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])
Maximum Pressure Drops
See tables 4, 5, 6, and 7
Input Signal to Actuator
See tables 4, 5, 6, and 7
Actuator Maximum Casing Pressure
3.4 bar (50 psig)
Shutoff Classification per ANSI/FCI 70‐2
and IEC 60534‐4
Class IV
1. The pressure or temperature limits in the referenced tables and any applicable ASME code limitations should not be exceeded.

Specifications

Table 1 lists specifications for the D4 control valve. Some of the specifications for a given control valve as it originally
comes from the factory are stamped on a nameplate located on the actuator spring barrel.
