The Flowrite 599 Series two-way valves are designed to work with either a
pneumatic or electronic actuator with a 3/4-inch (20 mm) stroke. They are available
in ANSI Class 250 for normally open or normally closed action.
• ANSI Leakage Class IV (0.01% of Cv)
• Cartridge type packing
• Choice of brass or stainless steel trim
• Direct-coupled universal bonnet
• UF×UF connections available
• Choice to two flow characteristics
Flowrite valves are generally recommended for water, steam, and 50% water-glycol
solutions.
See Tables 1 and 2.
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 numbers in Tables 1 and 2.

Operation
Figure 5 shows the normally open valve in
the open or full flow position and the
normally closed valve in the closed or zero
flow position. The actuator spring provides
the necessary force to hold the stem in the
raised or normal position.
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.

Sizing
Mounting and
Installation
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, such as steam, 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 Tables 3 through 6 for valve capacities.
• 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 12 for valve
body dimensions. See Figure 6 and Table 11 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.
