Introduction

1.1 Introduction

Alpha-I
is a valve sizing tool that performs sizing calculations for DeZURIK
control valves based on your process conditions. The calculated data will
provide the information required by the user in selecting a suitable
valve for the process conditions input. After the sizing calculations are completed, Alpha-I
is able to predict the system characteristic and calculate the valve’s
installed characteristic. The installed characteristic graph visually displays the
relationship between flow rate and percentage open of the valve
based on your process conditions.

The program was developed by DeZURIK
to provide accurate valve sizing data based on ISA/Industry formulas.

Alpha-I was designed with the user interface in mind.
Selection for fluids, units, pipe and valve data are window driven. Process
information for a maximum of four conditions can be entered on one screen. All
process conditions are calculated simultaneously. Warning messages are displayed
to indicate when a potentially undesirable situation occurs.

Process Fields

2.5 Process Fields

Figure 1 below illustrates the process fields.


Figure 1.

Flow Rate
 Required field when
solving for Cv or Pressure Drop and must be a positive number.

 

Throttling Cv
 Required field when solving for Flow Rate or
Pressure Drop. Must be a positive number and less than or equal to the
100% Cv value.

 

 

Inlet Pressure
Can be entered in absolute or gauge values for
all units. The selection of absolute or gauge units is made on the Size Valve
tab.

 

Pressure Drop
Required when
solving for Cv or Flow. Must be a positive number. When sizing with vacuum
conditions, the Inlet Pressure is usually equal to atmospheric pressure
and the Pressure Drop is equal to the amount of vacuum you are trying to
achieve. Pressure Drop is not a gauge or absolute value. It is the
difference between two gauge or two absolute values.
Temperature
The absolute value of Temperature
entered must be a positive number. If the Temperature values entered are °F or
°C, the value entered may be a negative number. For Gases and Liquids, the
program uses Temperature to calculate the fluid’s physical constants required
for sizing. The equations used have a temperature range for which the
calculations are deemed accurate. If the temperature input is out of this range,
the program will notify you and provide the calculated values. To insure
accurate sizing, you should check the fluid physical constants
calculated.
Fluid Constants
The three fields immediately following
Temperature are physical constants of the selected fluid which are
required for sizing the valve. Based on the type of fluid selected, the
fluid constants are: Specific Gravity, Vapor Pressure, Critical Pressure,
Compressibility, Specific Heat Ratio, Specific Volume or Specific Weight.
For known fluids, these values are normally calculated. If for some reason
they cannot be calculated, the program will leave the field blank and the
user must enter the value to continue sizing the valve. In all cases,
fluid constants must be positive numbers. Other checks are made on the
values to determine if they are valid for sizing.

 

Cutting, Copying and Pasting Process Data
Process data can be copied and pasted into another
column. To copy data, position the mouse cursor and click the left mouse
button over the field that is to be copied. If more fields are desired
continue holding the left mouse button and drag the selection over the
fields that are to be marked for copying. Once the fields are marked right
click in the marked area and select copy. To paste the fields, left click
in the column that is to be the target of the past. Right click and select
paste. The values will be placed in the appropriate cells. The standard Ctrl-X (cut),
Ctrl-C (copy) and Ctrl-V (paste) shortcut keys also work within the process
fields.

Tag Information
Valve Tag #:

The Valve Tag Number Field is used to identify the
valve for saving and recalling sizing information. It is recommended you define
the Valve Tag Number when you first start the sizing process. The Valve Tag
Number can be defined by selecting New Tag from the File Menu on the Menu Bar or
by selecting the New Tag Icon (written page) which is the second Icon from the
left on the Tool Bar. Using either of these selections will cause the New Tag
dialogue box to appear. The user may type the Valve Tag Number into the field in
the dialogue box. To select a previously saved Valve Tag #, click anywhere in
the Valve Tag # Box. A list of saved Valve Tag Numbers will drop down. Select
the desired Valve Tag Number and all sizing data previously saved under that
Valve Tag Number will appear.

Service:

Service is a user defined field. The contents of the
field have no bearing on the operation of the program. It is provided to aid the
user in describing the purpose of the valve and is printed on both data sheet
printouts.

Specification:

Specification a user defined field. The contents of
the field have no bearing on the operation of the program. It is provided to aid
the user in describing the purpose of the valve and is printed on both data
sheet printouts.

 

 

 Fluid Data
Type:Fluid Type allows the user to select
the type of fluid for which the valve will be sized. Alpha-I has equations
to size for four types of fluids: Liquid, Gas, Steam and Pulp Stock. To
select a Fluid Type, click anywhere in the Fluid Type Box. A list of the
Fluid Types will drop down. Highlight the Fluid Type you desire and click
on it.

Name:

For each Fluid Type, Alpha-I knows the
fluid data required for a number of fluids. To select one of the known
fluids, click anywhere in the Fluid Name Box. A list of known fluids will
appear. Highlight the desired fluid and click on it. If you have selected Gas or Liquid
as the Fluid Type and the fluid you need is not in the Fluid Name list you
can either select the closest fluid from a physical property standpoint or you
can select “Other Liquid” or “Other Gas”. If “Other Liquid” or “Other Gas” is
selected, you will be required to input all the physical fluid constants required
for sizing. In many cases if you have a liquid slurry, you can select the fluid
that is transporting the slurry and adjust the Specific Weight or Specific
Gravity in the Process Conditions to account for the affects of the slurry. Fluid
Name is not active until the Fluid Type is selected. If you have suggestions
for fluids that would be valuable additions, contact DeZURIK with the
appropriate fluid physical properties so they can be added to future
versions.

Stock Consistency:

If the Fluid Type Selected is Pulp Stock, this box
will become active. Type the percent consistency of the pulp stock into this
field. If you have 3% consistency, enter “3” not “0.03” into this field. Alpha-I
has correction factors for consistency values <= 12%. The Stock Consistency
Factor will be applied to all conditions.

Other Fluid:

If “Other Gas” or “Other Liquid” is selected, this
field will become active. Enter the name of the fluid being sized into this
field.

 

 

 Units
Flow:To minimize conversions, Alpha-I provides options for
multiple Flow Units for each Fluid Type. To select a Flow Unit, click anywhere
in the Flow Unit Box. A list of Flow Units will drop down. Highlight the Flow
Unit you desire and click on it. The Flow Unit Box is not active until the Fluid
Type has been selected.

Pressure:

To minimize conversions, Alpha-I provides options for
multiple Pressure Units. To select a Pressure Unit, click anywhere in the
Pressure Unit Box. A list of Pressure Units will drop down. Highlight the
Pressure Unit you desire and click on it.

Temperature:

To minimize conversions, Alpha-I provides options for
multiple Temperature Units. To select a Temperature Unit, click anywhere in the
Temperature Unit Box. A list of Temperature Units will drop down. Highlight the
Temperature Unit you desire and click on it.

Diameter:

To minimize conversions, Alpha-I provides options for
multiple Diameter Units. To select a Diameter Unit, click anywhere in the
Diameter Unit Box. A list of Diameter Units will drop down. Highlight the
Diameter Unit you desire and click on it.

 

 

 Pipe Data
Inlet Size:Alpha-I can size valves that range in size from ¼ –
72″ (15 – 1800 mm). Calculations take into account when the pipe size and valve
body size are not the same. To select an Inlet Pipe Size, click anywhere in the
Inlet Size Box. A list of Inlet Pipe Sizes will drop down. Highlight the Inlet
Pipe Size you desire and click on it. Inlet Size field is not active until the
Diameter Units have been selected.

Outlet Size:

Alpha-I can size valves that range in size from ¼ –
72″ (15 – 1800 mm). Calculations take into account when the pipe size and valve
body size are not the same. To select an Outlet Pipe Size, click anywhere in the
Outlet Size Box. A list of Outlet Pipe Sizes will drop down. Highlight the
Outlet Pipe Size you desire and click on it. Outlet Size field is not active
until the Diameter Units have been selected.

Outlet Schedule:

Alpha-I has data stored for many Schedules of Outlet
Pipe Sizes. To select an Outlet Pipe Schedule, click anywhere in the Outlet
Schedule Box. A list of Outlet Pipe Schedules will drop down. Highlight the
Outlet Pipe Schedule you desire and click on it. Outlet Schedule field is not
active until the Diameter Units have been selected. The Outlet Pipe Schedule is
used exclusively in calculations for Predicted Noise Level.

Outlet Diameter:

Based on the Outlet Pipe Size and Schedule selected,
Alpha-I will display the Outlet Pipe Diameter if known. If it is not known, the
field will display a 0 value and the user will need to enter a valid diameter
before sizing calculations can be performed.

Outlet Thickness:

Based on the Outlet Pipe Size and Schedule selected,
Alpha-I will display the Outlet Pipe Thickness if known. If it is not known, the
field will display a 0 value and the user will need to enter a valid thickness
before sizing calculations can be performed.

Outlet Pipe Insulation:

Insulation is a path treatment for noise. It does not
prevent the creation of noise, it prevents the noise from reaching an undesired
location. Path treatment should be used with caution as excessive noise can be
detrimental to the valve and piping system. Path treatments are only effective
as long as the treatment exists. When using insulation as a path treatment, the
reduction in noise is only effective for the length of pipe that is insulated.
If the pipe insulation stops, the noise reduction also will stop. Noise will
propagate down the pipeline for many pipe diameters. Alpha-I allows you to
select two types of insulation, thermal and acoustical of varying thicknesses.
The reductions in noise are average values and will be affected by the frequency
of the noise.

 

 

 Valve Data
Style:Alpha-I can size for many styles of
DeZURIK Control Valves. Before any calculations can be performed, the Style of
valve desired must be selected. To select a Valve Style, click anywhere in the
Valve Style Box. A list of Valve Styles will drop down. Highlight the Valve
Style you desire and click on it. Selecting “Apply Filters” as the Valve Style
will direct Alpha-I to size for all valves meeting the criteria selected in the
Filter Setup dialogue box. Refer to section 2.9 for additional information on
filters and multiple valve sizing.

Size:

Alpha-I can solve for three variables: Cv, Flow and
Pressure Drop. What to solve for is selected from the Menu Bar; Solve for Cv is
the default selection and will be selected every time the program is started.
When solving for Flow or Pressure Drop, the Valve Size field is required. When
solving for Cv, the Valve Size field is optional. A powerful feature of Alpha-I
is its ability to size for the smallest body size for the selected Valve Style
based on the process conditions input. To let Alpha-I automatically size for the
smallest valve body size, select the Valve Style and leave the body size field
and all other fields in the Valve Data Group blank when you perform the
calculations. Alpha-I’s autosize feature will never select a body size less than
¼ of the Inlet Pipe Size. You can manually select body sizes less than ¼ of the
inlet pipe size and Alpha-I will perform the sizing calculations. To select a
Valve Size, click anywhere in the Valve Size Box. A list of Valve Sizes based on
the Valve Style selected will drop down. Highlight the Valve Size you desire and
click on it. To clear the Valve Size Field, go back to the Valve Style Field and
re-select a Valve Style. Valve Size will not be active until Valve Style has
been selected.

Trim Characteristic:

The “Trim Char” Field contains the Trim
Characteristics available based on the Valve Size selected. The “Trim Char”
field is not active until Valve Style & Size have been selected. To select a
Trim Characteristic, click anywhere in the “Trim Char” Box. A list of Trim
Characteristics available, based on other Valve Data selected, will drop down.
Highlight the Characteristic you desire and click on it. If only one Trim
Characteristic is available for the Valve Data previously selected, it will be
automatically displayed. To clear the Trim Char Field, go back to the Valve Size
Field and re-select a Valve Size.

Trim Style:

The Trim Style Field contains the Trim Styles
available based on the Valve Data previously selected. The Trim Style field is
not active until all Valve Data fields preceding it have been selected. To
select a Trim Style, click anywhere in the Trim Style Box. A list of Trim Styles
available, based on other Valve Data selected, will drop down. Highlight the
Style you desire and click on it. If only one Trim Style is available for the
Valve Data previously selected, it will be automatically displayed. To clear the
Trim Style Field, go back to the Trim Char Field and re-select a Trim
Characteristic.

Trim Size:

The Trim Size Field contains the Trim Sizes available
based on the Valve Data previously selected. The Trim Size field is not active
until all Valve Data fields preceding it have been selected. To select a Trim
Size, click on the arrow in the Trim Size Box. A list of Trim Sizes available
based on the Valve Style & Size selected will drop down. Highlight the Size
you desire and click on it. If only one Trim Size is available for the Valve
Style and Size selected, it will be automatically displayed. To clear the Trim
Size Field, go back to the Trim Style Field and re-select a Trim Style
Size.

100% Cv

The 100% Cv field will display the Cv value with the
valve 100% open. It is displayed when all the fields in the Valve Data group are
filled in.

 

Calculated Fields

2.6 Calculated Fields

Calculated fields
display the values that are calculated base on the static and process field
values entered. The fields are read-only. Figure 1 below illustrates the calculated fields.


Figure 1.

 

Flow Rate
Calculated based on
equations provided in ISA-S75.01-1985 (R1995) standard.  Factors for Pipe Reducers
(Fp) are included. When the Fluid Type is Pulp Stock, consistency
correction factors developed by DeZURIK are applied.

 

 

Pressure Drop
Calculated based equations provided in
ISA-S75.01-1985 (R1995) standard.  Factors for Pipe Reducers (Fp) are
included. When the Fluid Type is Pulp Stock, consistency correction
factors developed by DeZURIK are applied.

 

 

Cv
Calculated based equations provided
in ISA-S75.01-1985 (R1995) standard.  Factors for Pipe Reducers (Fp)
are included. When the Fluid Type is Pulp Stock, consistency correction
factors developed by DeZURIK are applied.

 

 

Position Open
Determined by
comparing the Cv calculated (or input when sizing for Flow or Pressure
Drop) versus the actual Inherent Cv curve of the specific valve selected.

 

 

 Inlet Velocity
Calculated for
Liquids, including Pulp Stock, and is based on the nominal inlet size of
the valve selected.

 

 

Outlet Velocity
Calculated for Gas and Steam.
The calculation is based on the nominal diameter of the Outlet Pipe Size. The
calculation is displayed as a Mach velocity which is the ratio of the fluid
velocity to the sonic velocity of the fluid.

 

 

Special Conditions
Identified in
the program are Critical Cavitation and Flashing for Liquid and Choked
Flow for Gas and Steam. If any of these conditions are present, the
program will display them in bold red letters. When critical flow occurs
in liquids, part of the liquid is actually changing state from a liquid to
a vapor and then back to a liquid again. This is known as cavitation. The
change in state from the vapor back to the liquid can be very damaging to
the valve or downstream piping and should be avoided if  possible.
When critical cavitation occurs in liquid flow, the formation of the vapor
takes up a substantial volume in the valve body / trim. This additional
volume “chokes” the valve, limiting the flow. Once this point is reached,
an increase in flow cannot be achieved by increasing the pressure drop.
When choked flow occurs in gas or steam, the gas or steam does not change
state. Choked flow in gas or steam indicates that the pressure in the
vena-contracta (typically the location in the valve body / trim right
after the valve orifice) has dropped low enough that the expansion in the
gas or steam at this low pressure has taken up so much additional volume
that is has “choked” the valve, limiting the flow. Like liquids, once this
point is reached, an increase in flow cannot be achieved by increasing the
pressure drop. Unlike liquids, choked flow in gas or steam is not a good
damage indicator. In many cases damage will not occur when gas or steam
achieves choked flow. A much better indicator for damage in gas or steam
is the predicted noise level or outlet velocity.

 

 

Pressure Drop Ratio
Calculated for
Gas and Steam. This is the ratio of the Pressure Drop to the absolute
Inlet Pressure.

 

 

Incipient Pressure Drop
Calculated for
Liquids, including Pulp Stock. This defines the measurable onset of
cavitation as it begins to affect the capacity of the valve. Incipient
Pressure Drop is not included in the ISA S75.01 standard, but is
recognized in the valve industry.

 

 

Critical Pressure Drop
Calculated for all fluid types based
on ISA S75.0-1985 (R1995) equations. It defines the pressure drop at which
flow will or has become limited across the control valve for the given
process conditions.

 

 

Predicted Noise
Calculated based
on industry equations. The calculated noise is at a distance three feet
downstream of the control valve and three feet from the outside pipe wall.
It does not take into account any factors due to insulation, reflective
surfaces, or non-standard piping. It does take into account the Outlet
Pipe Diameter and Wall Thickness.

Filters and Multiple Valve Sizing

2.7 Filters and Multiple Valve Sizing

A powerful
feature of Alpha-I is the ability to size for multiple valves and filter the
criteria used for selecting which valves are selected for sizing. There are two
types of filters. Input filters limit which valves Alpha-I selects from the data
base to try to size for the process conditions entered. Output
filters are used to limit which valves are displayed based on calculated results
other than Cv.

Input filters include valve style and valve body
size. Valve styles can be selected individually from the scrolling list or in
groups. If a valve style or group is selected (a check mark is present) Alpha-I
will size for that style or group of valves when Apply Filters is selected from
the Valve Style input field. If the style or group is not selected, Alpha-I will
not size for that valve or valve group. Valve body size can be limited to the
same size as the inlet line size or for all body sizes from 1/2 of the inlet
line size to the inlet line size.

Output filters include position open, predicted noise
level, inlet body velocity and special conditions. If an output filter is set
and a valve meets the capacity requirements of the process conditions but does
not meet the conditions of the output filter for at least one process condition,
that valve will not be displayed in the Filtered Valve List.

Multiple Valve Sizing

To size for multiple
valves, enter all static and process data as you normally would. In the
Valve Data Group, select Apply Filters as the Valve Style as shown in Figure 1.


Figure 1.

When Perform
Sizing Calculations is clicked, Alpha-I will display the Filter Setup dialog shown in Figure 2.


Figure 2.

Select the desired filter values and click
Ok. The Filter Setup dialog is displayed each time the Valve Data Style is set
to “Apply Filters”. The previously selected values are used the next time the
Filter Setup dialog is displayed.

Filtered
Valves dialog box is then displayed. In this box, all valves that meet
the process conditions input based on flow
capacity are displayed. The results for each process condition entered can be viewed by
selecting the appropriate condition from the tab at the top of the dialog
box. Click on the desired valve to highlight it and click ok select the
valve.


Figure 3.

Alpha-I filters valve styles based on flow capacity
only. It does not take such items as temperature or pressure class of valve into
consideration.

For most sizing problems, the list of valves
displayed in the Filtered Valve List dialog box will be excessive. To narrow the
list of valves, Alpha-I allows you to filter the results based on the type of
valve, line size preference and specific output calculations.

Managing Data Projects

3.1 Projects

The section
describes how to create new projects, save projects and open existing
projects.

Create New Projects
When Alpha-I is started it initially creates an
empty and unsaved project. The project is untitled and is the starting point for any new
project. Figure 1 shows the title bar of a new project.


Figure 1.

 New tags can be created and valves can be sized using
the untitled project. To have the ability to recall a project it must be saved. This is accomplished by clicking on the [Save…]
button in the Project tab. If this is the first time the project has been saved a Save
As dialog will prompt for a project name and location.

A new
project can be create a by clicking on the [New] button in the
Project tag found in the File group.

Open Projects
Saved project can
be opened by selecting [Open] button in the Projects tab found in the File
group. This will bring up an open file dialog which can be used to browse to
project files.

How Sizing Data is Saved

3.3 How Sizing Data is Saved

Alpha-I saves sizing data in a file with the
extension .alphaI. One project can hold practically unlimited Tag Numbers. The
Tag Number must be unique as it is used to differentiate between tags.

Backing Up Sizing Data

3.5 Backing Up Sizing Data

Backing Up sizing information only requires backing
up the project file with the “.alphaI” extension. You should not need to back up
the Alpha-I program software as this can be reloaded if necessary.

How to Transport Sizing Data

3.4 How to Transport Sizing Data

To transport information from one machine to another,
all that is required is to move the appropriate project file with the “.alphaI”
extension. Both machines must have a copy of the Alpha-I software loaded.

Deleting Projects

3.6 Deleting Projects

Valve Tag Numbers can be deleted from within the
Alpha-I program. Project files cannot be deleted from within the Alpha-I
program. To delete an Alpha-I project, delete the Project file with the “.alphaI”
extension outside of the program.
