CW2M is not listed in ASME
B16.34. The designations 150, 300,
and 600 indicate relative
pressure-retaining capabilities and
are not ASME
pressure-temperature rating
classes.
Shutoff Pressure Drop Limits for Trim Parts
WARNING
Pressure drops in the following table consider
only the trim parts (ball, shafts, bearings, and
seals).
The pressure drops shown might be higher than
the EN or ASME pressuretemperature rating of
the valve body or mating flanges. Do not exceed
the EN or ASME pressure-temperature rating of
the valve or mating flanges, as exceeding the
pressure-temperature rating may cause personal
injury or equipment damage.
In the following tables, the lower temperature limit is
10C for EN valves, 29C for ASME steel valves,
and 46C for ASME stainless steel valves.
Also refer to the actuator sizing pages to select an
actuator size.
Table 13. Pressure Drop in Bar (For HD Metal Seal, Pressure Drops are for Forward Flow Only. For Reverse HD Seal Flow, Limit
Pressure Drop to 6.9 Bar)
