High Pressure Anti-Cavitation Control Valves

Contents
The Masoneilan LincolnLog is the premier high-pressure
liquid letdown valve in the process control industry. It
is a field proven severe service solution for cavitating
and erosive applications in various industries. The
LincolnLog is uniquely designed to operate reliably
in harsh environments and dirty liquids. Key design
features of the LincolnLog include:
Cavitation Elimination
The multi-step flow path created by the LincolnLog trim
design, reduces the pressure drop in multiple stages
without allowing the local pressure to drop below the
fluid vapor pressure thus preventing cavitation. These
active stages throttle in unison to avoid taking the full
pressure drop across any individual stage.
Dirt Tolerant
Wide flow paths in the LincolnLog allow free passage of
large particles through the unique trim and body design
without causing any damage or loss of capacity. This
ensures continuous and efficient operation by
eliminating concerns of potential clogging due to
entrained particles.
The LincolnLog is a proven problem solver in dirty
service applications.
Heavy Plug Guiding
Guiding is provided along the full length of the plug by
a hardened liner, which minimizes any vibration effects
and results in excellent dynamic stability. This helps to
improve product yield through accurate and smooth
process control.
Versatile Trim Options
Standard LincolnLog trim is available in 3, 4 and 6
stages with different staging ratios to cover the vast
majority of high-pressure liquid letdown services.
Masoneilan can also provide engineered solutions
consisting of additional stages to satisfy specific ap-
plication requirements. The LincolnLog is available with
both balanced and unbalanced plug designs for greater
application flexibility.
Protected Seat Design
Overlap is designed into the trim at low lift to keep high
velocity flow away from the valve seat. This helps to
avoid seat erosion and extends the operating life under
high pressure drop conditions.
Reliable Tight Shutoff
Standard seat leakage rating for the LincolnLog meets
IEC 534-4 and ANSI/FCI 70.2 Class V shutoff. An optional
soft seat design provides Class VI bubble tight shutoff.
It includes a patented sliding metal collar design, which
protects the soft seat from extruding and serves as a
back-up seating surface. The LincolnLog can also be
supplied with block valve tight shutoff per MSS-SP-61.
Ease of Maintenance
LincolnLog’s simple top-entry design includes quick
change trim for easy access and removal. The integral
liner and seat ring also reduces the number of compo-
nents and simplifies assembly and disassembly.
NACE and PED Compliance
The LincolnLog is available for Sour Service Applications
using the design and construction methods defined in
NACE Standard MR0103. Product configurations for ap-
plications requiring compliance to MR0175 - 2003 or ISO
15156 are also available upon request. The LincolnLog is
also designed for compliance with Pressure Equipment
Directives (PED) requirements.

Satandard Capacity — 6-Stage Design Flow Characteristic: MODIFIED LINEAR
7
The LincolnLog trim provides a smooth modified
linear control characteristic with “clearance flow”
capacity over the initial 15% of valve travel as shown
in the generic chart and table at right.
Incorporation of the multi-stage “clearance flow”
design concept prevents high pressure drops across
the LincolnLog seating area while throttling at low
lifts. This feature helps to extend trim life signifi-
cantly, resulting in dependable and tight shutoff
whenever required. It also improves the throttling
control stability and performance at low lifts, while
providing smooth, accurate and continuous capacity
control from 15% to 100% plug travel. Controllability
extends from the Maximum Rated CV to the
Minimum Controllable CV for any valve size resulting
in typical turndown ratios of 50:1.
15 - 100% of Plug Travel
There is much greater flow area through
the valve seat versus the plug notches.
As a result, pressure drop and velocities
across the critical seating surfaces are
controlled eliminating seat damage.

Valve Sizing Guidelines
Staging Ratios & Pressure
Drop Guidelines
(1) Staging ratios provide approximations of the relative area ratios for each specific trim type. As an example, a staging ratio of 1-1-2
indicates that the final stage for that trim type has approximately twice the area of the first two stages.
(2) Staging ratios do not have any relative correlation between the different trim types.
(3) Recommended limits for ΔP per stage are 800 psi (60 bar) for continuous duty cycle applications and up to 1000 psi (70 bar) ΔP per
stage for intermittent service.
General
LincolnLog multi-stage control valves can be sized
using either standard IEC/ISA equations or using
the latest Masoneilan sizing and selection software
program.
Noise Predictions
Valve noise calculations can be performed using the
Masoneilan sizing and selection program based on the
latest IEC equations. The serial stage construction of
the LincolnLog design helps to
significantly reduce trim noise. Calculating the
noise at the last stage of the LincolnLog trim
will closely approximate the overall valve noise
produced. Pressure drop across the last stage can be
derived from the table below and used in the noise
calculations.
Trim Selection
As indicated in the table below, the LincolnLog is
available in various standard trim types and number
of stages. Each trim style provides different staging
ratios and different pressure drop percentages per
stage. Recommended limits for ΔP per stage are 800
psi (60 bar) for continuous duty cycle applications and
up to 1000 psi (70 bar) ΔP per stage for intermittent
service. The recommended operating throttling ΔP
limits are also shown in the table below.
Engineered Solutions
For flashing service, the expansion ratio of the fluid
will determine the appropriate staging ratio to apply.
Non-standard staging ratios can be supplied for
compressible two-phase flow or flashing conditions
not covered by the standard trim. Please consult
Masoneilan for proper sizing and design of engineered
solutions for these types of applications.
