Here are two views of the 4 inch butterfly valve and modified (a little) car window operator that modulates the valve to keep the voltage steady as power demand varies.Frustration overcame when I tried to upload PDF files to my blog, so here is a link to the PDF diagram for the valve controller. The butterfly valve is driven by a car electric window operator becaus
e of its high torque and harsh environment operating capability. The controller was built to operate 2 valves and has battery backup for manual control, when all else fails.http://www.scribd.com/doc/3198857/Valve-Voltage-Frequency-Control-Circuit

Complex control systems using valves requires an automatic control based input of an actuator. The actuator strokes the valve allowing the valve to be positioned accurately and allowing control over a variety of requirements.
There is obviously a lot to know about this. I think you made some good points in Features also. Keep working ,great job!
Ich habe einige wunderbare Weisheit.
