Reliability in Performance

Reliable, Long Term Performance

The leading cause of poor control valve performance and
premature failure in high-pressure, liquid-letdown service
is cavitation. Some liquid applications cavitate so severely
that the valve can experience diminished performance or
even mechanical failure within hours of commissioning. The
multistage design of the LincolnLog valve reduces cavitation
by directing the fluid through a series of three-dimensional,
high-impedance pressure-reduction areas, or stages. This
highly tortuous flow path helps prevent cavitation by managing
the pressure reduction and fluid velocity through every stage,
promoting repeatable performance during the valve’s life.

The LincolnLog valve offers reliable, long-term performance
in the most extreme applications such as inaccessible
high-pressure, liquid-letdown, wellhead-injection valves.
The LincolnLog anti-cavitation control valve can be custom
engineered with as many as 10 stages of pressure reduction
for applications with extreme pressure drops in excess of 8000
psi (550 Bar). These valves control the pressure drop
in multiple stages for confident operation in remote
locations such as offshore platforms. Furthermore,
a flexible range of staging ratios is available to
customize the pressure drop for a wide variety of
fluids and conditions.

Multi-Stage, Axial Flow Technology

High trim velocity can intensify cavitation damage inside the
control valve. This damage is common in many single-stage
valve designs, which take the full pressure drop across a single
region within the trim. This single region is typically the lead­ing edge of the plug and seat — an area that experiences the
highest velocity. Consequently, it receives the most severe and
excessive damage.

Similarly, many radial trim designs, such as drilled- hole cages
and stacked disks, often experience the same fate under
extreme pressure drops. Unlike the axial flow design of the
LincolnLog valve, many radial designs throttle the pressure
drop at the innermost radial stage adjacent to the plug-seating
surface. When this radial trim is only partially open, the outer­most stages are oversized, essentially becoming inactive and
voiding any intended staging. In this case, the full pressure
drop is taken across the final stage, resulting in high energy
release right at the controlling and seating surface of the plug.

In contrast, the axial flow design of the GE Oil & Gas;s
LincolnLog valve offers reliable performance throughout the

entire range of plug travel. By throttling at all stages in

unison, the LincolnLog valve reduces short-circuiting of any
pressure-reduction stage, decreasing wear along the lead-

ing and controlling edge of the plug. The axial flow

technology of the LincolnLog valve helps eliminate

damage to any controlling surface (plug, cage or

seat) by not exposing any one stage to excessive

velocity or the full pressure drop.

Reliability in Service Life

Reliable Installed Life

The LincolnLog valve is repeatedly applied in some of the most
severe liquid service applications because of its robust design.
Some of the most challenging control valve applications
require the LincolnLog valve’s ability to reduce cavitation while
withstanding direct impingement from metal, sand or other
abrasive particles traveling within the process fluid.

For applications such as wellhead chokes and reclaimed oil
processing, the LincolnLog valve reduces particle impact
damage by minimizing the trim velocity through its high­impedance tortuous flow path. Additionally, hardened materials
such as 440C stainless steel and solid tungsten carbide are
successfully incorporated into the trim design to further
withstand erosive attack. For these applications, the LincolnLog
valve offers a reliable and long-lasting solution by combining
hardened materials with a low velocity, multi-stage, anti­cavitation design.

Vibration is also a cause of premature valve- trim part failure –
specifically, the valve plug and stem. Vibration can be process
induced or can be caused by the throttling effects of very high­pressure, liquid-flow streams. The LincolnLog valve features
oversized stem and guiding areas to overcome premature
failure due to vibration. The oversized stem is mated to the
plug with a unique male-female coupling configuration that
positively aligns the plug and stem. This reduces fatigue failure
due to vibration caused by trim misalignment. Secure guiding
extends across the full length of the valve plug, as continuous
plug guides are present in each of the staged reduction areas.

Reliability in Control

Reliable Valve Control

The axial flow technology of the LincolnLog valve offers
a smooth control characteristic across the entire range
of operation. Each pressure reduction stage is throttling
simultaneously across the plug, thus avoiding the stair-stepped
control response that is commonly found in valves with radial
flow designs. The smooth and continuous throttling control of
the LincolnLog valve is achieved by the notches, or stages, in
the plug design. The unique notched design coupled with the
staged liner and cage enables the LincolnLog valve to control
process conditions over an extremely large range of operation
— in some applications up to a 150:1 turndown ratio.

As an added feature, the enlarged flow passages of the axial
flow design help protect the trim from clogging with pipeline
debris. This inherent “debris- tolerant” feature offers the benefit
of uninterrupted service and repeatable control, which helps set
the LincolnLog valve apart from the competition. Applications
such as Pump Recirculation rely on this technology to promote
continuous flow passing through the pump, helping to prevent
burn-out or overheating of this critical piece of equipment.
The LincolnLog valve can be applied in this service as flow will
continue to recirculate with no risk of interruption resulting
from blocked flow passages.

Continuously Active Stages

GE Oil & Gas’s smart instrumentation including the SVIII AP
(HART® digital positioner) and the FVP (FOUNDATION Fieldbus™
Positioner) allow for greater sensitivity and increased control
accuracy. Our digital positioners also increase the repeatability
and reliability of the control valve assembly, allowing for the
precise control enabled by 1/10,000th of an inch plug travel
resolution. Both positioners are available in single- or double­acting configurations.

Reliability in Service Life

Reliable Installed Life

Many valve applications result in poor shutoff or excessive seat
leakage after short-term use because the seating area also
serves as the primary control element. Designs that throttle
the flow near the seating surfaces often experience high fluid
velocity in this region and direct the pressure drop across
the leading edge of the plug and seat. Once early signs of
erosion or wire drawing develop on the seating surface, quick
deterioration of valve shutoff performance follows as a result
of the high pressure drop condition.

The Masoneilan LincolnLog valve is configured to maintain
long-term shutoff by separating the two functions of shutoff
and control into separate areas within the trim. As the plug lifts
off the seat, fluid begins to fill the first plug chamber until the
valve is approximately 15 percent open. With continued travel,
the downstream stages begin to open and the fluid is throttled
using the remaining trim stages. Thus, the seating surfaces
are never used for throttling at low flow, which commonly
produces erosion damage in radial flow designs. This seat
protection feature is critical for process startup valves since
they are typically used to throttle high upstream pressure
down to near vacuum conditions for downstream deaerators
or condensers at low plant loads.

Tight Shutoff Designs

Shutoff performance consistent with ANSI/FCI Classes IV, V, and
VI, as well as MSS-SP-61, is available with the LincolnLog valve.
For temperatures up to 600 °F (316 °C), we offer a TFE-inserted,
soft-seat design for tight shutoff. This soft seat is protected by
a sliding metal collar that shields the TFE from direct exposure
to the flow stream and erosive particles when the valve is
open.

Maintaining long-term shutoff is critical in high-pressure
liquid service, as high-pressure differential leakage may lead
to wire drawing, cavitation, or flashing damage to the valve,
downstream piping, or other equipment.
