WARNING
Always wear protective gloves, clothing and eyewear when performing any installation operations to avoid personal injury.
Personal injury or property damage caused by sudden release of pressure or bursting of pressure retaining parts may result
if service conditions exceed those for which the product was intended. To avoid injury or damage, provide a relief valve for
over pressure protection 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
This valve is intended for a specific range of pressures, temperatures and other application specifications. Applying
different pressures and temperatures to the valve could result in parts damage, malfunction of the control valve or loss of
control of the process. Do not expose this product to service conditions or variables other than those for which the product
was intended. If you are not sure what these conditions are you should contact your Emerson Process Management sales
office for more complete specifications. Provide the product serial numbers (shown on the nameplate) and all other
pertinent information.
WARNING
If you move or work on an actuator installed on a valve with loading pressure applied, keep your hands and tools away from
the stem travel path to avoid personal injury. Be especially careful when removing the stem connector to release all loading
on the actuator stem whether it be from air pressure on the diaphragm or compression in the actuator springs.
Likewise take similar care when adjusting or removing any optional travel stop. Refer to the relevant actuator Maintenance
Instructions.
If hoisting the valve, take care to prevent people from being injured in case the hoist or rigging slips. Be sure to use
adequate sized hoists and chains or slings to handle the valve.

WARNING
Personal injury could result from packing leakage. Valve packing is tightened before shipment; however, the packing might
require some readjustment to meet specific service conditions.
Maintenance
WARNING
Avoid personal injury and property damage from sudden release of process pressure or bursting of parts. Before performing
any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when 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 Depending on the actuator construction, it will be necessary to manage the pneumatic actuator spring
pre-compression. It is essential to refer to the relevant actuator instructions in this manual to perform safe removal of
the actuator from the valve.
D Use lock‐out procedures to be sure the above measures stay in effect while you work on the equipment.
D The valve packing box 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, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Note
Whenever a gasket seal is disturbed by removing or shifting gasketed parts, install a new gasket during reassembly. This provides a
good gasket seal because the used gasket may not seal properly.
WARNING
Avoid personal injury or property damage by thoroughly cleaning the line of all dirt, welding chips, scale, oil or grease, and
other foreign material. Failure to do so could result in parts damage, malfunction of the control valve or loss of control of
the process.
Installation
1. Before installing the valve in the pipeline, thoroughly clean the line of all dirt, welding chips, scale, oil or grease, and
other foreign material.

2. Install the valve so the controlled fluid will flow through the valve body in the direction indicated by the arrow cast
on the valve body.
3. A three-valve bypass must be used to permit removal of the control valve from the line without shutting down the
system.
4. In case of a heat-insulated installation, insulate the valve body only, not the bonnet.
Instruction Manual
D103361X012
WARNING
To avoid personal injury or property damage, do not attempt to do any work on a valve while the system is in operation. The
valve must be isolated 100% from the active system and the isolated line voided of pressure and/or hazardous fluids.
Air Piping
1. For an air-to-extend actuator (air-to-close action), connect the actuating air pressure line to the 1/4 NPT opening in
the upper diaphragm case. For an air-to-retract actuator (air-to-open action) connect the actuating air pressure line
to the 1/4 NPT in the lower diaphragm case.
2. Use 6.4 mm (1/4 inch) O.D. tubing or equivalent for all air lines. If air line exceeds 8 m (25 ft) in length, 9.5 mm (3/8
inch) tubing is preferred. Air lines must not leak. Air pressure not to exceed 2.5 bar (35 psig).
Disassembly
WARNING
If there is evidence of process fluid under pressure leaking from the joint, retighten the valve body/joint nuts. Return to the
Warning at the beginning of the Maintenance section to ensure proper steps have been taken to isolate the valve and
relieve process pressure.
CAUTION
D When assembling or disassembling the valve, do not turn the valve stem while the plug is touching the valve seat. This
will damage the valve's seating surfaces.
D When adjusting the valve stem, do not grip the stem directly with pliers or a wrench. This will damage the surface of the
stem, and cause damage to the packing in the valve. Instead, counter-tighten the two locknuts (key 27) on the stem
(key 5). This will allow you to turn the stem by turning the locknuts (key 27) with a wrench.
D When placing the valve in a vise, do not clamp the rounded sides of the valve. This will distort the shape of the casting,
and will ruin the valve.
Actuator Removal
Access to the internal components of the valve body can be accomplished with the actuator removed. For actuator
maintenance see the following instruction manual (Baumann Actuator Instructions, D103352X012).
Air-to-Close Actuators
1. Disconnect the air supply to the actuator and remove the air tubing.

Air-to-Open Actuators
1. Using flexible tubing, apply sufficient air pressure to the actuator to lift the plug off the seat.
2. Loosen the drive nut (key 9) and then remove the plug and stem (keys 4 and 5) assembly by holding the actuator
stem still while unthreading the plug and stem assembly counterclockwise.
3. Remove the stem locknuts (key 27), travel indicator (key 58), and yoke drive nut (key 9).
4. Remove the actuator from the valve.
5. Disconnect the air supply to the actuator and remove the air tubing.
Valve Body Disassembly
1. After removing the actuator, unscrew the bonnet (key 8), and plug and stem (keys 4 and 5) from valve body (key 1).
A new body gasket (key 49) should be installed each time the valve is disassembled.
2. Loosen the packing spring load by removing the packing follower (key 10).
Remove the plug and stem assembly by pulling it out through the bottom of the bonnet (key 8) while rotating the
stem (key 5). This will help prevent damage to the packing components.
Note
Handle the parts carefully to avoid damaging the seating and guiding surfaces. Wipe the parts with a clean soft cloth and examine
for signs of wear or damage.
3. To remove the seat ring (key 2), fabricate a special wrench to engage the lugs on the ring. Clean the seat ring
thoroughly and examine for signs of wear or damage.
4. Low Flow Trims:
a. For Baumann 151 trim (figure 6) unscrew the seat subassembly (key 51) with a 5/8 inch socket wrench. When
reassembling, hand tighten the subassembly (key 51) and then rotate 1/8 of a turn with the 5/8 inch socket to
lock in place.
Note
If changing to Baumann 151 trim, for correct flow characteristics, be sure the valve is reversed in the pipeline so that flow direction
is flow-to-close.
b. For Baumann 177 trim (figure 7) unscrew the retainer nut (key 24) using a 3/4 inch socket wrench. Remove the
gland (key 23) and insert (key 25). Replace the insert (key 25), making sure that the tapered portion faces up. If
replacement of the housing (key 26) is required, use a 5/8 inch socket wrench.
Lapping the Valve Seat
If valve seat leakage becomes excessive, it may be necessary to lap the valve seat.
5
Page 6
24000SB Valve
March 2011
Lapping is the process of mating the valve plug to the seat ring, with an abrasive to produce a close fit. When valve
seat leakage becomes excessive, lapping becomes necessary. The plug and seat ring seating surfaces should be free of
large scratches or dents and the contact surface of the seats should be as narrow as possible.
1. Use a good quality lapping compound with a mixture that contains 280 to 600 grit. Apply at several spots around
the plug seating surface. Replace the plug and stem carefully in the bonnet.
2. Install the bonnet (key 8) into the valve body, without gasket and hand tighten. The bonnet will serve as a guide
during the lapping operation.
3. Lap the valve by applying a slight pressure on the stem and rotate the stem in short oscillating strokes
approximately 8 to 10 times or until you see an even and complete lap line. The plug should be intermittently lifted
and turned 90 degrees while lapping to keep the plug and seat ring concentric.
4. Clean the valve seat and plug (key 4) thoroughly when lapping is complete, removing all traces of lapping
compound.

Replacing Packing
Refer to figure 3 and the standard and optional packing constructions (figure 8) to determine the packing that has
been preinstalled in your valve.
1. Disassemble the valve as directed earlier. Remove the locknuts (key 27) and indicator disk (key 58), and turn the
plug stem (key 5) out through the packing box. Remove the packing follower (key 10). Push out the old packing
(key 14) by working from the underside of the bonnet (key 8).
2. Standard Spring Loaded PTFE V-Ring Packing (figure 3): Carefully insert each piece in exact order shown in figure 8.
Tighten the packing follower (key 10) until it shoulders on the bonnet (key 8). This will compress the packing spring
(key 6) to enable constant stem sealing throughout packing life.
3. Molded Graphite Ribbon Packing (figure 8): Carefully insert each piece in exact order shown in figure 8. Hand
tighten the packing follower (key 10). Use a wrench to increase tightness by turning the follower an additional 60
degrees.
4. ENVIRO-SEALt Packing (figure 8): Carefully insert each piece in exact order as shown in figure 8. Tighten the
packing follower (key 10) until it shoulders on the bonnet, then back off 1/4 turn. This will compress the Belleville
spring (key 17) to ensure constant stem sealing is seated properly throughout the packing life.
Actuator and Valve Body Reassembly
1. Insert a new valve body gasket (key 49) and install the bonnet assembly (key 8).
2. Place the actuator yoke over the stem (key 5). While tilting the actuator back, drop the yoke drive nut (key 9) over
the stem (key 5). Run the locknuts (key 27), and the travel indicator (key 58), down as far as possible and counter
tighten the locknuts (key 27) to lock.
Carefully position the actuator over the stem (key 5), lift the plug stem, and turn the plug stem (key 5) into the
actuator stem as far as it will go before adjusting the bench range. See the following instruction manual (Baumann
Actuator Instructions, D103352X012) for reassembly and bench range adjustment.
CAUTION
When assembling or disassembling the valve, do not turn the valve stem while the plug is in contact with the valve seat.
This can damage the seating surface very quickly.
WARNING
To avoid personal injury or equipment damage due to possible sudden shifting or falling of the valve assembly, do not lift
the valve assembly by the handwheel.
