Introduction
The Baumann 24003 3-way control valve (figure 1) is ideally suited for control of flow and temperature where mixing or diverting service is required.
Scope of Manual
This instruction manual includes installation, maintenance, and parts information for the Baumann 24003 3-way control valve.
Do not install, operate, or maintain Baumann 24003 3-way 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 sales office
before proceeding.

Instruction Manual
D103357X012
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 sales office 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 for either mixing or
diverting service (see table 1).
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
D103357X012
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 Port L), 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 Port L) 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).
CAUTION
When assembling or disassembling the valve, do not turn the valve stem while the plug is touching the valve seat. This can damage the valve's seating surface very quickly.
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.
Disassembly
WARNING
When placing the valve in a vise, clamp the flat end faces of the valve. Do not try to clamp the rounded sides of the valve. This will distort the shape of the casting, and damage the valve internals.
1. Mount the valve in a vise.
2. Remove the actuator, stem locknuts (key 27), travel indicator (key 58), and yoke drive nut (key 8). See the Baumann
Pneumatic Actuators Instruction Manual (D103352X012
3. Unscrew the bonnet (key 3) by turning in a counterclockwise direction from the valve body (key 1). Lift the bonnet
up and off the plug and stem assembly (key 4).
4. Unscrew the lower seat ring retainer (key 5) from the valve body (key 1) and remove the plug and stem assembly
(key 4) (see figure 2). Wipe the parts with a clean soft cloth and examine for signs of wear.
).
Lapping the Valve Seat
If valve seat leakage becomes excessive, it may be necessary to lap the valve seat.
