2.3. Non-Standard Valves

Certain type valves do not conform entirely to ASME pressure and

temperature ratings or the standards mentioned

in

this specification.

In

such

cases, valves that differ somewhat

in

pressure rating or temperature limits

from those of the manufacturer and model number listed in the material

requisitions may be offered. Any exceptions to the description in the material

requisition form, however, must

be

clearly noted
