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.
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.
An improperly-tuned loop will cause excessive repositioning that will shorten the life of the
actuator.
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.
