A. Process pressure, psig (barg)
B. Process temperature, °F (°C)
The final rating depends on the selected process connection.
Threaded connection
See Figure A-1 .
Tri Clamp connection
435 psig (30 barg)
Flanged connection
The maximum operating pressure is the lower of the process pressure ( Figure A-1 ) and
flange pressure rating (see Table A-4 ).

(1) At 100 °F (38 °C), the pressure rating decreases with an increasing process temperature.
(2) At 122 °F (50 °C), the pressure rating decreases with an increasing process temperature.
(3) At 248 °F (120 °C), the rating decreases with an increasing process temperature.
