41005 Series
Cage-Guided Globe Valves

Excellent Performance and Reliability

Masoneilan 41005 Series cage-guided control valves from GE
Energy provide highly dependable, field- proven performance
for a variety of critical process control applications in
industries such as power, onshore and offshore oil and gas,
petrochemical, and refining. The valves’ rugged design delivers
excellent performance even in severe conditions.

High Process Yields

The 41005 Series provides excellent throttling control
performance resulting in efficient process output and high
process yields. The balanced trim construction reduces the
resultant forces acting on the valve plug, which decreases the
actuator thrusts required to move and position the plug. Even
at high temperatures, the use of low friction Teflon® packing
further enhances throttling performance. This is made possible
by the extended packing box design in the standard 41005
Series bonnet.

Lower Operating Costs

Dependable control-valve tight shutoff helps minimize the loss
of valuable process fluids and potentially can eliminate the
need for separate isolation valves. In addition, excessive valve­seat leakage can lead to premature trim wear and reduced
performance.

High Reliability

Standard hardened trim materials in the 41005
Series provide excellent wear resistance and long life even
under high-pressure and high-temperature conditions.
Various trim options are available to control and reduce the
potentially damaging effects of noise and cavitation. Overall
valve reliability also is enhanced with minimized application of
soft goods such as gaskets and seals.

Low-Emissions Compliance

Addressing environmental concerns surrounding fugitive
emissions from industrial plants, GE Energy offers low­emissions packing options for all Masoneilan globe valve
designs meeting various global and regional requirements. The
EPA-compliant Masoneilan LE* Packing design also is available
in a fire- safe version.

The 41005 Series is available with a pilot-balanced trim option
for tight shutoff (Class V) at high temperatures, and a soft-seat
design for bubble-tight (Class VI) shutoff in accordance with
ANSI/FCI and IEC specifications.

Customer Benefits

Design Simplicity

Sizing and selection is simplified with the versatile 41005
Series valve design, which provides various trim options
in a common platform to handle a wide range of appli­cations. This also allows users to easily modify, upgrade
or change trim style in the field by simply replacing trim
components to accommodate changes in process condi­tions.

Compact Design

Compared to equivalent valve designs, the 41005 Series
offers ease of handling and installation with a compact,
low weight, and low profile assembly. Valve orifice sizes
are configured for capacity and noise performance, while
body bowl dimensions are streamlined resulting in a
highly efficient valve package.

Ease of Maintenance

Simple top-entry access to the 41005 Series trim
components provides a maintenance- friendly design,
which is further enhanced with the quick change trim
construction. The versatility and reduced number of parts
used in the 41005 Series design can help reduce overall
plant inventory costs. Making maintenance and repairs
even easier, there are no special components, such as
shims, required in the assembly.

Advanced Digital Performance

Greater control resolution and accuracy are available
when the 41005 Series is supplied with smart valve
instrumentation such as the Masoneilan SVI*II AP or the
Masoneilan FVP*. Since both instruments are available
in single- or double-acting configurations and offer
advanced control technology, they provide higher
precision for pneumatically actuated control valves. In
addition, Masoneilan’s ValVue
software provides real-time preventive and predictive
diagnostics data that helps to ensure critical control
valve asset availability and to maximize end user return
on investment.
