Technical Instructions Document No. 155-541P25 October 15, 2018 Flowrite™ 599 Series Rack & Pinion Valves Description Features The Flowrite 599 Series Rack & Pinion Valve couples the OpenAir™ Actuator to a 1/2to 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.

Technical Instructions Document No. 155-541P25 October 15, 2018 Flowrite 599 Series Rack & Pinion Valves 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.
FlowriteTM 599 Series Rack & Pinion Valves Technical Instructions Document No. 155-541P25 October 15, 2018 Figure 1. Acceptable NEMA 2 Mounting Positions. 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.
