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 Process Management 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 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 for either mixing or

diverting service (see table 1).

3. Athree-valvebypassmustbeusedtopermitremovalofthecontrolvalvefromthelinewithoutshuttingdownthe

system.

4. In case of a heat-insulated installation, insulate the valve body only, not the bonnet.

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

D 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.

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.

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 following

instruction manual (Baumann Actuator Instructions, D103352X012).
