INST Symbol Keys

1

Replace the ** characters in the symbol key with one of the following end condition identifiers:

BW for butt weld

CP for compression

SW for socket weld

FL for flanged

SC for screwed

PL for plain

2

To use this symbol, the p-points must be arranged as shown in the following diagram:

3

To use this symbol, the p-points must be arranged as shown in the following diagram:

Note: The horizontal offset may be zero; that is, P0, P1, P2, and P3 may be coplanar.

4

To use this symbol, the p-points must be arranged as shown in the following diagram:

Note: The horizontal offset may be zero; that is, P0 and P1 (and similarly P2 and P3) may be coincident.

5

If an orientation p-point (P3) is present in the point set and is oriented away from the XYZ axes, then the orientation of this p-point will be shown on the isometric.

6

Instrument dials can have a P3 with an unset bore for orienting the dial. This p-point will normally be positioned perpendicular to the dial face, on the dial axis. A message will be output near the component showing the orientation of P3.

7

P-Point 11 is the Spindle attachment point and its PURP attribute should be set to 'SPIN'. These Multiport Valves may have up to two flushing/draining connections:

• These must be P-Point 9 and P-Point 10.

• The isometric will only show a symbolic line and a note CONT TO "name" for each connection.

• There will be no materials or isometric representation of the branch connection to these points.
