Globe Valve Assembly Selection Procedure
When selecting a globe valve assembly, you must determine the applicable codes
for the control signal type, valve body configuration, end connection, port size and
actuator. Select a globe valve assembly part number as follows:
1. Control Signal Type, Valve Body Configuration and End Connection
Refer to Assembly Ordering and select the appropriate codes for the part-number
fields.
2. Valve Size (Flow Coefficient)
If the required flow coefficient (Cv) has not been determined, do so as follows:
a. Refer to Sizing and Selection to calculate the required Cv.
b. Select the nearest available Cv value and corresponding valve body port code
from the “Part Numbering System.”
3. Actuator
Select the appropriate actuator and code, according to Assembly Ordering based
on the control signal type, required valve normal position, and voltage requirements.
For detailed actuator information, refer to the applicable actuator specifications on
subsequent pages.
4. Close-off Pressure
Confirm that the selected actuator and valve body combination provides sufficient
close-off pressure. If no close-off pressure is shown, the valve body/actuator combi-
nation is not valid.
5. Available Space
If available space is a consideration, check the appropriate dimensional figure and
its accom panying table for any potential fit issues.
