Pressure - Temperature Ratings
Note: Ratings apply to all products covered by USA B16.5
valves conforming to the requirements of this standard must,
in other respects, merit these ratings.
All ratings are maximum allowable non-shock pressures
(PSIG) at the tabulated temperatures (degree Fahrenheit)
and may be interpolated between temperatures shown. The
primary service pressure ratings are shown in bold face type.
Temperatures are those on the inside of the pressure retaining
structure.
The use of these ratings requires gaskets conforming to
the requirements of USA B16.5. The user is responsible for
selecting gaskets of dimensions and materials to withstand the
required bolt loading without injurious crushing, and suitable
for the service conditions in all other respects.

Note: For hose I.D.'s from 1-1/4" to 12" the force in pounds is greater than the PSI.
• Force is the dynamic power which is exported longitudinally through a hose, towards the ends. To arrive at the number of
pounds of force exerted, you merely multiply the area of the I.D. times the working pressure being used.
• Area of a circle: r2 (PI [3.1416] times radius squared)
• Force = Area x Pressure
