Cold Working Pressure (CWP) Rating ◦ Rating of valve at ambient conditions,

usually from –20 to 100°F

Pressure Rating ◦ The maximum operating pressure established by the

Manufacturer

Temperature Ratings ◦ The maximum and minimum temperatures at which

the valve can be used.

ASME B16.5

Stamped vessel pressure ratings VS flange ratings ◦ Stamped vessels are design to any working pressure

◦ Flange pressure rating must match or exceed the maximum working pressure of the unit

Stamped vessel pressure ratings ◦ Maximum working pressures are from –20 to 100°F and

subject to derating at elevated temperatures per ASME Code

Test pressures ◦ Covered by ASME Code and are only tested to 1.3 x Design

Working Pressure

◦ Buyer must specify a higher test pressure if desired
