Insert Instrument Valves (Control Valves)

General points on the procedure are given under Insert Symbols.

Instrument valves behave as for general valves except that they have a mandatory label balloon and an optional link line attached. If necessary, the label balloon can be independently positioned and moved after the instrument valve has been placed, and the point at which it connects to the valve changed.

Functionality is available to insert instrument valves without the mandatory label balloon, instead the instrument valves are annotated using the Tag field value.

Instrument valves can be inserted in two ways:

• By inserting a symbol from the Instrument Valves symbol category consisting of a valve body and an actuator.

• By inserting a symbol from the Valves symbol category, consisting of a valve body, then adding an actuator symbol or symbols to it to make it an Instrument Valve.

Handwheels also fall within the Instrument Valve symbol category, and may be inserted onto instrument valves. Only one handwheel may be placed on an Instrument Valve.

Where an instrument valve is placed between the end node of one pipe, and the start node of another, this valve may serve as the source and destination of the labels of these pipes, as opposed to the pipe nodes, depending on the type of valve that it is.

Note: Instead of inserting symbols, new symbols can be placed on the drawing by copying and pasting existing symbols. Refer to Copy Drawing Objects and Labels.

Example

Errors

An error message will be received if an attempt is made to put two handwheels on the same control valve.

Associated Project Configuration Options

• Whether or not multi-vertex leader lines may be used to connect label balloons with instrument valves is controlled by the Use Multi Vertex Leader Line checkbox in the Instruments – Settings Sub-Category of the AVEVA P&ID Project Administration program.

• The block name of the instrument label balloon symbol is specified in the Label Balloon Symbol field in the Instruments - Labels Sub-Category.

• The presence or absence of link lines is controlled by the Label Balloon Link-Lines Off checkbox on the same pane.

• Instrument valve symbols may be restricted so that they can only be inserted into pipes with specific codes and sizes. These are specified using the Spec Driven Configuration Category.

Procedure

Insert a Complete Instrument Valves Symbol

1. To insert a symbol that consists of both a valve body and an actuator, select the Instrument Valves symbol category by using the Symbol Explorer.

2. After the symbol has been selected a 'ghosted' image of the instrument valve will appear on the cross hairs. The Command prompt will display:

   Insertion point:

   Pick a point on a pipe.

   The valve will be inserted, will orientate itself with the pipe and will adopt the correct colour and layer according to project configuration. 3-way valves will automatically orientate themselves correctly when placed on a 3-way pipe intersection.

3. The Command prompt will then display:

   Show side of Actuator:

   Pick a point to indicate which side of the valve the actuator is on.

4. A 'ghosted' image of the instrument balloon will appear on the cross hairs, the Command prompt will then display:

   Insertion point:

   Place 'ghosted' balloon.

5. If link lines between instruments and balloons are on (for example, the Label Balloon Link-Lines Off checkbox is checked in the AVEVA P&ID Project Administration program), the command prompt will then display:

   Indicate point on symbol:

   Press Enter to attach the link line to the insert point of the instrument valve, or place the connection point "manually" by clicking on the required point.

6. The Command prompt will then display:

   Insertion point:

   Pick another point, or press Ctrl-C to end the command.

Insert a Valve Symbol then add Actuator Symbols

7. Select a valve symbol by using the Symbol Explorer.

8. After the symbol has been selected a 'ghosted' image of the valve will appear on the cross hairs. The Command prompt will display:

   Insertion point:

   Pick a point on a pipe.

   The valve will be inserted, will orientate itself with the pipe and will adopt the correct colour and layer according to project configuration. 3-way valves will automatically orientate themselves correctly when placed on 3-way pipe intersections.

9. The Command prompt will then display:

   Insertion point:

   Pick a point for another valve, or select Cancel from The Drawing Page menu or press Ctrl-C to end the command.

If auto-labelling is on, the Label General Valves procedure will then start automatically.

10. Select an actuator symbol by using the Symbol Explorer.

    In the Symbol Explorer, actuator symbols are located in a sub-folder of the Valves folder.

11. After the symbol has been selected a 'ghosted' image of the actuator will appear on the cross hairs. The Command prompt will display:

    Insertion point:

    Pick a valve.

    Note: You can add multiple actuator symbols to the same valve body symbol.

12. If the valve has been inserted into a vertical line, the Command prompt will then display:

    Get angle:

    Pick a point to indicate which side of the valve the actuator is on.

    The actuator will be inserted on the selected valve, will orientate itself with the valve and will adopt the correct colour and layer according to project configuration.

13. A 'ghosted' image of the instrument balloon will appear on the cross hairs, the Command prompt will then display:

    Insertion point:

    Place 'ghosted' balloon.

14. If link lines between instruments and balloons are on (for example, the Label Balloon Link-Lines Off checkbox is checked in the AVEVA P&ID Project Administration program), the command prompt will then display:

    Pick a point on symbol:

    Press Enter to attach the link line to the insert point of the instrument valve, or place the connection point "manually" by clicking on the required point.

15. The Command prompt will then display:

    Insertion point:

    Pick a valve for another actuator, or select Cancel from The Drawing Page menu or press Ctrl-C to end the command.

Add a Handwheel

16. Add a handwheel to an Instrument Valve by using the Symbol Explorer.

17. When a handwheel has been selected, the command prompt will display:

    Insertion point:

    Pick the instrument valve.

18. The Command prompt will then display:

    Get angle:

    Pick a point to indicate which side of the valve the handwheel is on.

19. The Command prompt will then display:

    Insertion point:

    Attach a handwheel to another valve, or select Cancel from The Drawing Page menu or press Ctrl-C to end the command.

If auto-labelling is on, the Label General Instruments procedure will then start automatically.

Insert an Instrument Valve without the mandatory Label Balloon

20. Create an instrument valve symbol using the Symbol Editor.

21. Right-click on the symbol and select Edit Properties from the menu to display the Edit Properties window.

22. Select INS from the the P&ID Type drop down list.

    

23. Save and close the instrument valve symbol.

24. Select the required instrument valve symbol by using the Symbol Explorer.

25. After the symbol has been selected a 'ghosted' image of the instrument valve will appear on the cross hairs. The Command prompt will display:

    Insertion point:

    Pick a point on a pipe.

    The valve will be inserted, will orientate itself with the pipe and will adopt the correct colour and layer according to the project configuration.

    

26. Right-click on the symbol and select Properties from the menu to display the Instrument Properties window.

    

27. Modify the values designed to toggle the insertion of individual attributes that are part of the instrument tag (values of Yes/No), it is expected the user will choose to annotate the instrument valve using the Place Component Tag field.

    The instrument valve is annotated with the Tag field value at the location specified in the project configuration.
