We have motorized ball valves available with 4 distinct wiring types. The simplest model is the 2 wire reverse polarity. These can be used in conjunction with a DPDT switch, as simply switching the polarity reverses the action of the actuator. We also offer a two wire auto return valve. This is great for instances when the valve should return to the closed position in case of a power shortage. The three wire model allows for two points of control. Finally, the 5 wire model allows for indicator lights, in systems where it is important to have visual cues as to the status of the valve.
