High Pressure Close-Off 2-Way
Valves, 2-1/2 to 6-Inch, Flanged Iron
Body, ANSI Classes 125 & 250
Description
The Flowrite 599 Series High Pressure Close-off, two-way flanged valve bodies, are
designed to work with either pneumatic or electronic actuators with 3/4-inch (20 mm) or
1-1/2-inch (40 mm) stroke. They are available in both ANSI Class 125 and 250 for
normally open or normally closed action.
Features
• Valve flange face-to-face dimensions meet ISA 75.03 standards.
• Universal bonnet for direct-coupled actuators
• Equal percentage flow characteristic
• Stainless steel trim
• ANSI Leakage Class IV
• EPDM O-ring packing
Application
These Flowrite valves are recommended for chilled or hot water; or 50% water-glycol
solutions.
• ANSI 125 and ANSI 250 cast iron body rating.
• Maximum recommended differential pressure for modulating service; 50 psi (345 kPa).
Product Numbers
See Tables 1 and 2.
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. Valves can be ordered
using the numbers in Tables 1 and 2.

Operation
Figure 3 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.
Normally Open Normally Closed
Figure 3. Operation.
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 may 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 water and 50% water-glycol solutions, are the controlled mediums.
• 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 that the valve actuator must close against.
See Tables 5 through 6, and Figure 2 for valve capacities and sizing selection.

Installation
Install the valve so that the flow follows the direction of the arrow indicated on the valve
body identification tag.
CAUTION:
Install the valve assembly with the actuator above the valve body. The
valve and actuator can be installed in any position between:
• Horizontal to the valve; and
• Vertical above the valve.
It is not recommended to install the valve assembly below horizontal or
upside down.
Figure 4. Recommended Installation Orientations.
• For flange dimensions and bolt hole information, see 155-303P25 (TB 248).
• Allow sufficient space for servicing the valve and actuator. See Table 11 for valve
body dimensions. See Figure 7 and Table 10 for dimensions of the service
envelope recommended around the actuator.
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.
