Maximum Inlet Pressures and Temperatures
If the valve nameplate shows an ASME
pressure-temperature class, maximum inlet
pressure and temperature is consistent with the
applicable class per ASME B16.34. If the
nameplate does not show an ASME class, it will
show a maximum cold working pressure at 38_C
(100_F) (for example, 248 bar [3600 psi])
