See Figure 1.
Select a valve given:
Required flow = 20 gpm.
Desired pressure drop = 5 psi.
Choose a 1-inch (25 mm) valve, Cv 10.

Figure 2. Close-off Pressures.
Operation As the valve stem moves downward, the flow through the
NO port decreases and the flow through the NC port
increases. As the valve stem moves upward, the flow
through the NO port increases and the flow through the
NC port decreases.
In the event of power failure, a fail-safe actuator returns
the valve to its normal position. Fail-in-place actuators will
hold the last commanded position. See the Technical
Instructions of the various actuators for additional
information.
Figure 3.
Sizing The sizing of a valve is important for correct system operation. An undersized valve will
not have sufficient capacity at maximum load. An oversized valve can initiate cycling,
and the seat and throttling plug can be damaged because of the restricted opening.
Correct sizing of the control valve for actual expected conditions is considered essential
for good control.
The following variables must be determined:
•The medium to be controlled: water, etc.
•The maximum inlet temperature and pressure of the medium at the valve.
•The pressure differential that will exist across the valve under maximum load
demand.

Page 6Siemens Industry, Inc.
Sizing, Continued •The maximum capacity the valve must deliver.
•The maximum line pressure differential the valve actuator must close against.
See Application Bulletin (AB)-1 Control Valve Selection and Sizing (155-285) for further
recommendations.
See Tables 3 and 4 for valve capacities.
Mounting and
Installation Install the valve so that the flow follows the direction of the arrow indicated on the valve
body.
For best performance, install the valve assembly with the actuator above the valve body.
The valve and actuator can be installed in any position between vertical and horizontal.
It is not recommended to install the valve assembly so that the actuator is below
horizontal or up side down.
Allow sufficient space for servicing the valve and actuator. See Table 6 for valve body
dimensions. See Figure 5 and Table 7 for dimensions of the service envelope
recommended around the actuator.
NOTE: Instructions for field mounting an actuator, wiring diagrams, and start-up
are covered in the Technical Instructions and Installation Instructions for
each actuator.
Service Replace the valve if inoperable.
Dimensions See Table 6 for valve body dimensions. The letters in Figure 5 refer to the valve
centerline to top of actuator, the actuator width, and service envelope dimensions in
Table 7.
