Valve and Actuator Selection
Procedure
Globe Valve Assembly Selection Procedure
When selecting a globe valve assembly, first determine the appli-
cable 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 Connec-
tion
Refer to the Assembly Ordering to 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. Refer
to the separately available Wiring, Dimensions and Reference
Document F-28125 from the Exchange download center.
b. Select the nearest available Cv value and corresponding valve
body port code from Assembly Ordering.
3. Actuator
Select the appropriate actuator and code, according to Assembly
Ordering based on the control signal type, required valve normal posi-
tion, and voltage requirements. For detailed actuator information, refer
to Pg. 61, 4. VB-7000 Series Globe Valves Actuators & Linkages for
applicable actuator specifications.
4. Close-off Pressure
Confirm, with respect to Actuator Close-Off Capacity, that the selected
actuator and valve body combination provides sufficient close-off
pressure. If no close-off pressure is shown, the valve body/actuator
combination is not valid.
5. Available Space
If available space is a consideration, check the appropriate figure in
the separately available Wiring, Dimensions and Reference document
F-28125 from the Exchange Download Center.
