VG1841 and VG1845 Series Three-Way Ball Valves have a different port configuration from VG1644 Series Three-
Way valves. See Figure 2, Figure 3, and Figure 4 for details.
Contact your local Johnson Controls® representative for compatibility concerns before using VG1000 Series Ball
Valves to control the flow of fluids other than those outlined in the Technical Specifications
table in this document.
IMPORTANT: Protect the actuator from dripping water, condensation, and other moisture. Water or moisture
could result in an electrical short, which may damage or affect the operation of the actuator.
IMPORTANT: Do not cover the actuator with thermal insulating material. High ambient temperatures may
damage the actuator, and a hot water pipe, steam pipe, or other heat source may overheat it.
