Re: pic: Servo Controlled Valve

NO. No modification of the valve occurred. It is simply a "knob turner". The valve's knob was NOT modified, and it is retained within the box only via the SMC connectors (no leaks!).

Gee... I see that CDF put the pic up before I had a chance to add my comments. (Wow! 99 views already while I typed!) Please look at the text now supplied, for construction and usage notes.

I hoping that this design may be found useful for:
-- a rookie team with limited budget for real control valves,
-- someone wishing a non-piloted valve for vacuum or low pressure cylinder apps (below what kit valves can control),
-- a team that wishes to make a Starting-to-Operating configuration transformer setup, without wasting an expensive kit valve for the purpose,
-- any application where you need to isolate a subsystem (IOW prevent something from working) from start of round until the desired critical moment, or
-- stopping a cylinder in a mid-position, by plugging the vent port.

BTW, if you DO replicate this in some version, PLEASE drop me a note to tell me your mods, and how you used it! Good luck with your build!
