How can I tell if the butterfly valve is using a Siemens actuator?
In the part number configuration of the butterfly valve, places 8 & 9 identify the actuator. If place 8 is a G, then the actuator is a Siemens OpenAir actuator. If there is an S2 in these spots, a Siemens (Powers) 6″ pneumatic actuator will be used on 8″ and smaller 2-way valves and 6″ and smaller 3-way valves.
