VB-9313
Applications
Schneider Electric Forta M900Axx Series Spring Return Actuators mount directly with
AV-822 onto 2½…4" VB-9313 Series flanged globe valve bodies. Applications include
chilled or hot water and steam NEMA 1 or 2 (M900Ax) or NEMA 4 (M900AxW)
models. Field selectable input signals include reverse and direct acting, floating or
proportional 0…10 Vdc, 2…10 Vdc or 4…20 mA, and proportional sequencing input
signal ranges.

Valve and Actuator Selection Procedure
1. Determine the required flow coefficient (Cv/kvs).
Using the required flow and pressure drop for the application, determine the required
flow coefficient (consult CA28, F-13755 if necessary).
2. Determine valve body part number.
Select a flanged VB-9313 valve body having the required flow coefficient, size, body
pattern, end connection, and temperature/pressure ratings appropriate for the ap-
plication. Determine the desired loss of power position of the valve.
3. Select the Forta Actuator
Using the required close-off pressure for the application and the appropriate spring
return action and select a Forta actuator having sufficient close-off pressure on the
valve body selected in step 2. For valve/actuator combinations using VB-9313 valve
bodies, also consult the tables for maximum operating pressure differential limita-
tions.
If necessary, use the dimensional information on the VB-9000 Series
With M900A Series of the Dimensions section to confirm that the valve-actuator as-
sembly will fit in the available space.
4. Determine the Assembly Part Number
If a complete factory valve and actuator assembly is required, consult the tables in
this section for the actuator code of the Forta actuator selected in Step 3. For the
complete assembly part number:
Change the valve body part number prefix from VB to VU. Insert the actuator code in
the third field of the part number. Confirm the factory assembly is available in iPortal.
Example:
Valve body: VB-9313-0-5-14
Actuator: M900AR (actuator code 650 from tables in this section)
Complete assembly: VU-9313-650-5-14
Forta actuators are field configured for the desired control signal type and range plus
the desired action. Consult the appropriate Forta Installation Instructions for further
information.
