Features and Benefits

GE’s Masoneilan* 77000 series high-pressure labyrinth trim control
valve from GE delivers exceptionally stable control and durable
service life while saving replacement and maintenance costs. It
provides high-pressure, compressible fluid control without the
erosion, vibration, and high noise associated with conventional
control valves.

Ideal for service in multi-phase flow applications, the Masoneilan*
77000 series valve’s advanced energy management trim design
stands up to the damaging and abrasive conditions caused by
entrained liquids/solids or liquids with entrained solids. It features
an expanding area flow passage, and its multiple step plug and
seat ring design creates a beneficial shearing action across each
stage to manage the gradual pressure reduction.

Energy Management Trim

This valve applies the principle of energy management
technology to gradually reduce pressure through the creation of
flow path friction. This simulates the gradual pressure loss that
occurs over long pipelines. By passing the fluid through a number
of restrictions, referred to as pressure reduction stages, the
Masoneilan* 77000 series valve’s tortuous flow pattern dissipates
energy through high head loss rather than through shock waves.

Additionally, the flow area of the trim is gradually increased at
the latter stages of the design to compensate for the volumetric
expansion of the gas caused by the reduction in pressure. This
ensures nearly constant fluid velocity throughout the complete
throttling process and eliminates the damaging effects of high
energy spikes within the trim.

The reduced velocity minimizes the impact of erosion caused
by entrained solids or liquids resulting from a process fluid
phase change. Plus, the acoustical performance of the valve
is optimized through alignment of the pressure drop ratio with
the trim expansion factor. In some cases, downstream Lo-dB
cartridges or custom design trim areas are integrated into the
control valve design for extremely high-pressure drop ratios.

The unique axial flow construction of the Masoneilan* 77000
series valve is optimal for flashing or de-gassing applications.
The axial flow path within the angle body design directs the two­phase fluid away from critical surfaces and the downstream pipe
wall.

Smooth, Stable Control

The high range (50:1) of this multi-stage valve allows wide
variations in controlled flow. Intermediate pressure flows through
internal plug porting for exceptional control stability. This creates a
balance force within the plug to minimize unbalanced force acting
on the trim.

What’s more, this uniquely balanced trim design has no secondary
balancing seal and only a single point for seat contact.

A toggle design for the actuation system provides high force
amplification through mechanical leverage resulting in stable
control during the throttling phase.

Adding GE’s Masoneilan* SVI* II Advanced Performance positioner
provides further process control, delivering high-precision valve
control and immediate response to the smallest step change in
signal.

Cavitation Elimination

The valve’s multi-stage trim design reduces the pressure drop in
smaller increments without allowing the local pressure at each
stage to drop below the fluid vapor pressure, thus preventing
cavitation. The actively controlled stages of this axial flow
design valve throttle in unison to avoid the adverse effects of an
exaggerated reduction at any single stage.

Dirt Tolerance

Wide flow paths in the trim allow for passage of large particles
entrained within the flow stream that would otherwise cause
damage or loss of capacity. This ensures continuous and efficient
operation by eliminating concerns of potential clogging due to
debris in the flow stream. GE’s Masoneilan* 77000 series valve
offers a proven design for many high-pressure, dirty service
applications, including wellhead choke valves.

Reliable Tight Shutoff

The standard seat design’s leakage rating meets IEC534-4 and
ANSI/FCI 70.2 Class V shutoff requirements. The valve can also be
supplied with block valve tight shutoff to comply with MSS-SP-61
specifications.

Features and Benefits

Ease of Maintenance

GE’s Masoneilan* 77000 series valve comes in two design styles
for easy trim access in the field; a bottom-loaded flanged end
connection design and a top-loaded butt-weld end design provide
field maintenance flexibility.

In addition, short valve travel reduces packing wear and
significantly extends packing life, particularly in high-pressure/
high-temperature service.

Enhanced service life is achieved through the trim’s heavy guiding
coupled with the use of hardened materials on the seat and
guiding surfaces.

NACE and PED Compliance

GE’s Masoneilan 77000 series valve is available for sour service
applications using the design and construction methods defined

in NACE standard MR0103. Product configurations for applications
requiring MR0175 – 2003 or ISO 15156 compliance are also
available. In addition, the valve is designed for compliance with
Pressure Equipment Directives (PED) requirements.

Noise Prediction

Valve noise calculations can be performed using GE’s Masoneilan*
sizing and selection program based on the latest IEC equations.
Since noise intensity of a free gas jet varies to the eighth power of
the velocity, a 4:1 reduction in fluid through the expanding area can
reduce the expected noise level approximately 255 times (equivalent
to 24 dB). When predicting the overall noise level produced by the
control valve system, calculations of the noise levels at all stages of
the trim and at the outlet area are all considered.

77000 Series High Pressure Labyrinth Trim Control Valves | 5

Expanding Area Trim Design

The circumference of each pressure reduction stage within
the Masoneilan* 77000 series trim is designed to gradually
increase as flow moves towards the downstream section. This
expansion compensates for the change in gas density with the
pressure and ensures a nearly constant fluid velocity throughout
the complete throttling process, providing the valve with two
advantages:

1. Reduction in noise produced by the fluid velocity

2. Considerable decrease in erosion of the plug and seat liner
caused by particulate in the flow stream or fluid flashing

77000 Series High-Pressure Labyrinth Trim Control Valve

For many applications that experience flashing service
conditions, such as supercritical power plant start-up valves
or hot high-pressure separator letdown in refineries, the
Masoneilan* 77000 series valve provides a low-velocity outlet
area to minimize any effect of the phase transformation process.
Similarly for applications with entrained solids, such as gas
wellhead choke applications, the valve reduces the velocity of
the moving particulate to minimize wear and erosive damage to
the trim and outlet flow area.

Many designs include a larger outlet compared to the inlet size
to retain the low velocity as the fluid exits the valve into the
downstream piping. This arrangement eliminates the need for
additional piping modifications, such as downstream reducers.
