599 Series Rack & Pinion
Valves
Siemens Industry, Inc.
Description
The Flowrite 599 Series Rack & Pinion Valve couples the OpenAir™ Actuator to a 1/2-
to 2-inch Flowrite 599 Series two- or three-way valve via a linkage. The linkage
transforms the actuator rotary movement into the linear motion required to position the
valve.
Features
•Brushless DC motor technology with stall protection
•Bi-directional fail-safe spring return (actuator dependent)
•Direct or reverse acting selectable by field installation
•All metal housing
Application
The Flowrite valves are used to control water and glycol solutions to 50 percent in small
to large air handling units and central plant applications.
Warning/Caution
Notations
WARNING:
Personal injury or loss of life may occur if you do not perform a
procedure as specified.
CAUTION:
Equipment damage may occur if you do not perform a
procedure as specified.

Operation
599-03609 assembly
with GCA161.1U
actuator
A continuous 0 to 10 Vdc signal from a controller to Terminal Y (8, gray) of a
normally-closed, direct-acting assembly operates the actuator and the valve opens
respectively. The linkage proportionally translates the rotary actuator stroke into a linear
valve stem motion.
A 0 to 10 Vdc position output feedback signal at Terminal U (9, pink) is available to
monitor the position of the actuator.
In the event of a power failure or when the operating voltage is absent, the actuator
returns to the fail-safe (90) position and the valve closes.
In the event of a stall, the actuator is overload protected over the full range to prevent
damage.
599-03611 assembly
with GCA121.1U
actuator
When power is applied to a normally-closed, direct-acting assembly, the actuator moves
to the full-open (-5) position and the valve opens. The linkage translates the rotary
actuator stroke into a linear valve stem motion.
In the event of a power failure or when operating voltage is absent, the actuator returns to
the fail-safe (90) position and the valve closes.
In the event of a stall, the actuator is overload protected over the full range to prevent
damage.
Life expectancy
An improperly-tuned loop will cause excessive repositioning that will shorten the life of the
actuator.
Installation and
Mounting
Flowrite Rack & Pinion Valves are suitable for water applications where, the actuator
mounts on the linkage vertically. Units are shipped from the factory in the vertical position.
Flowrite Rack & Pinion Valves can be installed on normally-closed, normally-open, and
three-way Flowrite valves for direct or reverse-acting control applications. The actuator
orientation and the position of the actuator shaft adapter on the linkage determine whether
the linkage shaft rotates clockwise or counterclockwise for the proper control action.
Flowrite 599 Series Rack & Pinion Valves Installation Instructions (129-292), shipped with
the assembly, provides details to configure the assembly for the desired control
application.
For applications using an alternate OpenAir Electronic Actuator on the linkage, the
actuator preload must be reset. Flowrite 599 Series Rack & Pinion Valves Installation
Instructions (129-292), shipped with the assembly, provides preload details.
Install the Flowrite Rack & Pinion Valve so that the flow of the medium follows the
direction of the arrow cast on the valve body. For best performance, install the valve with
the actuator above the valve body. Figure 1 shows acceptable NEMA 2 mounting
positions. Do not mount the assembly so that the actuator is below horizontal or upside-
down.
Allow sufficient space for servicing the assembly. See Dimensions and the recommended
service envelope in Figure 2.

Wiring
All wiring must conform to NEC, and to local codes and regulations.
Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers.
Determine the supply transformer rating by summing the total VA of all actuators used.
The maximum rating for a Class 2 step-down transformer is 100 VA.
Table 2 shows the recommended maximum actuators per Class 2 circuit and includes a
safety factor of 80% of the transformer VA. Operating additional actuators requires
additional transformers or separate 100 VA power trunks.
