Introduction
The Baumann 51000 control valve (figure 1) is optimally designed for demanding low flow control and is a perfect fit
where space is at a premium. This compact package provides the connection integrity of flanged body globe valves,
while being significantly lighter and easier to install.
Scope of Manual
This instruction manual includes installation, maintenance, and parts information for the 51000 control valve and
Baumann 16 actuator.
Do not install, operate, or maintain Baumann 51000 control valves without being fully trained and qualified in valve,
actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is
important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and
warnings. If you have any questions about these instructions, contact your Emerson Process Management sales office
before proceeding.

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
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:
DDo not remove the actuator from the valve while the valve is still pressurized.
DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations.
DDisconnect 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.
DUse 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.
DDepending 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.
DUse lock-out procedures to be sure the above measures stay in effect while you work on the equipment.

DThe 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.
DCheck 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 damage to the seating and sealing surfaces of the valve and result in
damage to the valve and release of process materials.
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.
3. Athree-valvebypasspermitsremovalofthecontrolvalvefromthelinewithoutshuttingdownthesystem.
4. In case of a heat-insulated installation, insulate the valve body only, not the bonnet.
Actuator Removal
Refer to figures 2, 3, 7, and 8.
1. For air to open actuators, lift actuator travel with air to lessen tension on the upper clamp nut (key 10).
Note
For air-to-close, this is NOT required
2. Gently tap the upper clamp nut (key 10). With slight downward pressure on top of the actuator, unscrew the upper
clamp nut (key 10) completely.
3. The Baumann 16 actuator assembly must be unscrewed from the stem adapter (key 26).

Plug and Packing Replacement
Refer to figures 2 and 3.
CAUTION
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.
1. For valves supplied with Baumann 16 actuators, remove the travel indicator disc (key 58). With the hex jam nuts
(key 27) still tight, loosen the stem adapter (key 26) from the stem adapter nut (key 31), and unthread the stem
adapter (key 26) from the plug stem (key 4).
For valves with rated Cv's less than 1.0, unscrew the packing nut (key 11) and gently pull the plug (key 4) out through
the top of the bonnet (key 6).
For valves with rated Cv's greater than or equal to 1.0, follow the VALVE DISASSEMBLY instructions to first remove the
bonnet (key 6) before removing the plug (key 4).
2. Inspect or replace the packing (key 9) and the stem guide (key 8).
3. Inspect the valve plug (key 4) for wear or particle accumulation.
Valve Disassembly
Refer to figures 2 and 3.
Note
The actuator must be removed from the valve body before valve body disassembly.
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.
1. Remove the bonnet hex nuts (key 7) and lift the bonnet (key 6) off the valve body (key 1), which may include the
packing (key 9) and plug assembly (key 4) [For alloy valve bodies, lift the bonnet flange (key 34) off from the bonnet
(key 6) and then lift the bonnet (key 6) off the valve body (key 1)].
2. Remove the bonnet gasket (key 5) and replace.
3. Thecagesubassembly(key3)canberemovedbyunscrewingwith a flat screwdriver, using the outer screw slot, and
lifting out of the valve body (key 1). The cage subassembly should be inspected and cleaned with water or an
approved solvent.
For valves with rated Cv's greater than or equal to 1.0, remove and inspect the plug guide (key 33) for wear. Replace if
necessary. Replacement of the entire assembly will be necessary if excessive leakage or wear has occurred in service.
Note
The seat cage gasket (key 2) must be replaced when the cage subassembly (key 3) has been removed. The seat cage will appear
oblong. This is to prevent loosening of the soft seat.
