Figure 1 - 72000 Series  

Energy Management Control Valve

Careful attention must be paid to the serial plate prior 

to pressurizing of the 72000 Series valve. Inlet and 

outlet connections may be independently designed for 

the conditions at their point of operation, thus ASME 

pressure class ratings may differ at each connection.

If major system or piping modifications (or repairs) 

are per-formed, thorough flushing and blowdown of 

the system will be required prior to reinstalling the 

trim. Sacrificial flushing trim should be installed in 

this valve to protect the integrity of the flow passages. 

Failure to follow this warning will violate the valve 

warranty agreement and could result in control 

instability, excessive noise levels, and valve leakage.

Introduction

Scope

The  following  instructions  are  designed  to  guide  the  user 

through the installation and maintenance of the 72000 Series 

Energy Management Control Valves.

The 72000 Series product is part of Masoneilan’s Engineered 

Product portfolio, and is custom designed to fit our customers’ 

most difficult applications. For this reason, sections of this 

instruction manual may be replaced with specific drawings and 

descriptions that apply only to the valves that are specified for 

use on a given project. For further detailed information on your 

specific 72000 Series valve design, please contact your local 

Baker Hughes Sales office.

Serial Plate

The serial plate is usually fixed to the side of the actuator yoke. 

It indicates information about the valve including size and type, 

pressure class rating, body/bonnet material, and serial number. 

After Sales Service

Baker Hughes offers After Sales Service comprised of highly 

qualified technicians to support the installation, operation, 

maintenance and repair of its equipment. For support contact 

your local Sales representative.

Isolation Bypass Valve

To allow for in-line inspection, maintenance and removal of the 

valve without service interruption, provide a manually operated 

shutoff valve on each side of the control valve and a manually 

operated throttling valve in the bypass line.

Spare Parts

Only  Masoneilan  replacement  parts  should  be  used  when 

carrying  out  maintenance  operations.  Obtain  replacement 

parts through local Sales representatives or Masoneilan Parts 

Department.

When  ordering  spare  parts,  the  MODEL  AND  SERIAL 

NUMBERS indicated on the manufacturer’s serial plate MUST 

BE GIVEN. The serial plate is on the side of the actuator yoke.

Actuator and Accessories

Actuators and other valve accessories have their own instruction 

manuals that provide information and details on the assembly 

and installation. Refer to the appropriate instruction manual for 

each unique actuator and accessory.

Unpacking

Care must be exercised when unpacking the valve to prevent 

damage to the accessories and component parts. Contact the 

local Baker Hughes Sales Office or Service Center with any 

issues or problems. Be sure to note the valve model number 

and serial number in all correspondence.

Installation

The 72000 Series Control Valves are designed to handle large 

capacity flow rates. Thus, the overall size and weight of these 

valves  are  larger  than  typical  control  valves.  Proper  piping 

supports and hangers must be used to support  the weight of 

the valve, and the removal of the large trim components during 

periodic maintenance.

Piping Cleanliness 

Before installing the valve in the line, clean piping and valve 

of all foreign material such as welding chips, scale, oil, grease 

or dirt. Gasket mating surfaces must be thoroughly cleaned to 

ensure  leak-free  joints.  Sacrificial  start-up  fixtures  are  highly 

recommended for purchase from Baker Hughes to protect the 

operational trim during the installation and line flushing phases.
