dixonvalve.comPressure - Temperature Ratings
•
Ratings apply to all products covered by ANSI 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).Temperatures are those on the inside of the pressure retaining structure.
•
The use of these ratings requires gaskets conforming to the requirements of ANSI 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.
