Hi guys, looking to pick the vast wealth of experience here. I have a Slitter Machine (John Dusenbury Co. Inc.) which has a SMC E/P Regulator valve on it. The part number is Old (NIT-201-T302) and I am still reseaching how these work. I have +15Vdc and 0V but no voltage on the Sig wire. Am I correct in saying that a varying voltage on the signal wire will open the valve propotionally? In other words, no voltage=no air, higher voltage=higher air pressure.

Thanks for any help in advance

And to answer your question "Yes" You usually have a base voltage, a common or - voltage, and a signal or reference voltage to proportionately control a device in a linear scale. Usually from and analog card or device, or a potentiometer or other scaling device.

Thanks for the reply splicer480, and conferming my thoughts on how it worked.
We ordered a new one and was able to get a copy of the manual too.
