Maximum Inlet Pressures and Temperatures
(1)
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, 293
bar [4250 psi])
