5 Terms

This chapter shall introduce you with the main terms which are used in VALVESTAR®. 5.1 Projects

Several projects can be active and loaded at the same time. Projects are the folders containing the sizings and all projects-depending information.

5.2 Sizings

Sizings are depending on codes/standards and consisting of service conditions, medium-data and valves.

5.3 Valves

A valve consists of approval data, connections, part lists, drawings etc. A valve can be configurated according to the customer requirements. One or more valves may be added to one sizing. On the one hand they have the characteristics for the calculation (depending from the code). On the other hand valves may include technical information concerning the design. E.g. you can choose a steel-bellow or an O-ring-disc. These configurations may influence the calculation (e.g. liftrestriction).

Wizard

Whenever you create a new sizing or project, a wizard will guide you to proceed the task.

6 Quick start

This chapter will introduce you the main features of VALVESTAR®. We will create a new project and a sizing for saturated steam according to AD 2000: A2. We will select a safety valve and configure the inlet and outlet connections. Finally we will create the documentation in pdf-format.

6.1 Create project

You can create a project from the Welcome dialog by selecting Create new sizing or from menu by selecting Sizing -> Add Sizing. A new screen appears (Figure 2, wizard is guiding you)

Figure 1 Welcome dialog

Figure 2 Create new sizing wizard



continues on page 7



Click next button to proceed. In the next screen you can specify the tag number, the medium the available sizing standards for the medium and use standardized units. There are also additional calculations available (e.g. reaction force, ….) which may by chosen to each standard.

After clicking the next you can type in the service condition. Those fields, which require input data are marked red. When you move the mouse into those red fields a balloon control pops up and informs you about restrictions.

We choose the following service condition: Set pressure 10 bar-g Constant back pressure 0 bar-g Overpressure 10 % Required massflow 10.000 kg/h



continues on page 8



We select steam data according to DIN EN ISO 4126-1. VALVESTAR® calculates the saturation temperature: 188°C, the isentropic exponent k=1,14 and the specific volume v=0,163m3/kg.

The next task is to find an appropriate valve. Therefore you can specify valve parameters in the Valve finder



continues on page 9



The more selective your parameters are, the faster will be the calculation of VALVESTAR in the next screen. In the Valve selection screen are all safety valves shown, which meet the requirements from the Valve finder. In the left upper screen you can select the type, in the right upper screen the body material and the lifting device. VALVESTAR pre selects the appropriate safety valves based on the capacity exceed. You can choose a different valve by clicking on the row and pressing the select button. VALVESTAR then loads the complete valve data from the data base depending on your computer this may take up to 5 seconds.

After you have selected a valve you may configure it according your requirements. First you can change the inlet and outlet connections. Whenever additional input data are available they are stored in list controls e.g. pressure rating e.g. PR are available #150 and #300.



continues on page 10



The section “valve accessories” allows you the selection of several option codes and you can also specify required inspections.

As a result you find a part list according to your specification. If you select the check box certificate the option code for the corresponding part list position is chosen.






Finally valvestar informs you about dimensional data of the safety valve.

Click Finish button to finish your sizing. After finishing your sizing you get back to the valve explorer. The left part of the screen shows you all projects and sizing of the tree structure. When you double click an option in the tree structure the right part of the screen shows a content of the object.






Finally we want to store project dependent data in our project. We double click on the root of the tree (new project). You can choose a project name and add descriptive data for internal use in the description section. Several additional input fields are available, which can be customized and renamed by you.

We choose a suitable name for our project, add a comment in the internal description and select in the menu Documentation -> Report. VALVESTAR allows you a customization of the reports. You can select the language, unit system (differ from the sizing units) and select only those sections, which you need for your internal reporting. You can output the printout to your printer to pdf or to a preview on the screen. We select preview and a new screen appears. From the preview you can print the document or export it to several different file formats. You will find an example of the printout in the appendix 1.






Congratulations! You have finished your first sizing with VALVESTAR. You will find out that all sizings follow this scheme. The wizard will always support you. For further information about codes and standards please refer to chapter XXXX. In the next chapter you learn more about the user interface and additional functionality of VALVESTAR. 7 The user interface

7.1 Profiles

All initial settings are stored in profiles. It is possible to store several settings in different profiles. The following data is stored in the profiles:

• general data (company and contact data) You may change or create a profile by clicking Profiles -> Default -> Edit.






• User Information

This section contains information about the user (the person who created or changes the sizing). The data is used for history and the short name will be printed on the data sheet.

• Configuration

The configuration section allows you to customize the initial settings of sizings. You can set up an Environmental pressure select country dependent decimal and group separator. Further it is possible to choose the source for steam data. Also you may predefine your default sizing/standard code. At least you can choose between several application modes. We suggest you to choose the standard mode, which will able you to use all calculation features. The professional mode allows you to overwrite standard settings for valves. Deep knowledge of safety valves is needed to use this mode. The super user mode is reserved for LESER and it’s partners.

• Unit Settings

For each code/standard unit presetting is possible. First select the code/standard in the top list box then change the position and unit according your needs.






• Valves types

It may be useful to preselect the body material and the lifting device for each LESER type. This filter will be applied if you leave all fields in the valve finder blanc.

• Volume flow standards

Several volume flow standards are already implemented in the VALVESTAR. Three user defined volume flows are free for your own use.

7.2 Languages

VALVESTAR is delivered with several languages for user interface and data sheets. You can select a different language from the user face menu Tools -> Language -> select a language.






You can select the language for the report from the report options window, which pops up when you select from the menu Documentation -> Report

7.3 Helpful hints

We recommend you to frequently store your work. Please note that you can specify a default folder to store your data. You can use the default cut and paste functionality as you know from other software. You can copy either the project sizing from the valve by marking it with the mouse and click in the menu Edit – Copy and then Paste it in a new structure. VALVESTAR checks whether it is possible to copy an object. It is impossible to copy a valve AD A2000-sizing into ASME sizing because of the different structure of the sizing. 7.4 Loading and saving projects

You can load a project from a file system. Select from a menu File -> Load Project

You can store projects in the same way. It is also possible to use the short keys (Control+O = open project, Control+S = save project). You can also unload and save all active project from the menu. 7.5 Manual valve configuration

7.5.1 Wizard

You can select several accessories and configure the inlet and outlet of the safety valve. This feature is available from the wizard when you create a sizing and from the pop up menu when you right click on the safety valve and select Valve construction. Clicking Valve construction leads you to the wizard. You can go back to the valve selection and exchange the valve (The other way to






exchange the valve would be deleting it with cut-functionality and then right click the sizing and select Add Valve.

Valve connections

In the first step you select your inlet and outlet connection. See page 9 valve connections. First select a flange in the upper part of the screen. Then push the select button to accept the chosen connection. In some cases you may need a connection which is not listed in the possible inlet connections. In this case you can overwrite in the bottom section the selected values. Please take care that this connection is available for you valve.

Valve accessories

The valve accessories window shows all available accessories according to the current price list. You can select accessories in the check boxes in the list control. The part list of the safety valve will be changed according your specification. VALVESTAR checks whether combinations of accessories are possible or not. VALVESTAR is not an ERP System. Because of the complexity of the product, it may be possible that you select with VALVESTAR a combination of the accessories, which is not valid. You may also select one or more inspections. Not all options are listed in our price list. You may add additional options codes with an edit custom button.

Some codes allow lift restrictions. You can choose between standard lift, a calculated lift according your required mass/volume flow or choose manually a lift restriction.

Part Lists

The part list is a result of your configuration. If a certificate is required you may select a check box in the column certificate. The check box is only available for those parts for which a certificate is available.






Please note that Valvestar offers only material part lists without part number. Please contact LESER if you need spare part numbers.

Valve dimensions

The valve dimensions screen shows all dimensions of the safety valve.

7.5.2 How to change manually valve data

Sometimes it is necessary to change valve data manually (e.g. special contructions…). You may use this feature also, if new articles are invented but not yet available in VALVESTAR. Right click on the safety valve and select from the popup menu valve information. Please note that this feature is only available if you work in professional or super user mode.

Now you can overwrite nearly every value (even the article number itself). If you change parameters like discharge diameter depending calculation data will be changed too and applied in the calculation.

As a result it is possible to size any valve with VALVESTAR.

7.6 Reports

7.6.1 Report

The standard report includes all data for the valves and the sizing. You can select the items by checking the boxes with a mouse click.

You may also change the units for the report. As output destination are preview, pdf and printer available. From the preview are export functionalities for several file formats available.






7.6.2 One Page Report

The One Page Report is a condensed report which fits always on one page. You can select a horicontal or vertical design

7.6.3 Project Report

The Project Report is feature which creates a singe excel file with all nessecary information to place an order by LESER. It contains the option code and several valve data. This file is useful for big projects.

7.6.4 Drawings

Valvestar is delivered with a huge number of drawings enabling you to create sophisticated documentation. Please take care that you do not use the drawings to the center to face dimensions. These dimensions should be taken from the report.

7.7 Master Data

The database contains master data from LESER valves, flanges, medium data etc. LESER took great care to ensure the correctness of these data. Please handle all displayed data with care. VALVESTAR allows you to change several data manually which influence data like center to face dimensions (e.g. manually changed connections), discharge coefficients…






8 Menu

The menu is context sensitive. It appears different depending from the chosen icon in the valve explorer. A project report is only available if a sizing or a project is selected. The One Page report is only available if a valve is selected. Other items are always displayed like Medium, File… 9 The Toolbar

The following icons are useful short cuts to advanced functionality:

– Create a new Project

- Open an existing Project

- Save Project

- Cut selected item

- Copy selected item

- Delete selected item

- Insert item

- Create Sizing

- Display Inspections and Certificates

- Add valve

- Valve Info

- Steam Properties






10 Inlet- and Outlet Calculations

10.1 Inlet Calculation

The inlet calculation is available in the wizard as shown below:

After you selected the valve (like in standard sizing) you are asked to specify the pipe. You may select optionally components and define the straight pipe.






The next screen is a combination of maximum length and minimum diameter calculation.Valvestar calculates for several diameters (dependent from the inlet of the valve) the maximum length of the given diameter.

When you select a pipe it is possible to specify the length of the pipe. Valvestar will then calculate the pressure drop for the selected pipe.






10.2 Outlet Calculation

The outlet calculation is similar to the inlet calculation. A new feature enables you to calculate different pipes with diameters.

The Effective pipe resistance is calculated according to german standard AD 2000 A1. You may add a pressure drop from a silencer (which is added to the built up back pressure). It is possible to add components for each diameter by clicking the Edit – Button. A new Window appears.

You can select several components. The ζ-value for the pipe bends are calculated according a Formula from W. Witte. You may overwrite the values if you want to use other values.



End of LWN



10.3 Fire Case

The Fire Case is available only for gas calculations. It is assumed that either a gas is stored in vessel or a liquid with a liquid height below the height of the vessel. The flow is assumed as gaseous (one phase) flow. Select gas as medium when you begin with a sizing. Select Fire Case in the checkbox.

Select as usual the medium and click next. Now you are asked to select the wetted or unwetted surface calculation.

The two methods will be represented in single chapters.
