This Flowrite Rack and Pinion Valve Actuator is used with 1/2 to 2-inch Flowrite 2-way and 3-way valves with a 3/4-inch stroke. This electronic rack and pinion actuator has an operating voltage of 24 Vac, 0 to 10 Vdc proportional control, and bi-directional fail-safe spring return. Other features of this rack and pinion include all metal housing, and brushless DC motor technology with stall protection.; Datasheet
The Siemens 599-03609 Linkage WITH GCA161.1U
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
