INST Symbol Keys

Notes:

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:
   That the horizontal offset may be zero; that means, 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:
   That the horizontal offset may be zero; that means, 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.
