Introduction

Baumann Little Scotty industrial control valves (figure 1) are intended for general utility service in pressure, flow, and

temperature control applications.

Industrial grade control valves exhibit low hysteresis and deadband, good control characteristics, tight shutoff, rugged

construction, high performance packing, and easy maintainability. This translates into reduced maintenance costs,

reduced process variability, and increased process availability.

Scope of Manual

This instruction manual includes installation, maintenance, and parts information for the Baumann 24000 bronze

control valve.

Do not install, operate, or maintain Baumann 24000 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

Instruction Manual D103355X012 24000 Valve May 2012 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.

If air line exceeds 8 m (25 ft) in length, 9.5 mm (3/8 inch) tubing is preferred. Air pressure not to exceed 2.41 barg (35 psig). Disassembly WARNING If there is evidence of process fluid under pressure leaking from the joint, retighten the valve body/joint nuts and return to the Warning at the beginning of the Maintenance section.

24000 Valve May 2012 Instruction Manual D103355X012 Carefully position actuator over stem (key 5), lift plug stem and turn plug stem (key 5) into actuator stem as far as it will go before adjusting bench range. See the following instruction manual (Baumann Actuator Instructions, D103352X012). 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. Figure 2.
