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.
