Variant for Part Type: 4-Way Valve (PE)

Rules for the creation of Feature Variants for Plant Engineering parts

Position of connecting points and determination of insertion lengths for various connection types
Connection for butt welding	Flange connection	Connecting nipple for screwed, plugged or socket-welded connection	Connecting socket for screwed, plugged or socket-welded connection

a = Insertion length dimension (e.g. L, L1 etc.)	a = Insertion length dimension (e.g. L, L1 etc.)	a = Insertion length dimension (e.g. L, L1 etc.)	a = Insertion length dimension (e.g. L, L1 etc.)

Named isolated points

Designation	Purpose	Comment	Position in coordinate system
!	Connecting point	Fitting point	in origin (0,0,0)
2	Connecting point		X = 0, Y = 0, Z > 0
3	Connecting point	on branch	X > 0, Y = 0, Z > 0
4	Connecting point	on branch	X < 0, Y = 0, Z > 0

Variables names

Name	Description	Attribute (optional)
L	Length of distance between points “!“ and “2“	LAENGE
L1	Length of distance between points “!“ and the intersection point of centre lines	LAENGE1
L3	Half the length of the distance between points “3“ und “4“	LAENGE3

If the variables names given in the Name column are used, you do not need to assign any attributes to them via the Variant Editor. If different variables are required, you need to assign the attributes given in the Attribute column.

VAA file

Use the Variant Editor to enter the suitable part type into the VAA file.

Then, use the Variant Editor to expand the VAA file in such a way that it contains values for the sizes specified here, and that the predefined attribute assignment is entered:

Parameter All dimensions must be specified in millimetres; Exception: Nominal diameters in inches	Variable (suggestion)	Assigned attribute
Nominal diameter, Connection “!“ and “2“	N	NENNWEITE
Nominal diameter, Connection “3“ and “4“	N3	NENNWEITE3

Additionally (only if the corresponding standard uses nominal diameters in inches):
Nominal diameter (inches), Connection “!“ and “2“	NI	N_INCH
Nominal diameter (inches), Connection “3“ and “4“	NI3	N3_INCH
Nominal diameters in inches need to be entered as decimal values as well (e.g. 1.5 for 1 1/2‘‘).

These parameters are to be considered for all connection types except for flange connections. For connecting sockets they refer to the pipe to be inserted:
Outer diameter, Connection “!“ and “2“	D	D_AUSSEN
Outer diameter, Connection “3“ and “4“	D3	D3_AUSSEN
Wall thickness, Connection “!“ and “2“	S	WANDDICKE
Wall thickness, Connection “3“ and “4“	S3	WANDDICKE3

If required, the attributes LAENGE, LAENGE1 and LAENGE3 need to be assigned to the length variables (see Variables names above).

For variant synchronization you also need to enter the values for the attributes which are to apply to all sub-types of the variant.

Values must be entered for at least the following attributes:

Attribute

Description

BENENNUNG

Designation of part

COMPONENT_TYPE

Part type (always = Semi-finished material + Plant Engineering) for HELiOS database only

NORMBEZEICHNUNG

Standard designation of the part (identical for all sub-types!)

An entry is mandatory, even if the part corresponds to no standard.

ANSCHLUSSART (CONNECTION_TYPE)

Connection type for Connection “!“, “2“, “3“ and “4“

Possible values of the attribute ANSCHLUSSART (CONNECTION_TYPE):.

1000x	Butt-welded	Provide auxiliary part when fitting part If appropriately preset in the ANSCHLUSSART (CONNECTION_TYPE) attribute for a connection, the part will provide and connect an auxiliary part of the standard specified in the attribute for the connection when being fitted. For example, if the part has a flange connection and the corresponding counter-flange is required, the content of the ANSCHLUSSART (CONNECTION_TYPE) attribute could look as follows: 20002 1 5100010 EN 1092-1/11/A/PN 40 EN 1092-1/11/A/PN 40 is the standard designation with which the flange is to be entered into the database.
2000x	Flange connection
2100x	Flange with groove connection
2200x	Flange with notch connection
2040x	Flange connection of a part that is not a flange itself. The part has a loose flange that is modelled as a sub-part and has no own article master attached to this connection.
3100x	Screwed, nipple
3200x	Screwed, socket
4100x	Plugged, nipple
4200x	Plugged, socket
5100x	Socket-welded, nipple
5200x	Socket-welded, socket

The last character (x) provides information about the meaning of the supplement:

0 =No supplement

2 = The supplement consists of connection number, part type, ID, and standard of the part to be connected

The prefixed connection number indicates the connection with which the auxiliary part is to be attached to the current connection.

Please also read the information given in the paragraphs Connection type ID with priority information and Connection type ID - List of part standards.

Handling of nominal diameters in inches in the HELiOS database:

During part data synchronization, nominal diameters in inches will be taken over to the attributes N_INCH, N2_INCH and N3_. The usual character strings for indication of the diameter in inches (e.g. 1 1/2‘‘ instead of 1.5) will be auto-generated in the database for the attributes NPS_INCH, NPS2_INCH und NPS3_INCH.
