be sure that 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.

Packing Maintenance
Key numbers are shown in figure 10, unless otherwise indicated. A detailed view of the packing is also shown in figure
3.
If the valve is equipped with the ENVIRO‐SEAL Packing System, refer to the ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012
Note
For the ENVIRO‐SEAL Packing System, refer to the Parts List section for individual parts (see figure 3). Refer to the ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012) for maintenance instructions.
Stopping Leakage
For PTFE V‐ring packing, leakage around the packing follower and packing flange (keys 17 and 40) can be stopped by tightening the packing follower nuts (key 20).
).
If the packing is relatively new and tight on the drive shaft (key 6), and if tightening the packing follower nuts does not stop leakage, it is possible that the drive shaft is worn or nicked so that a seal cannot be made. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks, scratches, or corrosion on the packing box wall.
If the leakage cannot be stopped by the above steps, the packing must be removed and replaced. Inspect the drive shaft and packing box before installing new packing parts.
Packing Replacement
When replacing the packing, the actuator should not be removed from the valve while the valve is still in the pipeline or between flanges. Valve/actuator adjustments must be made with the valve out of the pipeline.
Disassembly
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve, 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 work on the equipment.
2. Remove line bolting, remove the control valve from the pipeline, and place the actuator/valve assembly on a
protected flat surface with the seal protector ring facing up.
3. Remove the actuator cover. Note the orientation of the actuator with respect to the valve body and the lever
orientation with respect to the valve drive shaft (see figure 8).
WARNING
When the actuator is removed from the valve, the ball/shaft assembly may suddenly rotate, resulting in personal injury. To avoid injury, carefully rotate the ball to the stable position after the actuator is removed.

CAUTION
When removing the actuator from the valve, do not use a hammer or similar tool to drive the lever or actuator off the valve shaft. Driving the lever or actuator off the valve shaft could damage the ball, seal, and valve.
If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. It is okay to tap the wheel puller screw lightly to loosen the lever or actuator, but hitting the screw with excessive force could damage the ball, seal, and valve.
Note
Some actuator designs have a bolt inserted in the lever to spread the clamp on the valve spline shaft. Tightening the bolt expands the splined lever connection allowing the valve shaft to be removed.
4. When removing the lever (do not loosen the actuator turnbuckle adjustment), remove the actuator mounting
screws and nuts (keys 23 and 24), and remove the actuator. (If necessary, refer to the actuator instruction manual for assistance.)
5. If necessary, remove the bonding strap assembly before attempting to remove the packing (see figure 4).
6. Remove the packing flange and nuts and packing follower (keys 20, 40, and 17).
If the valve is equipped with the ENVIRO‐SEAL packing system, refer to the ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012)
for disassembly.
7. Remove the packing parts (key 16 packing set includes additional key numbers) by making a formed wire hook with
a sharp end. Pierce the rings with the sharp end of the hook in order to remove them. Do not scratch the drive shaft or packing box wall; scratching these surfaces could cause leakage. Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing. (Note: Metal packing parts are not provided in the packing set).
Assembly
If the valve is equipped with the ENVIRO‐SEAL packing system, refer to the ENVIRO‐SEAL Packing System Rotary Valves instruction manual (D101643X012) for assembly.
1. Install the new packing parts using the parts sequence shown in figure 3.
2. Insert the packing follower and packing flange (keys 17 and 40) and secure them with the packing follower nuts
(key 20). Tighten the nuts far enough to stop leakage during operating conditions.
Note
If the valve is equipped with a bonding strap assembly (figure 4), re‐install the assembly.
3. Reconnect the actuator and lever in accordance with the orientations that were noted in step 3 of the disassembly
procedures. If necessary, use figure 8 to identify the correct index marks.
4. If necessary, refer to the appropriate actuator instruction manual to complete actuator assembly and adjustment.
5. When the control valve is in operation, check the packing follower for leakage and retighten the packing follower
nuts (key 20) as necessary.
Ball Seal Replacement
Perform this procedure if the control valve is not shutting off properly, or if seal inspection is necessary. Remove the actuator/valve assembly from the pipeline.
