Globe Valve Assembly Selection Procedure
When selecting a globe valve assembly, first determine the applicable codes for the
control signal type, valve body configuration, end connection, port size and actuator
according to Assembly Ordering on the next pages. 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. Refer to the sepa-
rately 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 on the
next pages based on the control signal type, required valve normal position, and volt-
age 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 pres-
sure 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.
