Three-Way Valves
1/2 to 2-inch Bronze Body
Siemens Industry, Inc.
Description The Flowrite VF 599 Series ANSI Class 250 three-way valves are designed to work with
either a pneumatic or electronic actuator with a 3/4-inch (20 mm) stroke.
Features •ANSI Leakage Class IV (0.01% of Cv)
•Cartridge type packing
•Choice of brass or stainless steel trim
•Direct-coupled universal bonnet
Application A typical application for the Flowrite three-way valve is the mixing of two different
temperatures of water supplies.
The valve can also be used for throttling or bypass coil control applications. A pump is
recommended on the coil circuit to improve the heat transfer characteristics of the coil
and for freeze protection.
Product Numbers See Table 1.
Ordering a Valve
Plus Actuator
Assembly
To order a complete valve plus actuator assembly from the factory, combine the
actuator prefix code with the suffix of the valve assembly product number. See Flowrite
Technical Bulletins 155-772 and 155-776 for complete selection procedure and ordering
codes.
Valve assemblies can be ordered using the valve part numbers in Table 1 and the
actuator prefix codes in Table 7.

Figure 4. 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 spring return
actuator returns the valve to its normal position with
the upper port closed and the bottom port open.
Non-spring return actuators will hold the last
commanded position. See the Technical
Instructions of the various actuators for additional
information.
Figure 5.
If this valve is used in diverting applications, the following conditions apply:
Diverting service with modulating control can use mechanical actuators such as the
SAX and SKB/D. The differential pressure must not exceed 90% of the maximum
differential pressure specified for the three-way valve in mixing service.
Diverting service with a pneumatic actuator can only be used with two-position control.
To change over from one port to another there must be no system pressure. The pump
is turned off.

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.
Some variables that must be determined are:
•The medium to be controlled, such as 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.
•The maximum capacity the valve must deliver.
•The maximum line pressure differential the valve actuator must close against.
•See the Control Valve Selection and Sizing (AB-1) section of HVAC
Systems/Controls Reference Data (125-1853) for further recommendations.
See Table 2 and Table 3 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. Siemens Building Technologies does not recommend installing the valve
assembly so that the actuator is below horizontal or upside down.
•Allow sufficient space for servicing the valve and actuator. See Table 8 for valve
body dimensions. See Figure 6 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.
