Three-Way Valves
2-1/2 to 6-inch Flanged Iron Body
Description The Flowrite VF 599 series three-way valves are designed to work with either a
pneumatic or electronic actuator. They are available in both ANSI Class 125 and 250.
Features •Valve flange face-to-face dimensions meet ISA 75.03 standards
•Direct coupled universal bonnet
•Choice of bronze or stainless steel trim
•ANSI Leakage Class IV (0.01% of Cv)
•Cartridge type packing
•Optional service flange available
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.

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 155-304P25 (TB 249)
for selection procedure and ordering codes.
Valve assemblies can be ordered using the numbers in Table 1.
The service flange is ordered separately.

Operation
This Flowrite three-way valve is designed as a mixing
valve.
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. Non-spring
return actuators will hold the last commanded
position. See the Technical Instructions of the
various actuators for additional information.
If this valve is used in diverting applications, the
following conditions apply:
Diverting service with modulating control can only
use the electro-hydraulic actuator, SKB/C. 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 may 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 which must be determined are:
•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.
•The maximum capacity the valve must deliver.
•The maximum line pressure differential the valve actuator must close against.
•See AB-1 Control Valve Selection and Sizing (Document Number 155-285) for
further recommendations.
See Tables 6 and 7 for valve capacities.
Mounting and
Installation
•Install the valve so that the flow follows the direction of the arrow indicated on the
valve body identification tag.
•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 below horizontal or upside down.
•If installing a service flange, see Table 13 for proper placement.
•For flange dimensions and bolt hole information, see 155-303P25 (TB 248).Allow
sufficient space for servicing the valve and actuator. See Table 12 for valve body
dimensions. See Figure 5 and Table 11 for dimensions of the service envelope
recommended around the actuator.
•A lower seat tool is required for removing a three-way valve. See Table 10 for part
numbers.
NOTE: Instructions for field mounting an actuator, spring adjustments, wiring diagrams,
and start-up are covered in the Technical Instructions and Installation
Instructions for each actuator.
